              ''' IPython customization API
              Your one-stop module for configuring & extending ipython
              The API will probably break when ipython 1.0 is released, but so
              will the other configuration method (rc files).
              All names prefixed by underscores are for internal use, not part
              of the public api.
              Below is an example that you can just put to a module and import from ipython.
              A good practice is to install the config script below as e.g.
              ~/.ipython/my_private_conf.py
              And do
              import_mod my_private_conf
              in ~/.ipython/ipythonrc
              That way the module is imported at startup and you can have all your
              personal configuration (as opposed to boilerplate ipythonrc-PROFILENAME
              stuff) in there.

                      This utility routine is meant to ease interactive debugging work,
                      where you want to easily propagate some internal variable in your code
                      up to the interactive namespace for further exploration.
                      When you run code via %run, globals in your script become visible at
                      the interactive prompt, but this doesn't happen for locals inside your
                      own functions and methods.  Yet when debugging, it is common to want
                      to explore some internal variables further at the interactive propmt.
                      Examples:
                      To use this, you first must obtain a handle on the ipython object as
                      indicated above, via:
                      import IPython.ipapi
                      ip = IPython.ipapi.get()
                      Once this is done, inside a routine foo() where you want to expose
                      variables x and y, you do the following:
                      def foo():
                          ...
                          x = your_computation()
                          y = something_else()
                          # This pushes x and y to the interactive prompt immediately, even
                          # if this routine crashes on the next line after:
                          ip.to_user_ns('x y')
                          ...
                          # return
                      If you need to rename variables, just use ip.user_ns with dict
                      and update:
                      # exposes variables 'foo' as 'x' and 'bar' as 'y' in IPython
                      # user namespace

0 +3 0

 -04-20  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipy_render.py: added extension for easy
              	interactive text template rendering (todo - add a better
              	renderer than string.Template)
              	* Extensions/ipy_completers.py: introduced Olivier Lauzanne's
              	safer & faster 'import' completer.
+             	* Introduced new ipapi methods, _ip.defmacro(name, value)
+             	and _ip.defalias(name, command).
 -04-19  Ville Vainio  <vivainio@gmail.com>
              	* upgrade_dir.py: skip junk files like *.pyc
              	* Release.py: version number to 0.8.1
 -04-18  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py (safe_execfile): make "ipython foo.py" work with 2.5.1c1
              	and later on win32.
 -04-16  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py (showtraceback): Do not crash when running w/o readline.
 -04-12  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: (ils) Directoy listings are now
              	sorted (case sensitive with files and dirs mixed).
 -04-10  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Release.py (version): Open trunk for 0.8.1 development.
 -04-10  *** Released version 0.8.0
 -04-07  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* Tag 0.8.0 for release.
              	* IPython/iplib.py (reloadhist): add API function to cleanly
              	reload the readline history, which was growing inappropriately on
              	every %run call.
              	* win32_manual_post_install.py (run): apply last part of Nicolas
              	Pernetty's patch (I'd accidentally applied it in a different
              	directory and this particular file didn't get patched).
 -04-05  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (MAIN_THREAD_ID): get rid of my stupid hack to
              	find the main thread id and use the proper API call.  Thanks to
              	Stefan for the fix.
              	* test/test_prefilter.py (esc_handler_tests): udpate one of Dan's
              	unit tests to reflect fixed ticket #52, and add more tests sent by
              	him.
              	* IPython/iplib.py (raw_input): restore the readline completer
              	state on every input, in case third-party code messed it up.
              	(_prefilter): revert recent addition of early-escape checks which
              	prevent many valid alias calls from working.
              	* IPython/Shell.py (MTInteractiveShell.runcode): add a tracking
              	flag for sigint handler so we don't run a full signal() call on
              	each runcode access.
              	* IPython/Magic.py (magic_whos): small improvement to diagnostic
              	message.
 -04-04  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (sigint_handler): I *THINK* I finally got
              	asynchronous exceptions working, i.e., Ctrl-C can actually
              	interrupt long-running code in the multithreaded shells.
              	This is using Tomer Filiba's great ctypes-based trick:
              	http://sebulba.wikispaces.com/recipe+thread2.  I'd already tried
              	this in the past, but hadn't been able to make it work before.  So
              	far it looks like it's actually running, but this needs more
              	testing.  If it really works, I'll be *very* happy, and we'll owe
              	a huge thank you to Tomer.  My current implementation is ugly,
              	hackish and uses nasty globals, but I don't want to try and clean
              	anything up until we know if it actually works.
              	NOTE: this feature needs ctypes to work.  ctypes is included in
              	Python2.5, but 2.4 users will need to manually install it.  This
              	feature makes multi-threaded shells so much more usable that it's
              	a minor price to pay (ctypes is very easy to install, already a
              	requirement for win32 and available in major linux distros).
 -04-04  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipy_completers.py, ipy_stock_completers.py:
              	Moved implementations of 'bundled' completers to ipy_completers.py,
              	they are only enabled in ipy_stock_completers.py.
 -04-04  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/PyColorize.py (Parser.format2): Fix identation of
              	colorzied output and return early if color scheme is NoColor, to
              	avoid unnecessary and expensive tokenization.  Closes #131.
 -04-03  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Debugger.py: disable the use of pydb version 1.17.  It
              	has a critical bug (a missing import that makes post-mortem not
              	work at all).  Unfortunately as of this time, this is the version
              	shipped with Ubuntu Edgy, so quite a few people have this one.  I
              	hope Edgy will update to a more recent package.
 -04-02  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (_prefilter): close #52, second part of a patch
              	set by Stefan (only the first part had been applied before).
              	* IPython/Extensions/ipy_stock_completers.py (module_completer):
              	remove usage of the dangerous pkgutil.walk_packages().  See
              	details in comments left in the code.
              	* IPython/Magic.py (magic_whos): add support for numpy arrays
              	similar to what we had for Numeric.
              	* IPython/completer.py (IPCompleter.complete): extend the
              	complete() call API to support completions by other mechanisms
              	than readline.  Closes #109.
              	* IPython/iplib.py (safe_execfile): add a safeguard under Win32 to
              	protect against a bug in Python's execfile().  Closes #123.
 -04-01  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (split_user_input): ensure that when splitting
              	user input, the part that can be treated as a python name is pure
              	ascii (Python identifiers MUST be pure ascii).  Part of the
              	ongoing Unicode support work.
              	* IPython/Prompts.py (prompt_specials_color): Add \N for the
              	actual prompt number, without any coloring.  This allows users to
              	produce numbered prompts with their own colors.  Added after a
              	report/request by Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
 -03-31  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/igrid.py: Map the return key
              	to enter() and shift-return to enterattr().
 -03-30  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_psearch): add unicode support by
              	encoding to ascii the input, since this routine also only deals
              	with valid Python names.  Fixes a bug reported by Stefan.
 -03-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (_inspect): convert unicode input into ascii
              	before trying to evaluate it as a Python identifier.  This fixes a
              	problem that the new unicode support had introduced when analyzing
              	long definition lines for functions.
 -03-24  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/igrid.py: Fix picking. Using
              	igrid with wxPython 2.6 and -wthread should work now.
              	igrid.display() simply tries to create a frame without
              	an application. Only if this fails an application is created.
 -03-23  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/path.py: Updated to version 2.2.
 -03-23  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: recursive alias expansion now works better, so that
              	cases like 'top' -> 'd:/cygwin/top' -> 'ls :/cygwin/top'
              	doesn't trip up the process, if 'd' has been aliased to 'ls'.
              	* Extensions/ipy_gnuglobal.py added, provides %global magic
              	for users of http://www.gnu.org/software/global
              	* iplib.py: '!command /?' now doesn't invoke IPython's help system.
              	Closes #52. Patch by Stefan van der Walt.
 -03-23  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/FakeModule.py (FakeModule.__init__): Small fix to
              	respect the __file__ attribute when using %run.  Thanks to a bug
              	report by Sebastian Rooks <sebastian.rooks-AT-free.fr>.
 -03-22  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (raw_input): Fix mishandling of unicode at
              	input.  Patch sent by Stefan.
 -03-20  J�rgen Stenarson  <jorgen.stenarson@bostream.nu>
              	* IPython/Extensions/ipy_stock_completer.py
              	shlex_split, fix bug in shlex_split. len function
              	call was missing an if statement. Caused shlex_split to
              	sometimes return "" as last element.
 -03-18  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/completer.py
              	(IPCompleter.file_matches.single_dir_expand): fix a problem
              	reported by Stefan, where directories containign a single subdir
              	would be completed too early.
              	* IPython/Shell.py (_load_pylab): Make the execution of 'from
              	pylab import *' when -pylab is given be optional.  A new flag,
              	pylab_import_all controls this behavior, the default is True for
              	backwards compatibility.
              	* IPython/ultraTB.py (_formatTracebackLines): Added (slightly
              	modified) R. Bernstein's patch for fully syntax highlighted
              	tracebacks.  The functionality is also available under ultraTB for
              	non-ipython users (someone using ultraTB but outside an ipython
              	session).  They can select the color scheme by setting the
              	module-level global DEFAULT_SCHEME.  The highlight functionality
              	also works when debugging.
              	* IPython/genutils.py (IOStream.close): small patch by
              	R. Bernstein for improved pydb support.
              	* IPython/Debugger.py (Pdb.format_stack_entry): Added patch by
              	DaveS <davls@telus.net> to improve support of debugging under
              	NTEmacs, including improved pydb behavior.
              	* IPython/Magic.py (magic_prun): Fix saving of profile info for
              	Python 2.5, where the stats object API changed a little.  Thanks
              	to a bug report by Paul Smith <paul.smith-AT-catugmt.com>.
              	* IPython/ColorANSI.py (InputTermColors.Normal): applied Nicolas
              	Pernetty's patch to improve support for (X)Emacs under Win32.
 -03-17  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (hijack_wx): ipmort WX with current semantics
              	to quiet a deprecation warning that fires with Wx 2.8.  Thanks to
              	a report by Nik Tautenhahn.
 -03-16  Walter Doerwald  <walter@livinglogic.de>
              	* setup.py: Add the igrid help files to the list of data files
              	to be installed alongside igrid.
              	* IPython/Extensions/igrid.py: (Patch by Nik Tautenhahn)
              	Show the input object of the igrid browser as the window tile.
              	Show the object the cursor is on in the statusbar.
 -03-15  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipy_stock_completers.py: Fixed exception
                      on mismatching quotes in %run completer. Patch by
                      J�rgen Stenarson. Closes #127.
 -03-14  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ext_rehashdir.py: Do not do auto_alias
                      in %rehashdir, it clobbers %store'd aliases.
                      * UserConfig/ipy_profile_sh.py: envpersist.py extension
                      (beefed up %env) imported for sh profile.
 -03-10  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: Prefer ibrowse over igrid
              	as the default browser.
              	* IPython/Extensions/igrid.py: Make a few igrid attributes private.
              	As igrid displays all attributes it ever encounters, fetch() (which has
              	been renamed to _fetch()) doesn't have to recalculate the display attributes
              	every time a new item is fetched. This should speed up scrolling.
 -03-10  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): fix for Alex
              	Schmolck's recently reported tab-completion bug (my previous one
              	had a problem).  Patch by Dan Milstein <danmil-AT-comcast.net>.
 -03-09  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/igrid.py: Patch by Nik Tautenhahn:
              	Close help window if exiting igrid.
 -03-02  J�rgen Stenarson  <jorgen.stenarson@bostream.nu>
              	* IPython/Extensions/ipy_defaults.py: Check if readline is available
              	before calling functions from readline.
 -03-02  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/igrid.py: Add Nik Tautenhahns igrid extension.
              	igrid is a wxPython-based display object for ipipe. If your system has
              	wx installed igrid will be the default display. Without wx ipipe falls
              	back to ibrowse (which needs curses). If no curses is installed ipipe
              	falls back to idump.
 -03-01  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (split_user_inputBROKEN): temporarily disable
              	my changes from yesterday, they introduced bugs.  Will reactivate
              	once I get a correct solution, which will be much easier thanks to
              	Dan Milstein's new prefilter test suite.
 -02-28  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (split_user_input): fix input splitting so we
              	don't attempt attribute accesses on things that can't possibly be
              	valid Python attributes.  After a bug report by Alex Schmolck.
              	(InteractiveShell.__init__): brown-paper bag fix; regexp broke
              	%magic with explicit % prefix.
 -02-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): update threads calls to
              	avoid a DeprecationWarning from GTK.
 -02-22  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/genutils.py (clock): I modified clock() to return total
              	time, user+system.  This is a more commonly needed metric.  I also
              	introduced the new clocku/clocks to get only user/system time if
              	one wants those instead.
              	***WARNING: API CHANGE*** clock() used to return only user time,
              	so if you want exactly the same results as before, use clocku
              	instead.
 -02-22  Ville Vainio  <vivainio@gmail.com>
              	* IPython/Extensions/ipy_p4.py: Extension for improved
                      p4 (perforce version control system) experience.
                      Adds %p4 magic with p4 command completion and
                      automatic -G argument (marshall output as python dict)
 -02-19  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py (Demo.re_stop): make dashes optional in demo
              	stop marks.
              	(ClearingMixin): a simple mixin to easily make a Demo class clear
              	the screen in between blocks and have empty marquees. The
              	ClearDemo and ClearIPDemo classes that use it are included.
 -02-18  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/irunner.py (pexpect_monkeypatch): patch pexpect to
              	protect against exceptions at Python shutdown time.  Patch
              	sumbmitted to upstream.
 -02-14  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: If entering the first object level
              	(i.e. the object for which the browser has been started) fails,
              	now the error is raised directly (aborting the browser) instead of
              	running into an empty levels list later.
 -02-03  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: Add an xrepr implementation
              	for the noitem object.
 -01-31  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/completer.py (Completer.attr_matches): Fix small
              	tab-completion bug with Enthought Traits objects with units.
              	Thanks to a bug report by Tom Denniston
              	<tom.denniston-AT-alum.dartmouth.org>.
 -01-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Extensions/ipy_stock_completers.py (runlistpy): fix a
              	bug where only .ipy or .py would be completed.  Once the first
              	argument to %run has been given, all completions are valid because
              	they are the arguments to the script, which may well be non-python
              	filenames.
              	* IPython/irunner.py (InteractiveRunner.run_source): major updates
              	to irunner to allow it to correctly support real doctesting of
              	out-of-process ipython code.
              	* IPython/Magic.py (magic_cd): Make the setting of the terminal
              	title an option (-noterm_title) because it completely breaks
              	doctesting.
              	* IPython/demo.py: fix IPythonDemo class that was not actually working.
 -01-24  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/irunner.py (main): fix small bug where extensions were
              	not being correctly recognized.
 -01-23  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (xiter): Make sure that iterating
              	a string containing a single line yields the string itself as the
              	only item.
              	* IPython/Extensions/ibrowse.py (ibrowse): Avoid entering an
              	object if it's the same as the one on the last level (This avoids
              	infinite recursion for one line strings).
 -01-17  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ultraTB.py (AutoFormattedTB.__call__): properly flush
              	all output streams before printing tracebacks.  This ensures that
              	user output doesn't end up interleaved with traceback output.
 -01-10  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/envpersist.py: Turbocharged %env that remembers
              	env vars across sessions; e.g. "%env PATH+=;/opt/scripts" or
              	"%env VISUAL=jed".
 -01-05  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (showtraceback): ensure that we correctly call
              	custom handlers in all cases (some with pdb were slipping through,
              	but I'm not exactly sure why).
              	* IPython/Debugger.py (Tracer.__init__): added new class to
              	support set_trace-like usage of IPython's enhanced debugger.
 -12-24  Ville Vainio  <vivainio@gmail.com>
              	* ipmaker.py: more informative message when ipy_user_conf
              	import fails (suggest running %upgrade).
              	* tools/run_ipy_in_profiler.py: Utility to see where
              	the time during IPython startup is spent.
 -12-20  Ville Vainio  <vivainio@gmail.com>
              	* 0.7.3 is out - merge all from 0.7.3 branch to trunk
              	* ipapi.py: Add new ipapi method, expand_alias.
              	* Release.py: Bump up version to 0.7.4.svn
 -12-17  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/jobctrl.py: Fixed &cmd arg arg...
              	to work properly on posix too
              	* Release.py: Update revnum (version is still just 0.7.3).
 -12-15  Ville Vainio  <vivainio@gmail.com>
              	* scripts/ipython_win_post_install: create ipython.py in
              	prefix + "/scripts".
              	* Release.py: Update version to 0.7.3.
 -12-14  Ville Vainio  <vivainio@gmail.com>
              	* scripts/ipython_win_post_install: Overwrite old shortcuts
              	if they already exist
              	* Release.py: release 0.7.3rc2
 -12-13  Ville Vainio  <vivainio@gmail.com>
              	* Branch and update Release.py for 0.7.3rc1
 -12-13  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellWX): update for current WX naming
              	conventions, to avoid a deprecation warning with current WX
              	versions.  Thanks to a report by Danny Shevitz.
 -12-12  Ville Vainio  <vivainio@gmail.com>
              	* ipmaker.py: apply david cournapeau's patch to make
              	import_some work properly even when ipythonrc does
              	import_some on empty list (it was an old bug!).
              	* UserConfig/ipy_user_conf.py, UserConfig/ipythonrc:
              	Add deprecation note to ipythonrc and a url to wiki
              	in ipy_user_conf.py
              	* Magic.py (%run): %run myscript.ipy now runs myscript.ipy
              	as if it was typed on IPython command prompt, i.e.
              	as IPython script.
              	* example-magic.py, magic_grepl.py: remove outdated examples
 -12-11  Fernando Perez  <Fernando.Perez@colorado.edu>
                      * IPython/iplib.py (debugger): prevent a nasty traceback if %debug
                      is called before any exception has occurred.
 -12-08  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipy_stock_completers.py: fix cd completer
              	to translate /'s to \'s again.
              	* completer.py: prevent traceback on file completions w/
              	backslash.
              	* Release.py: Update release number to 0.7.3b3 for release
 -12-07  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipy_signals.py: Ignore ctrl+C in IPython process
              	while executing external code. Provides more shell-like behaviour
              	and overall better response to ctrl + C / ctrl + break.
              	* tools/make_tarball.py: new script to create tarball straight from svn
              	(setup.py sdist doesn't work on win32).
              	* Extensions/ipy_stock_completers.py: fix cd completer to give up
              	on dirnames with spaces and use the default completer instead.
              	* Revision.py: Change version to 0.7.3b2 for release.
 -12-05  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py, iplib.py, completer.py: Apply R. Bernstein's
              	pydb patch 4 (rm debug printing, py 2.5 checking)
 -11-30  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Add two new commands to ibrowse:
              	"refresh" (mapped to "r") refreshes the screen by restarting the iterator.
              	"refreshfind" (mapped to "R") does the same but tries to go back to the same
              	object the cursor was on before the refresh. The command "markrange" is
              	mapped to "%" now.
              	* IPython/Extensions/ibrowse.py: Make igrpentry and ipwdentry comparable.
 -11-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_debug): new %debug magic to activate the
              	interactive debugger on the last traceback, without having to call
              	%pdb and rerun your code.  Made minor changes in various modules,
              	should automatically recognize pydb if available.
 -11-28  Ville Vainio  <vivainio@gmail.com>
              	* completer.py: If the text start with !, show file completions
              	properly. This helps when trying to complete command name
              	for shell escapes.
 -11-27  Ville Vainio  <vivainio@gmail.com>
              	* ipy_stock_completers.py: bzr completer submitted by Stefan van
              	der Walt. Clean up svn and hg completers by using a common
              	vcs_completer.
 -11-26  Ville Vainio  <vivainio@gmail.com>
              	* Remove ipconfig and %config; you should use _ip.options structure
              	directly instead!
              	* genutils.py: add wrap_deprecated function for deprecating callables
              	* iplib.py: deprecate ipmagic, ipsystem, ipalias. Use _ip.magic and
              	_ip.system instead. ipalias is redundant.
              	* Magic.py: %rehashdir no longer aliases 'cmdname' to 'cmdname.exe' on
              	win32, but just 'cmdname'. Other extensions (non-'exe') are still made
              	explicit.
              	* ipy_stock_completers.py: 'hg' (mercurial VCS) now has a custom
              	completer. Try it by entering 'hg ' and pressing tab.
              	* macro.py: Give Macro a useful __repr__ method
              	* Magic.py: %whos abbreviates the typename of Macro for brevity.
 -11-24  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/astyle.py: Do a relative import of ipipe, so that
              	we don't get a duplicate ipipe module, where registration of the xrepr
              	implementation for Text is useless.
              	* IPython/Extensions/ipipe.py: Fix __xrepr__() implementation for ils.
              	* IPython/Extensions/ibrowse.py: Fix keymapping for the enter command.
 -11-24  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py, manual_base.lyx: Kirill Smelkov patch:
              	try to use "cProfile" instead of the slower pure python
              	"profile"
 -11-23  Ville Vainio  <vivainio@gmail.com>
              	* manual_base.lyx: Kirill Smelkov patch: Fix wrong
              	Qt+IPython+Designer link in documentation.
              	* Extensions/ipy_pydb.py: R. Bernstein's patch for passing
              	correct Pdb object to %pydb.
 -11-22  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/astyle.py: Text needs it's own implemenation of the
              	generic xrepr(), otherwise the list implementation would kick in.
 -11-21  Ville Vainio  <vivainio@gmail.com>
              	* upgrade_dir.py: Now actually overwrites a nonmodified user file
              	with one from UserConfig.
              	* ipy_profile_sh.py: Add dummy "depth" to var_expand lambda,
              	it was missing which broke the sh profile.
              	* completer.py: file completer now uses explicit '/' instead
              	of os.path.join, expansion of 'foo' was broken on win32
              	if there was one directory with name 'foobar'.
              	* A bunch of patches from Kirill Smelkov:
              	* [patch 9/9] doc: point bug-tracker URL to IPythons trac-tickets.
              	* [patch 7/9] Implement %page -r (page in raw mode) -
              	* [patch 5/9] ScientificPython webpage has moved
              	* [patch 4/9] The manual mentions %ds, should be %dhist
              	* [patch 3/9] Kill old bits from %prun doc.
              	* [patch 1/9] Fix typos here and there.
 -11-08  Ville Vainio  <vivainio@gmail.com>
              	* completer.py (attr_matches): catch all exceptions raised
              	by eval of expr with dots.
 -11-07  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (runsource): Prepend an 'if 1:' to the user
              	input if it starts with whitespace.  This allows you to paste
              	indented input from any editor without manually having to type in
              	the 'if 1:', which is convenient when working interactively.
              	Slightly modifed version of a patch by Bo Peng
              	<bpeng-AT-rice.edu>.
 -11-03  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/irunner.py (main): modified irunner so it automatically
              	recognizes the right runner to use based on the extension (.py for
              	python, .ipy for ipython and .sage for sage).
              	* IPython/iplib.py (InteractiveShell.ipconfig): new builtin, also
              	visible in ipapi as ip.config(), to programatically control the
              	internal rc object.  There's an accompanying %config magic for
              	interactive use, which has been enhanced to match the
              	funtionality in ipconfig.
              	* IPython/Magic.py (magic_system_verbose): Change %system_verbose
              	so it's not just a toggle, it now takes an argument.  Add support
              	for a customizable header when making system calls, as the new
              	system_header variable in the ipythonrc file.
 -11-03  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: xrepr(), xiter() and xattrs() are now
              	generic functions (using Philip J. Eby's simplegeneric package).
              	This makes it possible to customize the display of third-party classes
              	without having to monkeypatch them. xiter() no longer supports a mode
              	argument and the XMode class has been removed. The same functionality can
              	be implemented via IterAttributeDescriptor and IterMethodDescriptor.
              	One consequence of the switch to generic functions is that xrepr() and
              	xattrs() implementation must define the default value for the mode
              	argument themselves and xattrs() implementations must return real
              	descriptors.
              	* IPython/external: This new subpackage will contain all third-party
              	packages that are bundled with IPython. (The first one is simplegeneric).
              	* IPython/Extensions/ipipe.py (ifile/ils): Readd output of the parent
              	directory which as been dropped in r1703.
              	* IPython/Extensions/ipipe.py (iless): Fixed.
              	* IPython/Extensions/ibrowse: Fixed sorting under Python 2.3.
 -11-03  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.var_expand): fix stack
              	handling in variable expansion so that shells and magics recognize
              	function local scopes correctly.  Bug reported by Brian.
              	* scripts/ipython: remove the very first entry in sys.path which
              	Python auto-inserts for scripts, so that sys.path under IPython is
              	as similar as possible to that under plain Python.
              	* IPython/completer.py (IPCompleter.file_matches): Fix
              	tab-completion so that quotes are not closed unless the completion
              	is unambiguous.  After a request by Stefan.  Minor cleanups in
              	ipy_stock_completers.
 -11-02  Ville Vainio  <vivainio@gmail.com>
              	* ipy_stock_completers.py: Add %run and %cd completers.
              	* completer.py: Try running custom completer for both
              	"foo" and "%foo" if the command is just "foo". Ignore case
              	when filtering possible completions.
              	* UserConfig/ipy_user_conf.py: install stock completers as default
              	* iplib.py (history_saving_wrapper), debugger(), ipy_pydb.py:
              	simplified readline history save / restore through a wrapper
              	function
 -10-31  Ville Vainio  <vivainio@gmail.com>
              	* strdispatch.py, completer.py, ipy_stock_completers.py:
              	Allow str_key ("command") in completer hooks. Implement
              	trivial completer for 'import' (stdlib modules only). Rename
              	ipy_linux_package_managers.py to ipy_stock_completers.py.
              	SVN completer.
              	* Extensions/ledit.py: %magic line editor for easily and
              	incrementally manipulating lists of strings. The magic command
              	name is %led.
 -10-30  Ville Vainio  <vivainio@gmail.com>
              	* Debugger.py, iplib.py (debugger()): Add last set of Rocky
              	Bernsteins's patches for pydb integration.
              	http://bashdb.sourceforge.net/pydb/
              	* strdispatch.py, iplib.py, completer.py, IPython/__init__.py,
              	Extensions/ipy_linux_package_managers.py, hooks.py: Implement
              	custom completer hook to allow the users to implement their own
              	completers. See ipy_linux_package_managers.py for example. The
              	hook name is 'complete_command'.
 -10-28  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/UserConfig/ipythonrc-scipy: minor cleanups to remove old
              	Numeric leftovers.
              	* ipython.el (py-execute-region): apply Stefan's patch to fix
              	garbled results if the python shell hasn't been previously started.
              	* IPython/genutils.py (arg_split): moved to genutils, since it's a
              	pretty generic function and useful for other things.
              	* IPython/OInspect.py (getsource): Add customizable source
              	extractor.  After a request/patch form W. Stein (SAGE).
              	* IPython/irunner.py (InteractiveRunner.run_source): reset tty
              	window size to a more reasonable value from what pexpect does,
              	since their choice causes wrapping bugs with long input lines.
 -10-28  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py (%run): Save and restore the readline history from
              	file around %run commands to prevent side effects from
              	%runned programs that might use readline (e.g. pydb).
              	* extensions/ipy_pydb.py: Adds %pydb magic when imported, for
              	invoking the pydb enhanced debugger.
 -10-23  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (ifile): Remove all methods that
              	call the base class method and propagate the return value to
              	ifile. This is now done by path itself.
 -10-15  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipapi.py (IPApi.__init__): Added new entry to public
              	api: set_crash_handler(), to expose the ability to change the
              	internal crash handler.
              	* IPython/CrashHandler.py (CrashHandler.__init__): abstract out
              	the various parameters of the crash handler so that apps using
              	IPython as their engine can customize crash handling.  Ipmlemented
              	at the request of SAGE.
 -10-14  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py, ipython.el: applied first "safe" part of Rocky
              	Bernstein's patch set for pydb integration.
              	* Magic.py (%unalias, %alias): %store'd aliases can now be
              	removed with '%unalias'. %alias w/o args now shows most
              	interesting (stored / manually defined) aliases last
              	where they catch the eye w/o scrolling.
              	* Magic.py (%rehashx), ext_rehashdir.py: files with
              	'py' extension are always considered executable, even
              	when not in PATHEXT environment variable.
 -10-12  Ville Vainio  <vivainio@gmail.com>
              	* jobctrl.py: Add new "jobctrl" extension for spawning background
              	processes with "&find /". 'import jobctrl' to try it out. Requires
              	'subprocess' module, standard in python 2.4+.
              	* iplib.py (expand_aliases, handle_alias): Aliases expand transitively,
              	so if foo -> bar and bar -> baz, then foo -> baz.
 -10-09  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (Magic.parse_options): add a new posix option
              	to allow parsing of input args in magics that doesn't strip quotes
              	(if posix=False).  This also closes %timeit bug reported by
              	Stefan.
 -10-03  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py (raw_input, interact): Return ValueError catching for
              	raw_input. Fixes infinite loop for sys.stdin.close() or
              	sys.stdout.close().
 -09-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/irunner.py (InteractiveRunner.run_source): small fixes
              	to help in handling doctests.  irunner is now pretty useful for
              	running standalone scripts and simulate a full interactive session
              	in a format that can be then pasted as a doctest.
              	* IPython/iplib.py (InteractiveShell.__init__): Install exit/quit
              	on top of the default (useless) ones.  This also fixes the nasty
              	way in which 2.5's Quitter() exits (reverted [1785]).
              	* IPython/Debugger.py (Pdb.__init__): Fix ipdb to work with python
 .5.
              	* IPython/ultraTB.py (TBTools.set_colors): Make sure that ipdb
              	color scheme is updated as well when color scheme is changed
              	interactively.
 -09-27  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py (raw_input): python 2.5 closes stdin on quit -> avoid
                  infinite loop and just exit. It's a hack, but will do for a while.
 -08-25  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (ils): Add arguments dirs and files to
              	the constructor, this makes it possible to get a list of only directories
              	or only files.
 -08-12  Ville Vainio  <vivainio@gmail.com>
              	* Fakemodule.py, OInspect.py: Reverted 2006-08-11 mods,
              	they broke unittest
 -08-11  Ville Vainio  <vivainio@gmail.com>
              	* Fakemodule.py, OInspect.py: remove 2006-08-09 monkepatch
              	by resolving issue properly, i.e. by inheriting FakeModule
              	from types.ModuleType. Pickling ipython interactive data
              	should still work as usual (testing appreciated).
 -08-09  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/OInspect.py: monkeypatch inspect from the stdlib if
              	running under python 2.3 with code from 2.4 to fix a bug with
              	help().  Reported by the Debian maintainers, Norbert Tretkowski
              	<norbert-AT-tretkowski.de> and Alexandre Fayolle
              	<afayolle-AT-debian.org>.
 -08-04  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Fixed the help message in the footer
              	(which was displaying "quit" twice).
 -07-28  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: Fix isort.__iter__() (was still using
              	the mode argument).
 -07-27  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py: Fix getglobals() if we're
              	not running under IPython.
              	* IPython/Extensions/ipipe.py: Rename XAttr to AttributeDetail
              	and make it iterable (iterating over the attribute itself). Add two new
              	magic strings for __xattrs__(): If the string starts with "-", the attribute
              	will not be displayed in ibrowse's detail view (but it can still be
              	iterated over). This makes it possible to add attributes that are large
              	lists or generator methods to the detail view. Replace magic attribute names
              	and _attrname() and _getattr() with "descriptors": For each type of magic
              	attribute name there's a subclass of Descriptor: None -> SelfDescriptor();
              	"foo" -> AttributeDescriptor("foo"); "foo()" -> MethodDescriptor("foo");
              	"-foo" -> IterAttributeDescriptor("foo"); "-foo()" -> IterMethodDescriptor("foo");
              	foo() -> FunctionDescriptor(foo). Magic strings returned from __xattrs__()
              	are still supported.
              	* IPython/Extensions/ibrowse.py: If fetching the next row from the input
              	fails in ibrowse.fetch(), the exception object is added as the last item
              	and item fetching is canceled. This prevents ibrowse from aborting if e.g.
              	a generator throws an exception midway through execution.
              	* IPython/Extensions/ipipe.py: Turn ifile's properties mimetype and
              	encoding into methods.
 -07-26  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: history now stores multiline input as single
              	history entries. Patch by Jorgen Cederlof.
 -07-18  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Make cursor visible over
              	non existing attributes.
 -07-14  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (ix): Use os.popen4() so that the
              	error output of the running command doesn't mess up the screen.
 -07-13  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (isort): Make isort usable without
              	argument. This sorts the items themselves.
 -07-12  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ipipe.py (eval, ifilter, isort, ieval):
              	Compile expression strings into code objects. This should speed
              	up ifilter and friends somewhat.
 -07-08  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py: %cpaste now strips > from the beginning of lines
              	to ease pasting quoted code from emails. Contributed by
              	Stefan van der Walt.
 -06-29  Ville Vainio  <vivainio@gmail.com>
              	* ipmaker.py, Shell.py: qt4agg matplotlib backend support for pylab
              	mode, patch contributed by Darren Dale. NEEDS TESTING!
 -06-28  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Give the ibrowse cursor row
              	a blue background. Fix fetching new display rows when the browser
              	scrolls more than a screenful (e.g. by using the goto command).
 -06-27  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py (_inspect, _ofind) Apply David Huard's
              	patch for displaying the correct docstring for 'property'
              	attributes.
 -06-23  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Put the documentation of the keyboard
              	commands into the methods implementing them.
 -06-22  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* ipython.el (ipython-indentation-hook): cleanup patch, submitted
              	by Kov Chai <tchaikov-AT-gmail.com>.  He notes that the original
              	autoindent support was authored by Jin Liu.
 -06-22  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Replace the plain dictionaries used
              	for keymaps with a custom class that simplifies handling.
 -06-19  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: ibrowse now properly handles terminal
              	resizing. This requires Python 2.5 to work.
 -06-16  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Add two new commands to
              	ibrowse: "hideattr" (mapped to "h") hides the attribute under
              	the cursor. "unhiderattrs" (mapped to "H") reveals all hidden
              	attributes again. Remapped the help command to "?". Display
              	keycodes in the range 0x01-0x1F as CTRL-xx. Add CTRL-a and CTRL-e
              	as keys for the "home" and "end" commands. Add three new commands
              	to the input mode for "find" and friends: "delend" (CTRL-K)
              	deletes to the end of line. "incsearchup" searches upwards in the
              	command history for an input that starts with the text before the cursor.
              	"incsearchdown" does the same downwards. Removed a bogus mapping of
              	the x key to "delete".
 -06-15  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py, hooks.py: Added new generate_prompt hook that can be
              	used to create prompts dynamically, instead of the "old" way of
              	assigning "magic" strings to prompt_in1 and prompt_in2. The old
              	way still works (it's invoked by the default hook), of course.
              	* Prompts.py: added generate_output_prompt hook for altering output
              	prompt
              	* Release.py: Changed version string to 0.7.3.svn.
 -06-15  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Change _BrowserLevel.moveto() so that
              	the call to fetch() always tries to fetch enough data for at least one
              	full screen. This makes it possible to simply call moveto(0,0,True) in
              	the constructor. Fix typos and removed the obsolete goto attribute.
 -06-12  Ville Vainio  <vivainio@gmail.com>
              	* ipy_profile_sh.py: applied Krisha Mohan Gundu's patch for
              	allowing $variable interpolation within multiline statements,
              	though so far only with "sh" profile for a testing period.
              	The patch also enables splitting long commands with \ but it
              	doesn't work properly yet.
 -06-12  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py (_dodisplay): Display the length of the
              	input history and the position of the cursor in the input history for
              	the find, findbackwards and goto command.
 -06-10  Walter Doerwald  <walter@livinglogic.de>
              	* IPython/Extensions/ibrowse.py: Add a class _CommandInput that
              	implements the basic functionality of browser commands that require
              	input. Reimplement the goto, find and findbackwards commands as
              	subclasses of _CommandInput. Add an input history and keymaps to those
              	commands. Add "\r" as a keyboard shortcut for the enterdefault and
              	execute commands.
 -06-07  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: ipython mybatch.ipy exits ipython immediately after
              	running the batch files instead of leaving the session open.
 -06-07  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): update BSD fix, as
              	the original fix was incomplete.  Patch submitted by W. Maier.
 -06-07  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py,Magic.py, ipmaker.py (magic_rehashx):
              	Confirmation prompts can be supressed by 'quiet' option.
              	_ip.options.quiet = 1 means "assume yes for all yes/no queries".
 -06-06  *** Released version 0.7.2
 -06-06  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Release.py (version): Made 0.7.2 final for release.
              	Repo tagged and release cut.
 -06-05  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py (magic_rehashx): Honor no_alias list earlier in
              	%rehashx, to avoid clobbering builtins in ipy_profile_sh.py
              	* upgrade_dir.py: try import 'path' module a bit harder
              	(for %upgrade)
 -06-03  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/genutils.py (ask_yes_no): treat EOF as a default answer
              	instead of looping 20 times.
              	* IPython/ipmaker.py (make_IPython): honor -ipythondir flag
              	correctly at initialization time.  Bug reported by Krishna Mohan
              	Gundu <gkmohan-AT-gmail.com> on the user list.
              	* IPython/Release.py (version): Mark 0.7.2 version to start
              	testing for release on 06/06.
 -05-31  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* scripts/irunner: thin script interface so users don't have to
              	find the module and call it as an executable, since modules rarely
              	live in people's PATH.
              	* IPython/irunner.py (InteractiveRunner.__init__): added
              	delaybeforesend attribute to control delays with newer versions of
              	pexpect.  Thanks to detailed help from pexpect's author, Noah
              	Spurrier <noah-AT-noah.org>.  Noted how to use the SAGE runner
              	correctly (it works in NoColor mode).
              	* IPython/iplib.py (handle_normal): fix nasty crash reported on
              	SAGE list, from improper log() calls.
 -05-31  Ville Vainio  <vivainio@gmail.com>
              	* upgrade_dir.py, Magic.py (magic_upgrade): call upgrade_dir
              	with args in parens to work correctly with dirs that have spaces.
 -05-30  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Logger.py (Logger.logstart): add option to log raw input
              	instead of the processed one.  A -r flag was added to the
              	%logstart magic used for controlling logging.
 -05-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): add check for the
              	*BSDs to omit --color from all 'ls' aliases, since *BSD ls doesn't
              	recognize the option.  After a bug report by Will Maier.  This
              	closes #64 (will do it after confirmation from W. Maier).
              	* IPython/irunner.py: New module to run scripts as if manually
              	typed into an interactive environment, based on pexpect.  After a
              	submission by Ken Schutte <kschutte-AT-csail.mit.edu> on the
              	ipython-user list.  Simple unittests in the tests/ directory.
              	* tools/release: add Will Maier, OpenBSD port maintainer, to
              	recepients list.  We are now officially part of the OpenBSD ports:
              	http://www.openbsd.org/ports.html !  Many thanks to Will for the
              	work.
 -05-26  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): modify sys.argv fix (below)
              	so that it doesn't break tkinter apps.
              	* IPython/iplib.py (_prefilter): fix bug where aliases would
              	shadow variables when autocall was fully off.  Reported by SAGE
              	author William Stein.
              	* IPython/OInspect.py (Inspector.__init__): add a flag to control
              	at what detail level strings are computed when foo? is requested.
              	This allows users to ask for example that the string form of an
              	object is only computed when foo?? is called, or even never, by
              	setting the object_info_string_level >= 2 in the configuration
              	file.  This new option has been added and documented.  After a
              	request by SAGE to be able to control the printing of very large
              	objects more easily.
 -05-25  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): remove the ipython call path
              	from sys.argv, to be 100% consistent with how Python itself works
              	(as seen for example with python -i file.py).  After a bug report
              	by Jeffrey Collins.
              	* IPython/Shell.py (MatplotlibShellBase._matplotlib_config): Fix
              	nasty bug which was preventing custom namespaces with -pylab,
              	reported by M. Foord.  Minor cleanup, remove old matplotlib.matlab
              	compatibility (long gone from mpl).
              	* IPython/ipapi.py (make_session): name change: create->make.  We
              	use make in other places (ipmaker,...), it's shorter and easier to
              	type and say, etc.  I'm trying to clean things before 0.7.2 so
              	that I can keep things stable wrt to ipapi in the chainsaw branch.
              	* ipython.el: fix the py-pdbtrack-input-prompt variable so that
              	python-mode recognizes our debugger mode.  Add support for
              	autoindent inside (X)emacs.  After a patch sent in by Jin Liu
              	<m.liu.jin-AT-gmail.com> originally written by
              	doxgen-AT-newsmth.net (with minor modifications for xemacs
              	compatibility)
              	* IPython/Debugger.py (Pdb.format_stack_entry): fix formatting of
              	tracebacks when walking the stack so that the stack tracking system
              	in emacs' python-mode can identify the frames correctly.
              	* IPython/ipmaker.py (make_IPython): make the internal (and
              	default config) autoedit_syntax value false by default.  Too many
              	users have complained to me (both on and off-list) about problems
              	with this option being on by default, so I'm making it default to
              	off.  It can still be enabled by anyone via the usual mechanisms.
              	* IPython/completer.py (Completer.attr_matches): add support for
              	PyCrust-style _getAttributeNames magic method.  Patch contributed
              	by <mscott-AT-goldenspud.com>.  Closes #50.
              	* IPython/iplib.py (InteractiveShell.__init__): remove the
              	deletion of exit/quit from __builtin__, which can break
              	third-party tools like the Zope debugging console.  The
              	%exit/%quit magics remain.  In general, it's probably a good idea
              	not to delete anything from __builtin__, since we never know what
              	that will break.  In any case, python now (for 2.5) will support
              	'real' exit/quit, so this issue is moot.  Closes #55.
              	* IPython/genutils.py (with_obj): rename the 'with' function to
              	'withobj' to avoid incompatibilities with Python 2.5, where 'with'
              	becomes a language keyword.  Closes #53.
              	* IPython/FakeModule.py (FakeModule.__init__): add a proper
              	__file__ attribute to this so it fools more things into thinking
              	it is a real module.  Closes #59.
              	* IPython/Magic.py (magic_edit): add -n option to open the editor
              	at a specific line number.  After a patch by Stefan van der Walt.
 -05-23  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (edit_syntax_error): fix crash when for some
              	reason the file could not be opened.  After automatic crash
              	reports sent by James Graham <jgraham-AT-ast.cam.ac.uk> and
              	Charles Dolan <charlespatrickdolan-AT-yahoo.com>.
              	(_should_recompile): Don't fire editor if using %bg, since there
              	is no file in the first place.  From the same report as above.
              	(raw_input): protect against faulty third-party prefilters.  After
              	an automatic crash report sent by Dirk Laurie <dirk-AT-sun.ac.za>
              	while running under SAGE.
 -05-23  Ville Vainio  <vivainio@gmail.com>
              	* ipapi.py: Stripped down ip.to_user_ns() to work only as
              	ip.to_user_ns("x1 y1"), which exposes vars x1 and y1. ipapi.get()
              	now returns None (again), unless dummy is specifically allowed by
              	ipapi.get(allow_dummy=True).
 -05-18  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython: remove all 2.2-compatibility objects and hacks from
              	everywhere, since we only support 2.3 at this point.  Docs
              	updated.
              	* IPython/ipapi.py (IPApi.__init__): Cleanup of all getters.
              	Anything requiring extra validation can be turned into a Python
              	property in the future.  I used a property for the db one b/c
              	there was a nasty circularity problem with the initialization
              	order, which right now I don't have time to clean up.
              	* IPython/Shell.py (MTInteractiveShell.runcode): Fix, I think,
              	another locking bug reported by Jorgen.  I'm not 100% sure though,
              	so more testing is needed...
 -05-17  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipapi.py (IPApi.to_user_ns): New function to inject
              	local variables from any routine in user code (typically executed
              	with %run) directly into the interactive namespace.  Very useful
              	when doing complex debugging.
              	(IPythonNotRunning): Changed the default None object to a dummy
              	whose attributes can be queried as well as called without
              	exploding, to ease writing code which works transparently both in
              	and out of ipython and uses some of this API.
 -05-16  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/hooks.py (result_display): Fix the fact that our display
              	hook was using str() instead of repr(), as the default python
              	console does.  This had gone unnoticed b/c it only happened if
              	%Pprint was off, but the inconsistency was there.
 -05-15  Ville Vainio  <vivainio@gmail.com>
              	* Oinspect.py: Only show docstring for nonexisting/binary files
              	when doing object??, closing ticket #62
 -05-13  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (MTInteractiveShell.runsource): Fix threading
              	bug, closes http://www.scipy.net/roundup/ipython/issue55.  A lock
              	was being released in a routine which hadn't checked if it had
              	been the one to acquire it.
 -05-07  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Release.py (version): put out 0.7.2.rc1 for testing.
 -04-11  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py, ipmaker.py: .ipy extension now means "ipython batch file"
              	in command line. E.g. "ipython test.ipy" runs test.ipy with ipython
              	prefilters, allowing stuff like magics and aliases in the file.
              	* Prompts.py, Extensions/clearcmd.py, ipy_system_conf.py: %clear magic
              	added. Supported now are "%clear in" and "%clear out" (clear input and
              	output history, respectively). Also fixed CachedOutput.flush to
              	properly flush the output cache.
              	* Extensions/pspersistence.py: Fix %store to avoid "%store obj.attr"
              	half-success (and fail explicitly).
 -03-28  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: Fix quoting of aliases so that only argless ones
              	are quoted
 -03-28  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: Quote aliases with spaces in the name.
              	"c:\program files\blah\bin" is now legal alias target.
              	* ext_rehashdir.py: Space no longer allowed as arg
              	separator, since space is legal in path names.
 -03-16  Ville Vainio  <vivainio@gmail.com>
              	* upgrade_dir.py: Take path.py from Extensions, correcting
              	%upgrade magic
              	* ipmaker.py: Suggest using %upgrade if ipy_user_conf.py isn't found.
              	* hooks.py: Only enclose editor binary in quotes if legal and
              	necessary (space in the name, and is an existing file). Fixes a bug
              	reported by Zachary Pincus.
 -03-13  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* Manual: thanks to a tip on proper color handling for Emacs, by
              	Eric J Haywiser <ejh1-AT-MIT.EDU>.
              	* ipython.el: close http://www.scipy.net/roundup/ipython/issue57
              	by applying the provided patch.  Thanks to Liu Jin
              	<m.liu.jin-AT-gmail.com> for the contribution.  No problems under
              	XEmacs/Linux, I'm trusting the submitter that it actually helps
              	under win32/GNU Emacs.  Will revisit if any problems are reported.
 -03-12  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Gnuplot2.py (_FileClass): update for current Gnuplot.py
              	from SVN, thanks to a patch by Ryan Woodard <rywo@bas.ac.uk>.
 -03-12  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py (magic_timeit): Added %timeit magic, contributed by
              	Torsten Marek.
 -03-12  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_macro): fix so that the n1-n2 syntax for
              	line ranges works again.
 -03-11  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (showtraceback): add back sys.last_traceback
              	and friends, after a discussion with Zach Pincus on ipython-user.
              	I'm not 100% sure, but after thinking about it quite a bit, it may
              	be OK.  Testing with the multithreaded shells didn't reveal any
              	problems, but let's keep an eye out.
              	In the process, I fixed a few things which were calling
              	self.InteractiveTB() directly (like safe_execfile), which is a
              	mistake: ALL exception reporting should be done by calling
              	self.showtraceback(), which handles state and tab-completion and
              	more.
 -03-01  Ville Vainio  <vivainio@gmail.com>
              	* Extensions/ipipe.py: Added Walter Doerwald's "ipipe" module.
              	To use, do "from ipipe import *".
 -02-24  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py, upgrade_dir.py: %upgrade magic added. Does things more
              	"cleanly" and safely than the older upgrade mechanism.
 -02-21  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py: %save works again.
 -02-15  Ville Vainio  <vivainio@gmail.com>
              	* Magic.py: %Pprint works again
              	* Extensions/ipy_sane_defaults.py: Provide everything provided
              	in default ipythonrc, to make it possible to have a completely empty
              	ipythonrc (and thus completely rc-file free configuration)
 -02-11  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/hooks.py (editor): quote the call to the editor command,
              	to allow commands with spaces in them.  Problem noted by watching
              	Ian Oswald's video about textpad under win32 at
              	http://showmedo.com/videoListPage?listKey=PythonIPythonSeries
              	* IPython/UserConfig/ipythonrc: Replace @ signs with % when
              	describing magics (we haven't used @ for a loong time).
              	* IPython/ultraTB.py (VerboseTB.text.text_repr): Added patch
              	contributed by marienz to close
              	http://www.scipy.net/roundup/ipython/issue53.
 -02-10  Ville Vainio  <vivainio@gmail.com>
              	* genutils.py: getoutput now works in win32 too
              	* completer.py: alias and magic completion only invoked
              	at the first "item" in the line, to avoid "cd %store"
              	nonsense.
 -02-09  Ville Vainio  <vivainio@gmail.com>
              	* test/*: Added a unit testing framework (finally).
              	'%run runtests.py' to run test_*.
              	* ipapi.py: Exposed runlines and set_custom_exc
 -02-07  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: don't split "f 1 2" to "f(1,2)" in autocall,
              	instead use "f(1 2)" as before.
 -02-05  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py (IPythonDemo): Add new classes to the demo
              	facilities, for demos processed by the IPython input filter
              	(IPythonDemo), and for running a script one-line-at-a-time as a
              	demo, both for pure Python (LineDemo) and for IPython-processed
              	input (IPythonLineDemo).  After a request by Dave Kohel, from the
              	SAGE team.
              	(Demo.edit): added an edit() method to the demo objects, to edit
              	the in-memory copy of the last executed block.
              	* IPython/Magic.py (magic_edit): add '-r' option for 'raw'
              	processing to %edit, %macro and %save.  These commands can now be
              	invoked on the unprocessed input as it was typed by the user
              	(without any prefilters applied).  After requests by the SAGE team
              	at SAGE days 2006: http://modular.ucsd.edu/sage/days1/schedule.html.
 -02-01  Ville Vainio  <vivainio@gmail.com>
              	* setup.py, eggsetup.py: easy_install ipython==dev works
              	correctly now (on Linux)
              	* ipy_user_conf,ipmaker: user config changes, removed spurious
              	warnings
              	* iplib: if rc.banner is string, use it as is.
              	* Magic: %pycat accepts a string argument and pages it's contents.
 -01-30  Ville Vainio  <vivainio@gmail.com>
              	* pickleshare,pspersistence,ipapi,Magic: persistence overhaul.
              	Now %store and bookmarks work through PickleShare, meaning that
              	concurrent access is possible and all ipython sessions see the
              	same database situation all the time, instead of snapshot of
              	the situation when the session was started. Hence, %bookmark
              	results are immediately accessible from othes sessions. The database
              	is also available for use by user extensions. See:
              	http://www.python.org/pypi/pickleshare
              	* hooks.py: Two new hooks, 'shutdown_hook' and 'late_startup_hook'.
              	* aliases can now be %store'd
              	* path.py moved to Extensions so that pickleshare does not need
              	IPython-specific import. Extensions added to pythonpath right
              	at __init__.
              	* iplib.py: ipalias deprecated/redundant; aliases are converted and
              	called with _ip.system and the pre-transformed command string.
 -01-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (interact): Fix that we were not catching
              	KeyboardInterrupt exceptions properly.  I'm not quite sure why the
              	logic here had to change, but it's fixed now.
 -01-29  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: Try to import pyreadline on Windows.
 -01-27  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py: Expose ipapi as _ip in builtin namespace.
              	Makes ipmagic (-> _ip.magic), ipsystem (-> _ip.system)
              	and ip_set_hook (-> _ip.set_hook) redundant. % and !
              	syntax now produce _ip.* variant of the commands.
              	* "_ip.options().autoedit_syntax = 2" automatically throws
              	user to editor for syntax error correction without prompting.
 -01-27  Ville Vainio  <vivainio@gmail.com>
              	* ipmaker.py: Give "realistic" sys.argv for scripts (without
              	'ipython' at argv[0]) executed through command line.
              	NOTE: this DEPRECATES calling ipython with multiple scripts
              	("ipython a.py b.py c.py")
              	* iplib.py, hooks.py: Added configurable input prefilter,
              	named 'input_prefilter'. See ext_rescapture.py for example
              	usage.
              	* ext_rescapture.py, Magic.py: Better system command output capture
              	through 'var = !ls' (deprecates user-visible %sc). Same notation
              	applies for magics, 'var = %alias' assigns alias list to var.
              	* ipapi.py: added meta() for accessing extension-usable data store.
              	* iplib.py: added InteractiveShell.getapi(). New magics should be
              	written doing self.getapi() instead of using the shell directly.
              	* Magic.py: %store now allows doing %store foo > ~/myfoo.txt and
              	%store foo >> ~/myfoo.txt to store variables to files (in clean
              	textual form, not a restorable pickle).
              	* ipmaker.py: now import ipy_profile_PROFILENAME automatically
              	* usage.py, Magic.py: added %quickref
              	* iplib.py: ESC_PAREN fixes: /f 1 2 -> f(1,2), not f(1 2).
              	* GetoptErrors when invoking magics etc. with wrong args
              	are now more helpful:
              	GetoptError: option -l not recognized (allowed: "qb" )
 -01-25  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py (Demo.show): Flush stdout after each block, so
              	computationally intensive blocks don't appear to stall the demo.
 -01-24  Ville Vainio  <vivainio@gmail.com>
              	* iplib.py, hooks.py: 'result_display' hook can return a non-None
              	value to manipulate resulting history entry.
              	* ipapi.py: Moved TryNext here from hooks.py. Moved functions
              	to instance methods of IPApi class, to make extending an embedded
              	IPython feasible. See ext_rehashdir.py for example usage.
              	* Merged 1071-1076 from branches/0.7.1
 -01-23  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* tools/release (daystamp): Fix build tools to use the new
              	eggsetup.py script to build lightweight eggs.
              	* Applied changesets 1062 and 1064 before 0.7.1 release.
              	* IPython/Magic.py (magic_history): Add '-r' option to %hist, to
              	see the raw input history (without conversions like %ls ->
              	ipmagic("ls")).  After a request from W. Stein, SAGE
              	(http://modular.ucsd.edu/sage) developer.  This information is
              	stored in the input_hist_raw attribute of the IPython instance, so
              	developers can access it if needed (it's an InputList instance).
              	* Versionstring = 0.7.2.svn
              	* eggsetup.py: A separate script for constructing eggs, creates
              	proper launch scripts even on Windows (an .exe file in
              	\python24\scripts).
              	* ipapi.py: launch_new_instance, launch entry point needed for the
              	egg.
 -01-23  Ville Vainio  <vivainio@gmail.com>
              	* Added %cpaste magic for pasting python code
 -01-22  Ville Vainio  <vivainio@gmail.com>
              	* Merge from branches/0.7.1 into trunk, revs 1052-1057
              	* Versionstring = 0.7.2.svn
              	* eggsetup.py: A separate script for constructing eggs, creates
              	proper launch scripts even on Windows (an .exe file in
              	\python24\scripts).
              	* ipapi.py: launch_new_instance, launch entry point needed for the
              	egg.
 -01-22  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/OInspect.py (Inspector.pinfo): fix bug where foo?? or
              	%pfile foo would print the file for foo even if it was a binary.
              	Now, extensions '.so' and '.dll' are skipped.
              	* IPython/Shell.py (MTInteractiveShell.__init__): Fix threading
              	bug, where macros would fail in all threaded modes.  I'm not 100%
              	sure, so I'm going to put out an rc instead of making a release
              	today, and wait for feedback for at least a few days.
              	* IPython/iplib.py (handle_normal): fix (finally? somehow I doubt
              	it...) the handling of pasting external code with autoindent on.
              	To get out of a multiline input, the rule will appear for most
              	users unchanged: two blank lines or change the indent level
              	proposed by IPython.  But there is a twist now: you can
              	add/subtract only *one or two spaces*.  If you add/subtract three
              	or more (unless you completely delete the line), IPython will
              	accept that line, and you'll need to enter a second one of pure
              	whitespace.  I know it sounds complicated, but I can't find a
              	different solution that covers all the cases, with the right
              	heuristics.  Hopefully in actual use, nobody will really notice
              	all these strange rules and things will 'just work'.

              	* IPython/iplib.py (interact): catch exceptions which can be
              	triggered asynchronously by signal handlers.  Thanks to an
              	automatic crash report, submitted by Colin Kingsley
              	<tercel-AT-gentoo.org>.
 -01-20  Ville Vainio  <vivainio@gmail.com>
              	* Ipython/Extensions/ext_rehashdir.py: Created a usable example
              	(%rehashdir, very useful, try it out) of how to extend ipython
              	with new magics. Also added Extensions dir to pythonpath to make
              	importing extensions easy.
              	* %store now complains when trying to store interactively declared
              	classes / instances of those classes.
              	* Extensions/ipy_system_conf.py, UserConfig/ipy_user_conf.py,
              	ipmaker.py: Config rehaul. Now ipy_..._conf.py are always imported
              	if they exist, and ipy_user_conf.py with some defaults is created for
              	the user.
              	* Startup rehashing done by the config file, not InterpreterExec.
              	This means system commands are available even without selecting the
              	pysh profile. It's the sensible default after all.
 -01-20  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (raw_input): I _think_ I got the pasting of
              	multiline code with autoindent on working.  But I am really not
              	sure, so this needs more testing.  Will commit a debug-enabled
              	version for now, while I test it some more, so that Ville and
              	others may also catch any problems.  Also made
              	self.indent_current_str() a method, to ensure that there's no
              	chance of the indent space count and the corresponding string
              	falling out of sync.  All code needing the string should just call
              	the method.
 -01-18  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_edit): fix check for when users don't
              	save their output files, the try/except was in the wrong section.
 -01-17  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_run): fix __file__ global missing from
              	script's namespace when executed via %run.  After a report by
              	Vivian.
              	* IPython/Debugger.py (Pdb.__init__): Fix breakage with '%run -d'
              	when using python 2.4.  The parent constructor changed in 2.4, and
              	we need to track it directly (we can't call it, as it messes up
              	readline and tab-completion inside our pdb would stop working).
              	After a bug report by R. Bernstein <rocky-AT-panix.com>.
 -01-16  Ville Vainio  <vivainio@gmail.com>
              	* Ipython/magic.py: Reverted back to old %edit functionality
              	that returns file contents on exit.
              	* IPython/path.py: Added Jason Orendorff's "path" module to
              	IPython tree, http://www.jorendorff.com/articles/python/path/.
              	You can get path objects conveniently through %sc, and !!, e.g.:
              	 sc files=ls
              	 for p in files.paths: # or files.p
              	     print p,p.mtime
              	* Ipython/iplib.py:"," and ";" autoquoting-upon-autocall
              	now work again without considering the exclusion regexp -
              	hence, things like ',foo my/path' turn to 'foo("my/path")'
              	instead of syntax error.
 -01-14  Ville Vainio  <vivainio@gmail.com>
              	* IPython/ipapi.py (ashook, asmagic, options): Added convenience
              	ipapi decorators for python 2.4 users, options() provides access to rc
              	data.
              	* IPython/Magic.py (magic_cd): %cd now accepts backslashes
              	as path separators (even on Linux ;-). Space character after
              	backslash (as yielded by tab completer) is still space;
              	"%cd long\ name" works as expected.
              	* IPython/ipapi.py,hooks.py,iplib.py: Hooks now implemented
              	as "chain of command", with priority. API stays the same,
              	TryNext exception raised by a hook function signals that
              	current hook failed and next hook should try handling it, as
              	suggested by Walter Dörwald <walter@livinglogic.de>. Walter also
              	requested configurable display hook, which is now implemented.
 -01-13  Ville Vainio  <vivainio@gmail.com>
              	* IPython/platutils*.py: platform specific utility functions,
              	so far only set_term_title is implemented (change terminal
              	label in windowing systems). %cd now changes the title to
              	current dir.
              	* IPython/Release.py: Added myself to "authors" list,
              	had to create new files.
              	* IPython/iplib.py (handle_shell_escape): fixed logical flaw in
              	shell escape; not a known bug but had potential to be one in the
              	future.
              	* IPython/ipapi.py (added),OInspect.py,iplib.py: "Public"
              	extension API for IPython! See the module for usage example. Fix
              	OInspect for docstring-less magic functions.
 -01-13  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (raw_input): temporarily deactivate all
              	attempts at allowing pasting of code with autoindent on.  It
              	introduced bugs (reported by Prabhu) and I can't seem to find a
              	robust combination which works in all cases.  Will have to revisit
              	later.
              	* IPython/genutils.py: remove isspace() function.  We've dropped
 .2 compatibility, so it's OK to use the string method.
 -01-12  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): fix regexp
              	matching what NOT to autocall on, to include all python binary
              	operators (including things like 'and', 'or', 'is' and 'in').
              	Prompted by a bug report on 'foo & bar', but I realized we had
              	many more potential bug cases with other operators.  The regexp is
              	self.re_exclude_auto, it's fairly commented.
 -01-12  Ville Vainio  <vivainio@gmail.com>
              	* IPython/iplib.py (make_quoted_expr,handle_shell_escape):
              	Prettified and hardened string/backslash quoting with ipsystem(),
              	ipalias() and ipmagic(). Now even \ characters are passed to
              	%magics, !shell escapes and aliases exactly as they are in the
              	ipython command line. Should improve backslash experience,
              	particularly in Windows (path delimiter for some commands that
              	won't understand '/'), but Unix benefits as well (regexps). %cd
              	magic still doesn't support backslash path delimiters, though. Also
              	deleted all pretense of supporting multiline command strings in
              	!system or %magic commands. Thanks to Jerry McRae for suggestions.
              	* doc/build_doc_instructions.txt added. Documentation on how to
              	use doc/update_manual.py, added yesterday. Both files contributed
              	by Jörgen Stenarson <jorgen.stenarson-AT-bostream.nu>. This slates
              	doc/*.sh for deprecation at a later date.
              	* /ipython.py Added ipython.py to root directory for
              	zero-installation (tar xzvf ipython.tgz; cd ipython; python
              	ipython.py) and development convenience (no need to keep doing
              	"setup.py install" between changes).
              	* Made ! and !! shell escapes work (again) in multiline expressions:
              	  if 1:
              	      !ls
              	      !!ls
 -01-12  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipstruct.py (Struct): Rename IPython.Struct to
              	IPython.ipstruct, to avoid local shadowing of the stdlib 'struct'
              	module in case-insensitive installation.  Was causing crashes
              	under win32.  Closes http://www.scipy.net/roundup/ipython/issue49.
              	* IPython/Magic.py (magic_pycat): Fix pycat, patch by Marien Zwart
              	<marienz-AT-gentoo.org>, closes
              	http://www.scipy.net/roundup/ipython/issue51.
 -01-11  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.on_timer): Finally fix the
              	problem of excessive CPU usage under *nix and keyboard lag under
              	win32.
 -01-10  *** Released version 0.7.0
 -01-10  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Release.py (revision): tag version number to 0.7.0,
              	ready for release.
              	* IPython/Magic.py (magic_edit): Add print statement to %edit so
              	it informs the user of the name of the temp. file used.  This can
              	help if you decide later to reuse that same file, so you know
              	where to copy the info from.
 -01-09  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* setup_bdist_egg.py: little script to build an egg.  Added
              	support in the release tools as well.
 -01-08  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellWX.__init__): add support for WXPython
              	version selection (new -wxversion command line and ipythonrc
              	parameter).  Patch contributed by Arnd Baecker
              	<arnd.baecker-AT-web.de>.
              	* IPython/iplib.py (embed_mainloop): fix tab-completion in
              	embedded instances, for variables defined at the interactive
              	prompt of the embedded ipython.  Reported by Arnd.
              	* IPython/Magic.py (magic_autocall): Fix %autocall magic.  Now
              	it can be used as a (stateful) toggle, or with a direct parameter.
              	* IPython/ultraTB.py (_fixed_getinnerframes): remove debug assert which
              	could be triggered in certain cases and cause the traceback
              	printer not to work.
 -01-07  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (_should_recompile): Small fix, closes
              	http://www.scipy.net/roundup/ipython/issue48.  Patch by Scott.
 -01-04  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): fix bug in the GTK
              	backend for matplotlib (100% cpu utiliziation).  Thanks to Charlie
              	Moad for help with tracking it down.
              	* IPython/iplib.py (handle_auto): fix autocall handling for
              	objects which support BOTH __getitem__ and __call__ (so that f [x]
              	is left alone, instead of becoming f([x]) automatically).
              	* IPython/Magic.py (magic_cd): fix crash when cd -b was used.
              	Ville's patch.
 -01-03  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (handle_auto): changed autocall semantics to
              	include 'smart' mode, where the autocall transformation is NOT
              	applied if there are no arguments on the line.  This allows you to
              	just type 'foo' if foo is a callable to see its internal form,
              	instead of having it called with no arguments (typically a
              	mistake).  The old 'full' autocall still exists: for that, you
              	need to set the 'autocall' parameter to 2 in your ipythonrc file.
              	* IPython/completer.py (Completer.attr_matches): add
              	tab-completion support for Enthoughts' traits.  After a report by
              	Arnd and a patch by Prabhu.
 -01-02  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ultraTB.py (_fixed_getinnerframes): added Alex
              	Schmolck's patch to fix inspect.getinnerframes().
              	* IPython/iplib.py (InteractiveShell.__init__): significant fixes
              	for embedded instances, regarding handling of namespaces and items
              	added to the __builtin__ one.  Multiple embedded instances and
              	recursive embeddings should work better now (though I'm not sure
              	I've got all the corner cases fixed, that code is a bit of a brain
              	twister).
              	* IPython/Magic.py (magic_edit): added support to edit in-memory
              	macros (automatically creates the necessary temp files).  %edit
              	also doesn't return the file contents anymore, it's just noise.
              	* IPython/completer.py (Completer.attr_matches): revert change to
              	complete only on attributes listed in __all__.  I realized it
              	cripples the tab-completion system as a tool for exploring the
              	internals of unknown libraries (it renders any non-__all__
              	attribute off-limits).  I got bit by this when trying to see
              	something inside the dis module.
 -12-31  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): add .meta
              	namespace for users and extension writers to hold data in.  This
              	follows the discussion in
              	http://projects.scipy.org/ipython/ipython/wiki/RefactoringIPython.
              	* IPython/completer.py (IPCompleter.complete): small patch to help
              	tab-completion under Emacs, after a suggestion by John Barnard
              	<barnarj-AT-ccf.org>.
              	* IPython/Magic.py (Magic.extract_input_slices): added support for
              	the slice notation in magics to use N-M to represent numbers N...M
              	(closed endpoints).  This is used by %macro and %save.
              	* IPython/completer.py (Completer.attr_matches): for modules which
              	define __all__, complete only on those.  After a patch by Jeffrey
              	Collins <jcollins_boulder-AT-earthlink.net>.  Also, clean up and
              	speed up this routine.
              	* IPython/Logger.py (Logger.log): fix a history handling bug.  I
              	don't know if this is the end of it, but the behavior now is
              	certainly much more correct.  Note that coupled with macros,
              	slightly surprising (at first) behavior may occur: a macro will in
              	general expand to multiple lines of input, so upon exiting, the
              	in/out counters will both be bumped by the corresponding amount
              	(as if the macro's contents had been typed interactively).  Typing
              	%hist will reveal the intermediate (silently processed) lines.
              	* IPython/Magic.py (magic_run): fix a subtle bug which could cause
              	pickle to fail (%run was overwriting __main__ and not restoring
              	it, but pickle relies on __main__ to operate).
              	* IPython/iplib.py (InteractiveShell): fix pdb calling: I'm now
              	using properties, but forgot to make the main InteractiveShell
              	class a new-style class.  Properties fail silently, and
              	mysteriously, with old-style class (getters work, but
              	setters don't do anything).
 -12-30  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_history): fix history reporting bug (I
              	know some nasties are still there, I just can't seem to find a
              	reproducible test case to track them down; the input history is
              	falling out of sync...)
              	* IPython/iplib.py (handle_shell_escape): fix bug where both
              	aliases and system accesses where broken for indented code (such
              	as loops).
              	* IPython/genutils.py (shell): fix small but critical bug for
              	win32 system access.
 -12-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (showtraceback): remove use of the
              	sys.last_{type/value/traceback} structures, which are non
              	thread-safe.
              	(_prefilter): change control flow to ensure that we NEVER
              	introspect objects when autocall is off.  This will guarantee that
              	having an input line of the form 'x.y', where access to attribute
              	'y' has side effects, doesn't trigger the side effect TWICE.  It
              	is important to note that, with autocall on, these side effects
              	can still happen.
              	(ipsystem): new builtin, to complete the ip{magic/alias/system}
              	trio.  IPython offers these three kinds of special calls which are
              	not python code, and it's a good thing to have their call method
              	be accessible as pure python functions (not just special syntax at
              	the command line).  It gives us a better internal implementation
              	structure, as well as exposing these for user scripting more
              	cleanly.
              	* IPython/macro.py (Macro.__init__): moved macros to a standalone
              	file.  Now that they'll be more likely to be used with the
              	persistance system (%store), I want to make sure their module path
              	doesn't change in the future, so that we don't break things for
              	users' persisted data.
              	* IPython/iplib.py (autoindent_update): move indentation
              	management into the _text_ processing loop, not the keyboard
              	interactive one.  This is necessary to correctly process non-typed
              	multiline input (such as macros).
              	* IPython/Magic.py (Magic.format_latex): patch by Stefan van der
              	Walt <stefan-AT-sun.ac.za> to fix latex formatting of docstrings,
              	which was producing problems in the resulting manual.
              	(magic_whos): improve reporting of instances (show their class,
              	instead of simply printing 'instance' which isn't terribly
              	informative).
              	* IPython/genutils.py (shell): commit Jorgen Stenarson's patch
              	(minor mods) to support network shares under win32.
              	* IPython/winconsole.py (get_console_size): add new winconsole
              	module and fixes to page_dumb() to improve its behavior under
              	win32.  Contributed by Alexander Belchenko <bialix-AT-ukr.net>.
              	* IPython/Magic.py (Macro): simplified Macro class to just
              	subclass list.  We've had only 2.2 compatibility for a very long
              	time, yet I was still avoiding subclassing the builtin types.  No
              	more (I'm also starting to use properties, though I won't shift to
 .3-specific features quite yet).
              	(magic_store): added Ville's patch for lightweight variable
              	persistence, after a request on the user list by Matt Wilkie
              	<maphew-AT-gmail.com>.  The new %store magic's docstring has full
              	details.
              	* IPython/iplib.py (InteractiveShell.post_config_initialization):
              	changed the default logfile name from 'ipython.log' to
              	'ipython_log.py'.  These logs are real python files, and now that
              	we have much better multiline support, people are more likely to
              	want to use them as such.  Might as well name them correctly.
              	* IPython/Magic.py: substantial cleanup.  While we can't stop
              	using magics as mixins, due to the existing customizations 'out
              	there' which rely on the mixin naming conventions, at least I
              	cleaned out all cross-class name usage.  So once we are OK with
              	breaking compatibility, the two systems can be separated.
              	* IPython/Logger.py: major cleanup.  This one is NOT a mixin
              	anymore, and the class is a fair bit less hideous as well.  New
              	features were also introduced: timestamping of input, and logging
              	of output results.  These are user-visible with the -t and -o
              	options to %logstart.  Closes
              	http://www.scipy.net/roundup/ipython/issue11 and a request by
              	William Stein (SAGE developer - http://modular.ucsd.edu/sage).
 -12-28  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (handle_shell_escape): add Ville's patch to
              	better handle backslashes in paths.  See the thread 'More Windows
              	questions part 2 - \/ characters revisited' on the iypthon user
              	list:
              	http://scipy.net/pipermail/ipython-user/2005-June/000907.html
              	(InteractiveShell.__init__): fix tab-completion bug in threaded shells.
              	(InteractiveShell.__init__): change threaded shells to not use the
              	ipython crash handler.  This was causing more problems than not,
              	as exceptions in the main thread (GUI code, typically) would
              	always show up as a 'crash', when they really weren't.
              	The colors and exception mode commands (%colors/%xmode) have been
              	synchronized to also take this into account, so users can get
              	verbose exceptions for their threaded code as well.  I also added
              	support for activating pdb inside this exception handler as well,
              	so now GUI authors can use IPython's enhanced pdb at runtime.
              	* IPython/ipmaker.py (make_IPython): make the autoedit_syntax flag
              	true by default, and add it to the shipped ipythonrc file.  Since
              	this asks the user before proceeding, I think it's OK to make it
              	true by default.
              	* IPython/Magic.py (magic_exit): make new exit/quit magics instead
              	of the previous special-casing of input in the eval loop.  I think
              	this is cleaner, as they really are commands and shouldn't have
              	a special role in the middle of the core code.
 -12-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (edit_syntax_error): added support for
              	automatically reopening the editor if the file had a syntax error
              	in it.  Thanks to scottt who provided the patch at:
              	http://www.scipy.net/roundup/ipython/issue36 (slightly modified
              	version committed).
              	* IPython/iplib.py (handle_normal): add suport for multi-line
              	input with emtpy lines.  This fixes
              	http://www.scipy.net/roundup/ipython/issue43 and a similar
              	discussion on the user list.
              	WARNING: a behavior change is necessarily introduced to support
              	blank lines: now a single blank line with whitespace does NOT
              	break the input loop, which means that when autoindent is on, by
              	default hitting return on the next (indented) line does NOT exit.
              	Instead, to exit a multiline input you can either have:
              	  - TWO whitespace lines (just hit return again), or
              	  - a single whitespace line of a different length than provided
              	by the autoindent (add or remove a space).
              	* IPython/completer.py (MagicCompleter.__init__): new 'completer'
              	module to better organize all readline-related functionality.
              	I've deleted FlexCompleter and put all completion clases here.
              	* IPython/iplib.py (raw_input): improve indentation management.
              	It is now possible to paste indented code with autoindent on, and
              	the code is interpreted correctly (though it still looks bad on
              	screen, due to the line-oriented nature of ipython).
              	(MagicCompleter.complete): change behavior so that a TAB key on an
              	otherwise empty line actually inserts a tab, instead of completing
              	on the entire global namespace.  This makes it easier to use the
              	TAB key for indentation.  After a request by Hans Meine
              	<hans_meine-AT-gmx.net>
              	(_prefilter): add support so that typing plain 'exit' or 'quit'
              	does a sensible thing.  Originally I tried to deviate as little as
              	possible from the default python behavior, but even that one may
              	change in this direction (thread on python-dev to that effect).
              	Regardless, ipython should do the right thing even if CPython's
              	'>>>' prompt doesn't.
              	(InteractiveShell): removed subclassing code.InteractiveConsole
              	class.  By now we'd overridden just about all of its methods: I've
              	copied the remaining two over, and now ipython is a standalone
              	class.  This will provide a clearer picture for the chainsaw
              	branch refactoring.
 -12-26  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.text): harden reporting against
              	failures for objects which break when dir() is called on them.
              	* IPython/FlexCompleter.py (Completer.__init__): Added support for
              	distinct local and global namespaces in the completer API.  This
              	change allows us to properly handle completion with distinct
              	scopes, including in embedded instances (this had never really
              	worked correctly).
              	Note: this introduces a change in the constructor for
              	MagicCompleter, as a new global_namespace parameter is now the
              	second argument (the others were bumped one position).
 -12-25  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (embed_mainloop): fix tab-completion in
              	embedded instances (which can be done now thanks to Vivian's
              	frame-handling fixes for pdb).
              	(InteractiveShell.__init__): Fix namespace handling problem in
              	embedded instances.  We were overwriting __main__ unconditionally,
              	and this should only be done for 'full' (non-embedded) IPython;
              	embedded instances must respect the caller's __main__.  Thanks to
              	a bug report by Yaroslav Bulatov <yaroslavvb-AT-gmail.com>
 -12-24  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* setup.py: added download_url to setup().  This registers the
              	download address at PyPI, which is not only useful to humans
              	browsing the site, but is also picked up by setuptools (the Eggs
              	machinery).  Thanks to Ville and R. Kern for the info/discussion
              	on this.
 -12-23  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Debugger.py (Pdb.__init__): Major pdb mode enhancements.
              	This brings a lot of nice functionality to the pdb mode, which now
              	has tab-completion, syntax highlighting, and better stack handling
              	than before.  Many thanks to Vivian De Smedt
              	<vivian-AT-vdesmedt.com> for the original patches.
 -12-08  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): fix mainloop() calling
              	sequence to consistently accept the banner argument.  The
              	inconsistency was tripping SAGE, thanks to Gary Zablackis
              	<gzabl-AT-yahoo.com> for the report.
 -11-15  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.post_config_initialization):
              	Fix bug where a naked 'alias' call in the ipythonrc file would
              	cause a crash.  Bug reported by Jorgen Stenarson.
 -11-15  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): cleanups which should improve
              	startup time.
              	* IPython/iplib.py (runcode): my globals 'fix' for embedded
              	instances had introduced a bug with globals in normal code.  Now
              	it's working in all cases.
              	* IPython/Magic.py (magic_psearch): Finish wildcard cleanup and
              	API changes.  A new ipytonrc option, 'wildcards_case_sensitive'
              	has been introduced to set the default case sensitivity of the
              	searches.  Users can still select either mode at runtime on a
              	per-search basis.
 -11-13 Fernando Perez   <Fernando.Perez@colorado.edu>
              	* IPython/wildcard.py (NameSpace.__init__): fix resolution of
              	attributes in wildcard searches for subclasses.  Modified version
              	of a patch by Jorgen.
 -11-12 Fernando Perez   <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (embed_mainloop): Fix handling of globals for
              	embedded instances.  I added a user_global_ns attribute to the
              	InteractiveShell class to handle this.
 -10-31  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): Change timeout_add to
              	idle_add, which fixes horrible keyboard lag problems under gtk 2.6
              	(reported under win32, but may happen also in other platforms).
              	Bug report and fix courtesy of Sean Moore <smm-AT-logic.bm>
 -10-15  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Magic.py (magic_psearch): new support for wildcard
              	patterns.  Now, typing ?a*b will list all names which begin with a
              	and end in b, for example.  The %psearch magic has full
              	docstrings.  Many thanks to Jörgen Stenarson
              	<jorgen.stenarson-AT-bostream.nu>, author of the patches
              	implementing this functionality.
 -09-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* Manual: fixed long-standing annoyance of double-dashes (as in
              	--prefix=~, for example) being stripped in the HTML version.  This
              	is a latex2html bug, but a workaround was provided.  Many thanks
              	to George K. Thiruvathukal <gthiruv-AT-luc.edu> for the detailed
              	help, and Michael Tobis <mtobis-AT-gmail.com> for getting the ball
              	rolling.  This seemingly small issue had tripped a number of users
              	when first installing, so I'm glad to see it gone.
 -09-27  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Extensions/numeric_formats.py: fix missing import,
              	reported by Stephen Walton.
 -09-24  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py: finish demo module, fully documented now.
              	* IPython/genutils.py (file_read): simple little utility to read a
              	file and ensure it's closed afterwards.
 -09-23  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py (Demo.__init__): added support for individually
              	tagging blocks for automatic execution.
              	* IPython/Magic.py (magic_pycat): new %pycat magic for showing
              	syntax-highlighted python sources, requested by John.
 -09-22  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/demo.py (Demo.again): fix bug where again() blocks after
              	finishing.
              	* IPython/genutils.py (shlex_split): moved from Magic to here,
              	where all 2.2 compatibility stuff lives.  I needed it for demo.py.
              	* IPython/demo.py (Demo.__init__): added support for silent
              	blocks, improved marks as regexps, docstrings written.
              	(Demo.__init__): better docstring, added support for sys.argv.
              	* IPython/genutils.py (marquee): little utility used by the demo
              	code, handy in general.
              	* IPython/demo.py (Demo.__init__): new class for interactive
              	demos.  Not documented yet, I just wrote it in a hurry for
              	scipy'05.  Will docstring later.
 -09-20  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (sigint_handler): Drastic simplification which
              	also seems to make Ctrl-C work correctly across threads!  This is
              	so simple, that I can't beleive I'd missed it before.  Needs more
              	testing, though.
              	(KBINT): Never mind, revert changes.  I'm sure I'd tried something
              	like this before...
              	* IPython/genutils.py (get_home_dir): add protection against
              	non-dirs in win32 registry.
              	* IPython/iplib.py (InteractiveShell.alias_table_validate): fix
              	bug where dict was mutated while iterating (pysh crash).
 -09-06  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (handle_auto): Fix inconsistency arising from
              	spurious newlines added by this routine.  After a report by
              	F. Mantegazza.
 -09-05  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/Shell.py (hijack_gtk): remove pygtk.require("2.0")
              	calls.  These were a leftover from the GTK 1.x days, and can cause
              	problems in certain cases (after a report by John Hunter).
              	* IPython/iplib.py (InteractiveShell.__init__): Trap exception if
              	os.getcwd() fails at init time.  Thanks to patch from David Remahl
              	<chmod007-AT-mac.com>.
              	(InteractiveShell.__init__): prevent certain special magics from
              	being shadowed by aliases.  Closes
              	http://www.scipy.net/roundup/ipython/issue41.
 -08-31  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.complete): Added new
              	top-level completion method to expose the completion mechanism
              	beyond readline-based environments.
 -08-19  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* tools/ipsvnc (svnversion): fix svnversion capture.
              	* IPython/iplib.py (InteractiveShell.__init__): Add has_readline
              	attribute to self, which was missing.  Before, it was set by a
              	routine which in certain cases wasn't being called, so the
              	instance could end up missing the attribute.  This caused a crash.
              	Closes http://www.scipy.net/roundup/ipython/issue40.
 -08-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.text): don't crash if object
              	contains non-string attribute.  Closes
              	http://www.scipy.net/roundup/ipython/issue38.
 -08-14  Fernando Perez  <fperez@colorado.edu>
              	* tools/ipsvnc: Minor improvements, to add changeset info.
 -08-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (runsource): remove self.code_to_run_src
              	attribute.  I realized this is nothing more than
              	'\n'.join(self.buffer), and having the same data in two different
              	places is just asking for synchronization bugs.  This may impact
              	people who have custom exception handlers, so I need to warn
              	ipython-dev about it (F. Mantegazza may use them).
 -07-29  Fernando Perez  <Fernando.Perez@colorado.edu>
              	* IPython/genutils.py: fix 2.2 compatibility (generators)
 -07-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (get_home_dir): fix to help users with
              	invalid $HOME under win32.
 -07-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (str_safe): Make unicode-safe.  Also remove
              	some old hacks and clean up a bit other routines; code should be
              	simpler and a bit faster.
              	* IPython/iplib.py (interact): removed some last-resort attempts
              	to survive broken stdout/stderr.  That code was only making it
              	harder to abstract out the i/o (necessary for gui integration),
              	and the crashes it could prevent were extremely rare in practice
              	(besides being fully user-induced in a pretty violent manner).
              	* IPython/genutils.py (IOStream.__init__): Simplify the i/o stuff.
              	Nothing major yet, but the code is simpler to read; this should
              	make it easier to do more serious modifications in the future.
              	* IPython/Extensions/InterpreterExec.py: Fix auto-quoting in pysh,
              	which broke in .15 (thanks to a report by Ville).
              	* IPython/Itpl.py (Itpl.__init__): add unicode support (it may not
              	be quite correct, I know next to nothing about unicode).  This
              	will allow unicode strings to be used in prompts, amongst other
              	cases.  It also will prevent ipython from crashing when unicode
              	shows up unexpectedly in many places.  If ascii encoding fails, we
              	assume utf_8.  Currently the encoding is not a user-visible
              	setting, though it could be made so if there is demand for it.
              	* IPython/ipmaker.py (make_IPython): remove old 2.1-specific hack.
              	* IPython/Struct.py (Struct.merge): switch keys() to iterator.
              	* IPython/background_jobs.py: moved 2.2 compatibility to genutils.
              	* IPython/genutils.py: Add 2.2 compatibility here, so all other
              	code can work transparently for 2.2/2.3.
 -07-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (ExceptionColors): Make a global variable
              	out of the color scheme table used for coloring exception
              	tracebacks.  This allows user code to add new schemes at runtime.
              	This is a minimally modified version of the patch at
              	http://www.scipy.net/roundup/ipython/issue35, many thanks to pabw
              	for the contribution.
              	* IPython/FlexCompleter.py (Completer.attr_matches): Add a
              	slightly modified version of the patch in
              	http://www.scipy.net/roundup/ipython/issue34, which also allows me
              	to remove the previous try/except solution (which was costlier).
              	Thanks to Gaetan Lehmann <gaetan.lehmann-AT-jouy.inra.fr> for the fix.
 -06-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (write/write_err): Add methods to abstract all
              	I/O a bit more.
              	* IPython/Shell.py (IPShellGTK.mainloop): Fix GTK deprecation
              	warning, reported by Aric Hagberg, fix by JD Hunter.
 -06-02  *** Released version 0.6.15
 -06-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (MagicCompleter.file_matches): Fix
              	tab-completion of filenames within open-quoted strings.  Note that
              	this requires that in ~/.ipython/ipythonrc, users change the
              	readline delimiters configuration to read:
              	readline_remove_delims -/~
 -05-31  *** Released version 0.6.14
 -05-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.text): Fix crash for tracebacks
              	with files not on the filesystem.  Reported by Eliyahu Sandler
              	<eli@gondolin.net>
 -05-22  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py: Fix a few crashes in the --upgrade option.
              	After an initial report by LUK ShunTim <shuntim.luk@polyu.edu.hk>.
 -05-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (safe_execfile): close a file which could be
              	left open (causing problems in win32, which locks open files).
              	Thanks to a bug report by D Brown <dbrown2@yahoo.com>.
 -05-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): pass all
              	keyword arguments correctly to safe_execfile().
 -05-13  Fernando Perez  <fperez@colorado.edu>
              	* ipython.1: Added info about Qt to manpage, and threads warning
              	to usage page (invoked with --help).
              	* IPython/iplib.py (MagicCompleter.python_func_kw_matches): Added
              	new matcher (it goes at the end of the priority list) to do
              	tab-completion on named function arguments.  Submitted by George
              	Sakkis <gsakkis-AT-eden.rutgers.edu>.  See the thread at
              	http://www.scipy.net/pipermail/ipython-dev/2005-April/000436.html
              	for more details.
              	* IPython/Magic.py (magic_run): Added new -e flag to ignore
              	SystemExit exceptions in the script being run.  Thanks to a report
              	by danny shevitz <danny_shevitz-AT-yahoo.com>, about this
              	producing very annoying behavior when running unit tests.
 -05-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (handle_auto): fixed auto-quoting and parens,
              	which I'd broken (again) due to a changed regexp.  In the process,
              	added ';' as an escape to auto-quote the whole line without
              	splitting its arguments.  Thanks to a report by Jerry McRae
              	<qrs0xyc02-AT-sneakemail.com>.
              	* IPython/ultraTB.py (VerboseTB.text): protect against rare but
              	possible crashes caused by a TokenError.  Reported by Ed Schofield
              	<schofield-AT-ftw.at>.
 -05-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (hijack_wx): Fix to work with WX v.2.6.
 -04-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellQt): Thanks to Denis Rivière
              	<nudz-AT-free.fr>, Yann Cointepas <yann-AT-sapetnioc.org> and Benjamin
              	Thyreau <Benji2-AT-decideur.info>, we now have a -qthread option
              	which provides support for Qt interactive usage (similar to the
              	existing one for WX and GTK).  This had been often requested.
 -04-14  *** Released version 0.6.13
 -04-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic._ofind): remove docstring evaluation
              	from _ofind, which gets called on almost every input line.  Now,
              	we only try to get docstrings if they are actually going to be
              	used (the overhead of fetching unnecessary docstrings can be
              	noticeable for certain objects, such as Pyro proxies).
              	* IPython/iplib.py (MagicCompleter.python_matches): Change the API
              	for completers.  For some reason I had been passing them the state
              	variable, which completers never actually need, and was in
              	conflict with the rlcompleter API.  Custom completers ONLY need to
              	take the text parameter.
              	* IPython/Extensions/InterpreterExec.py: Fix regexp so that magics
              	work correctly in pysh.  I've also moved all the logic which used
              	to be in pysh.py here, which will prevent problems with future
              	upgrades.  However, this time I must warn users to update their
              	pysh profile to include the line
              	import_all IPython.Extensions.InterpreterExec
              	because otherwise things won't work for them.  They MUST also
              	delete pysh.py and the line
              	execfile pysh.py
              	from their ipythonrc-pysh.
              	* IPython/FlexCompleter.py (Completer.attr_matches): Make more
              	robust in the face of objects whose dir() returns non-strings
              	(which it shouldn't, but some broken libs like ITK do).  Thanks to
              	a patch by John Hunter (implemented differently, though).  Also
              	minor improvements by using .extend instead of + on lists.
              	* pysh.py:
 -04-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): Make multi_line_specials on
              	by default, so that all users benefit from it.  Those who don't
              	want it can still turn it off.
              	* IPython/UserConfig/ipythonrc: Add multi_line_specials to the
              	config file, I'd forgotten about this, so users were getting it
              	off by default.
              	* IPython/iplib.py (ipmagic): big overhaul of the magic system for
              	consistency.  Now magics can be called in multiline statements,
              	and python variables can be expanded in magic calls via $var.
              	This makes the magic system behave just like aliases or !system
              	calls.
 -03-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (handle_auto): cleanup to use %s instead of
              	expensive string additions for building command.  Add support for
              	trailing ';' when autocall is used.
 -03-26  Fernando Perez  <fperez@colorado.edu>
              	* ipython.el: Fix http://www.scipy.net/roundup/ipython/issue31.
              	Bugfix by A. Schmolck, the ipython.el maintainer.  Also make
              	ipython.el robust against prompts with any number of spaces
              	(including 0) after the ':' character.
              	* IPython/Prompts.py (Prompt2.set_p_str): Fix spurious space in
              	continuation prompt, which misled users to think the line was
              	already indented.  Closes debian Bug#300847, reported to me by
              	Norbert Tretkowski <tretkowski-AT-inittab.de>.
 -03-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (Prompt1.__str__): Make sure that prompts are
              	properly aligned if they have embedded newlines.
              	* IPython/iplib.py (runlines): Add a public method to expose
              	IPython's code execution machinery, so that users can run strings
              	as if they had been typed at the prompt interactively.
              	(InteractiveShell.__init__): Added getoutput() to the __IPYTHON__
              	methods which can call the system shell, but with python variable
              	expansion.  The three such methods are: __IPYTHON__.system,
              	.getoutput and .getoutputerror.  These need to be documented in a
              	'public API' section (to be written) of the manual.
 -03-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.set_custom_exc): new system
              	for custom exception handling.  This is quite powerful, and it
              	allows for user-installable exception handlers which can trap
              	custom exceptions at runtime and treat them separately from
              	IPython's default mechanisms.  At the request of Frédéric
              	Mantegazza <mantegazza-AT-ill.fr>.
              	(InteractiveShell.set_custom_completer): public API function to
              	add new completers at runtime.
 -03-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/OInspect.py (getdoc): Add a call to obj.getdoc(), to
              	allow objects which provide their docstrings via non-standard
              	mechanisms (like Pyro proxies) to still be inspected by ipython's
              	? system.
              	* IPython/iplib.py (InteractiveShell.__init__): back off the _o/_e
              	automatic capture system.  I tried quite hard to make it work
              	reliably, and simply failed.  I tried many combinations with the
              	subprocess module, but eventually nothing worked in all needed
              	cases (not blocking stdin for the child, duplicating stdout
              	without blocking, etc).  The new %sc/%sx still do capture to these
              	magical list/string objects which make shell use much more
              	conveninent, so not all is lost.
              	XXX - FIX MANUAL for the change above!
              	(runsource): I copied code.py's runsource() into ipython to modify
              	it a bit.  Now the code object and source to be executed are
              	stored in ipython.  This makes this info accessible to third-party
              	tools, like custom exception handlers.  After a request by Frédéric
              	Mantegazza <mantegazza-AT-ill.fr>.
              	* IPython/UserConfig/ipythonrc: Add up/down arrow keys to
              	history-search via readline (like C-p/C-n).  I'd wanted this for a
              	long time, but only recently found out how to do it.  For users
              	who already have their ipythonrc files made and want this, just
              	add:
              	readline_parse_and_bind "\e[A": history-search-backward
              	readline_parse_and_bind "\e[B": history-search-forward
 -03-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_sc): %sc and %sx now use the fancy
              	LSString and SList classes which allow transparent conversions
              	between list mode and whitespace-separated string.
              	(magic_r): Fix recursion problem in %r.
              	* IPython/genutils.py (LSString): New class to be used for
              	automatic storage of the results of all alias/system calls in _o
              	and _e (stdout/err).  These provide a .l/.list attribute which
              	does automatic splitting on newlines.  This means that for most
              	uses, you'll never need to do capturing of output with %sc/%sx
              	anymore, since ipython keeps this always done for you.  Note that
              	only the LAST results are stored, the _o/e variables are
              	overwritten on each call.  If you need to save their contents
              	further, simply bind them to any other name.
 -03-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (BasePrompt.cwd_filt): a few more fixes for
              	prompt namespace handling.
 -03-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (CachedOutput.__init__): Fix default and
              	classic prompts to be '>>> ' (final space was missing, and it
              	trips the emacs python mode).
              	(BasePrompt.__str__): Added safe support for dynamic prompt
              	strings.  Now you can set your prompt string to be '$x', and the
              	value of x will be printed from your interactive namespace.  The
              	interpolation syntax includes the full Itpl support, so
              	${foo()+x+bar()} is a valid prompt string now, and the function
              	calls will be made at runtime.
 -03-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_history): renamed %hist to %history, to
              	avoid name clashes in pylab.  %hist still works, it just forwards
              	the call to %history.
 -03-02  *** Released version 0.6.12
 -03-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (handle_magic): log magic calls properly as
              	ipmagic() function calls.
              	* IPython/Magic.py (magic_time): Improved %time to support
              	statements and provide wall-clock as well as CPU time.
 -02-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/hooks.py: New hooks module, to expose user-modifiable
              	IPython functionality in a clean manner.  For now only the editor
              	hook is actually written, and other thigns which I intend to turn
              	into proper hooks aren't yet there.  The display and prefilter
              	stuff, for example, should be hooks.  But at least now the
              	framework is in place, and the rest can be moved here with more
              	time later.  IPython had had a .hooks variable for a long time for
              	this purpose, but I'd never actually used it for anything.
 -02-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): make the default ipython
              	directory be called _ipython under win32, to follow more the
              	naming peculiarities of that platform (where buggy software like
              	Visual Sourcesafe breaks with .named directories).  Reported by
              	Ville Vainio.
 -02-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): removed a few
              	auto_aliases for win32 which were causing problems.  Users can
              	define the ones they personally like.
 -02-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_time): new magic to time execution of
              	expressions.  After a request by Charles Moad <cmoad-AT-indiana.edu>.
 -02-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ConfigLoader.py (ConfigLoader.load): Allow empty strings
              	into keys (for prompts, for example).
              	* IPython/Prompts.py (BasePrompt.set_p_str): Fix to allow empty
              	prompts in case users want them.  This introduces a small behavior
              	change: ipython does not automatically add a space to all prompts
              	anymore.  To get the old prompts with a space, users should add it
              	manually to their ipythonrc file, so for example prompt_in1 should
              	now read 'In [\#]: ' instead of 'In [\#]:'.
              	(BasePrompt.__init__): New option prompts_pad_left (only in rc
              	file) to control left-padding of secondary prompts.
              	* IPython/Magic.py (Magic.profile_missing_notice): Don't crash if
              	the profiler can't be imported.  Fix for Debian, which removed
              	profile.py because of License issues.  I applied a slightly
              	modified version of the original Debian patch at
              	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=294500.
 -02-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (native_line_ends): Fix bug which would
              	cause improper line-ends under win32 b/c I was not opening files
              	in binary mode.  Bug report and fix thanks to Ville.
              	* IPython/iplib.py (handle_auto): Fix bug which I introduced when
              	trying to catch spurious foo[1] autocalls.  My fix actually broke
              	',/' autoquote/call with explicit escape (bad regexp).
 -02-15  *** Released version 0.6.11
 -02-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/background_jobs.py: New background job management
              	subsystem.  This is implemented via a new set of classes, and
              	IPython now provides a builtin 'jobs' object for background job
              	execution.  A convenience %bg magic serves as a lightweight
              	frontend for starting the more common type of calls.  This was
              	inspired by discussions with B. Granger and the BackgroundCommand
              	class described in the book Python Scripting for Computational
              	Science, by H. P. Langtangen: http://folk.uio.no/hpl/scripting
              	(although ultimately no code from this text was used, as IPython's
              	system is a separate implementation).
              	* IPython/iplib.py (MagicCompleter.python_matches): add new option
              	to control the completion of single/double underscore names
              	separately.  As documented in the example ipytonrc file, the
              	readline_omit__names variable can now be set to 2, to omit even
              	single underscore names.  Thanks to a patch by Brian Wong
              	<BrianWong-AT-AirgoNetworks.Com>.
              	(InteractiveShell.__init__): Fix bug which would cause foo[1] to
              	be autocalled as foo([1]) if foo were callable.  A problem for
              	things which are both callable and implement __getitem__.
              	(init_readline): Fix autoindentation for win32.  Thanks to a patch
              	by Vivian De Smedt <vivian-AT-vdesmedt.com>.
 -02-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): Disabled the stout traps
              	which I had written long ago to sort out user error messages which
              	may occur during startup.  This seemed like a good idea initially,
              	but it has proven a disaster in retrospect.  I don't want to
              	change much code for now, so my fix is to set the internal 'debug'
              	flag to true everywhere, whose only job was precisely to control
              	this subsystem.  This closes issue 28 (as well as avoiding all
              	sorts of strange hangups which occur from time to time).
 -02-07  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_edit): Fix 'ed -p' not working when the
              	previous call produced a syntax error.
              	* IPython/OInspect.py (Inspector.pinfo): Fix crash when inspecting
              	classes without constructor.
 -02-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (MagicCompleter.complete): Extend the list of
              	completions with the results of each matcher, so we return results
              	to the user from all namespaces.  This breaks with ipython
              	tradition, but I think it's a nicer behavior.  Now you get all
              	possible completions listed, from all possible namespaces (python,
              	filesystem, magics...)  After a request by John Hunter
              	<jdhunter-AT-nitace.bsd.uchicago.edu>.
 -02-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_prun): Fix bug where prun would fail if
              	the call had quote characters in it (the quotes were stripped).
 -01-31  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): reduce reliance on
              	Itpl.itpl() to make the code more robust against psyco
              	optimizations.
              	* IPython/Itpl.py (Itpl.__str__): Use a _getframe() call instead
              	of causing an exception.  Quicker, cleaner.
 -01-28  Fernando Perez  <fperez@colorado.edu>
              	* scripts/ipython_win_post_install.py (install): hardcode
              	sys.prefix+'python.exe' as the executable path.  It turns out that
              	during the post-installation run, sys.executable resolves to the
              	name of the binary installer!  I should report this as a distutils
              	bug, I think.  I updated the .10 release with this tiny fix, to
              	avoid annoying the lists further.
 -01-27  *** Released version 0.6.10
 -01-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (norm): Added 'inf' as optional name for
              	L-infinity norm, included references to mathworld.com for vector
              	norm definitions.
              	(amin/amax): added amin/amax for array min/max.  Similar to what
              	pylab ships with after the recent reorganization of names.
              	(spike/spike_odd): removed deprecated spike/spike_odd functions.
              	* ipython.el: committed Alex's recent fixes and improvements.
              	Tested with python-mode from CVS, and it looks excellent.  Since
              	python-mode hasn't released anything in a while, I'm temporarily
              	putting a copy of today's CVS (v 4.70) of python-mode in:
              	  http://ipython.scipy.org/tmp/python-mode.el
              	* scripts/ipython_win_post_install.py (install): Win32 fix to use
              	sys.executable for the executable name, instead of assuming it's
              	called 'python.exe' (the post-installer would have produced broken
              	setups on systems with a differently named python binary).
              	* IPython/PyColorize.py (Parser.__call__): change explicit '\n'
              	references to os.linesep, to make the code more
              	platform-independent.  This is also part of the win32 coloring
              	fixes.
              	* IPython/genutils.py (page_dumb): Remove attempts to chop long
              	lines, which actually cause coloring bugs because the length of
              	the line is very difficult to correctly compute with embedded
              	escapes.  This was the source of all the coloring problems under
              	Win32.  I think that _finally_, Win32 users have a properly
              	working ipython in all respects.  This would never have happened
              	if not for Gary Bishop and Viktor Ransmayr's great help and work.
 -01-26  *** Released version 0.6.9
 -01-25  Fernando Perez  <fperez@colorado.edu>
              	* setup.py: finally, we have a true Windows installer, thanks to
              	the excellent work of Viktor Ransmayr
              	<viktor.ransmayr-AT-t-online.de>.  The docs have been updated for
              	Windows users.  The setup routine is quite a bit cleaner thanks to
              	this, and the post-install script uses the proper functions to
              	allow a clean de-installation using the standard Windows Control
              	Panel.
              	* IPython/genutils.py (get_home_dir): changed to use the $HOME
              	environment variable under all OSes (including win32) if
              	available.  This will give consistency to win32 users who have set
              	this variable for any reason.  If os.environ['HOME'] fails, the
              	previous policy of using HOMEDRIVE\HOMEPATH kicks in.
 -01-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (empty_like): add empty_like(), similar to
              	zeros_like() but taking advantage of the new empty() Numeric routine.
 -01-23  *** Released version 0.6.8
 -01-22  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): I removed the
              	automatic show() calls.  After discussing things with JDH, it
              	turns out there are too many corner cases where this can go wrong.
              	It's best not to try to be 'too smart', and simply have ipython
              	reproduce as much as possible the default behavior of a normal
              	python shell.
              	* IPython/iplib.py (InteractiveShell.__init__): Modified the
              	line-splitting regexp and _prefilter() to avoid calling getattr()
              	on assignments.  This closes
              	http://www.scipy.net/roundup/ipython/issue24.  Note that Python's
              	readline uses getattr(), so a simple <TAB> keypress is still
              	enough to trigger getattr() calls on an object.
 -01-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.magic_run): Fix the %run
              	docstring under pylab so it doesn't mask the original.
 -01-21  *** Released version 0.6.7
 -01-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MTInteractiveShell.runcode): Trap a crash with
              	signal handling for win32 users in multithreaded mode.
 -01-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/OInspect.py (Inspector.pinfo): Fix crash when inspecting
              	instances with no __init__.  After a crash report by Norbert Nemec
              	<Norbert-AT-nemec-online.de>.
 -01-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.text): Fix bug in reporting of
              	names for verbose exceptions, when multiple dotted names and the
              	'parent' object were present on the same line.
 -01-11  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (flag_calls): new utility to trap and flag
              	calls in functions.  I need it to clean up matplotlib support.
              	Also removed some deprecated code in genutils.
              	* IPython/Shell.py (MatplotlibShellBase.mplot_exec): small fix so
              	that matplotlib scripts called with %run, which don't call show()
              	themselves, still have their plotting windows open.
 -01-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.__init__): Patch by Andrew Straw
              	<astraw-AT-caltech.edu>, to fix gtk deprecation warnings.
 -12-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MTInteractiveShell.runcode): Get rid of
              	parent_runcode, which was an eyesore.  The same result can be
              	obtained with Python's regular superclass mechanisms.
 -12-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_sc): Fix quote stripping problem
              	reported by Prabhu.
              	(Magic.magic_sx): direct all errors to Term.cerr (defaults to
              	sys.stderr) instead of explicitly calling sys.stderr.  This helps
              	maintain our I/O abstractions clean, for future GUI embeddings.
              	* IPython/genutils.py (info): added new utility for sys.stderr
              	unified info message handling (thin wrapper around warn()).
              	* IPython/ultraTB.py (VerboseTB.text): Fix misreported global
              	composite (dotted) names on verbose exceptions.
              	(VerboseTB.nullrepr): harden against another kind of errors which
              	Python's inspect module can trigger, and which were crashing
              	IPython.  Thanks to a report by Marco Lombardi
              	<mlombard-AT-ma010192.hq.eso.org>.
 -12-13  *** Released version 0.6.6
 -12-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): catch RuntimeErrors
              	generated by pygtk upon initialization if it was built without
              	threads (for matplotlib users).  After a crash reported by
              	Leguijt, Jaap J SIEP-EPT-RES <Jaap.Leguijt-AT-shell.com>.
              	* IPython/ipmaker.py (make_IPython): fix small bug in the
              	import_some parameter for multiple imports.
              	* IPython/iplib.py (ipmagic): simplified the interface of
              	ipmagic() to take a single string argument, just as it would be
              	typed at the IPython cmd line.
              	(ipalias): Added new ipalias() with an interface identical to
              	ipmagic().  This completes exposing a pure python interface to the
              	alias and magic system, which can be used in loops or more complex
              	code where IPython's automatic line mangling is not active.
              	* IPython/genutils.py (timing): changed interface of timing to
              	simply run code once, which is the most common case.  timings()
              	remains unchanged, for the cases where you want multiple runs.
              	* IPython/Shell.py (MatplotlibShellBase._matplotlib_config): Fix a
              	bug where Python2.2 crashes with exec'ing code which does not end
              	in a single newline.  Python 2.3 is OK, so I hadn't noticed this
              	before.
 -12-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_prun): changed name of option from
              	-t to -T, to accomodate the new -t flag in %run (the %run and
              	%prun options are kind of intermixed, and it's not easy to change
              	this with the limitations of python's getopt).
              	* IPython/Magic.py (Magic.magic_run): Added new -t option to time
              	the execution of scripts.  It's not as fine-tuned as timeit.py,
              	but it works from inside ipython (and under 2.2, which lacks
              	timeit.py).  Optionally a number of runs > 1 can be given for
              	timing very short-running code.
              	* IPython/genutils.py (uniq_stable): new routine which returns a
              	list of unique elements in any iterable, but in stable order of
              	appearance.  I needed this for the ultraTB fixes, and it's a handy
              	utility.
              	* IPython/ultraTB.py (VerboseTB.text): Fix proper reporting of
              	dotted names in Verbose exceptions.  This had been broken since
              	the very start, now x.y will properly be printed in a Verbose
              	traceback, instead of x being shown and y appearing always as an
              	'undefined global'.  Getting this to work was a bit tricky,
              	because by default python tokenizers are stateless.  Saved by
              	python's ability to easily add a bit of state to an arbitrary
              	function (without needing to build a full-blown callable object).
              	Also big cleanup of this code, which had horrendous runtime
              	lookups of zillions of attributes for colorization.  Moved all
              	this code into a few templates, which make it cleaner and quicker.
              	Printout quality was also improved for Verbose exceptions: one
              	variable per line, and memory addresses are printed (this can be
              	quite handy in nasty debugging situations, which is what Verbose
              	is for).
              	* IPython/ipmaker.py (make_IPython): Do NOT execute files named in
              	the command line as scripts to be loaded by embedded instances.
              	Doing so has the potential for an infinite recursion if there are
              	exceptions thrown in the process.  This fixes a strange crash
              	reported by Philippe MULLER <muller-AT-irit.fr>.
 -12-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.use): Change pylab support
              	to reflect new names in matplotlib, which now expose the
              	matlab-compatible interface via a pylab module instead of the
              	'matlab' name.  The new code is backwards compatible, so users of
              	all matplotlib versions are OK.  Patch by J. Hunter.
              	* IPython/OInspect.py (Inspector.pinfo): Add to object? printing
              	of __init__ docstrings for instances (class docstrings are already
              	automatically printed).  Instances with customized docstrings
              	(indep. of the class) are also recognized and all 3 separate
              	docstrings are printed (instance, class, constructor).  After some
              	comments/suggestions by J. Hunter.
 -12-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (MagicCompleter.complete): Remove annoying
              	warnings when tab-completion fails and triggers an exception.
 -12-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (magic_prun): Fix bug where an exception would
              	be triggered when using 'run -p'.  An incorrect option flag was
              	being set ('d' instead of 'D').
              	(manpage): fix missing escaped \- sign.
 -11-30  *** Released version 0.6.5
 -11-30  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_run): Fix bug in breakpoint
              	setting with -d option.
              	* setup.py (docfiles): Fix problem where the doc glob I was using
              	was COMPLETELY BROKEN.  It was giving the right files by pure
              	accident, but failed once I tried to include ipython.el.  Note:
              	glob() does NOT allow you to do exclusion on multiple endings!
 -11-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/usage.py (__doc__): cleaned up usage docstring, by using
              	the manpage as the source.  Better formatting & consistency.
              	* IPython/Magic.py (magic_run): Added new -d option, to run
              	scripts under the control of the python pdb debugger.  Note that
              	this required changing the %prun option -d to -D, to avoid a clash
              	(since %run must pass options to %prun, and getopt is too dumb to
              	handle options with string values with embedded spaces).  Thanks
              	to a suggestion by Matthew Arnison <maffew-AT-cat.org.au>.
              	(magic_who_ls): added type matching to %who and %whos, so that one
              	can filter their output to only include variables of certain
              	types.  Another suggestion by Matthew.
              	(magic_whos): Added memory summaries in kb and Mb for arrays.
              	(magic_who): Improve formatting (break lines every 9 vars).
 -11-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.log): Fix bug in syncing the input
              	cache when empty lines were present.
 -11-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/usage.py (__doc__): document the re-activated threading
              	options for WX and GTK.
 -11-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (start): Added Prabhu's big patch to reactivate
              	the -wthread and -gthread options, along with a new -tk one to try
              	and coordinate Tk threading with wx/gtk.  The tk support is very
              	platform dependent, since it seems to require Tcl and Tk to be
              	built with threads (Fedora1/2 appears NOT to have it, but in
              	Prabhu's Debian boxes it works OK).  But even with some Tk
              	limitations, this is a great improvement.
              	* IPython/Prompts.py (prompt_specials_color): Added \t for time
              	info in user prompts.  Patch by Prabhu.
 -11-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (ask_yes_no): Add check for a max of 20
              	EOFErrors and bail, to avoid infinite loops if a non-terminating
              	file is fed into ipython.  Patch submitted in issue 19 by user,
              	many thanks.
              	* IPython/iplib.py (InteractiveShell.handle_auto): do NOT trigger
              	autoquote/parens in continuation prompts, which can cause lots of
              	problems.  Closes roundup issue 20.
 -11-17  Fernando Perez  <fperez@colorado.edu>
              	* debian/control (Build-Depends-Indep): Fix dpatch dependency,
              	reported as debian bug #280505.  I'm not sure my local changelog
              	entry has the proper debian format (Jack?).
 -11-08  *** Released version 0.6.4
 -11-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (init_readline): Fix exit message for Windows
              	when readline is active.  Thanks to a report by Eric Jones
              	<eric-AT-enthought.com>.
 -11-07  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page): Add a trap for OSError exceptions,
              	sometimes seen by win2k/cygwin users.
 -11-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (interact): Change the handling of %Exit from
              	trying to propagate a SystemExit to an internal ipython flag.
              	This is less elegant than using Python's exception mechanism, but
              	I can't get that to work reliably with threads, so under -pylab
              	%Exit was hanging IPython.  Cross-thread exception handling is
              	really a bitch.  Thaks to a bug report by Stephen Walton
              	<stephen.walton-AT-csun.edu>.
 -11-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (raw_input_original): store a pointer to the
              	true raw_input to harden against code which can modify it
              	(wx.py.PyShell does this and would otherwise crash ipython).
              	Thanks to a bug report by Jim Flowers <james.flowers-AT-lgx.com>.
              	* IPython/Shell.py (MTInteractiveShell.runsource): Cleaner fix for
              	Ctrl-C problem, which does not mess up the input line.
 -11-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Release.py: Changed licensing to BSD, in all files.
              	(name): lowercase name for tarball/RPM release.
              	* IPython/OInspect.py (getdoc): wrap inspect.getdoc() safely for
              	use throughout ipython.
              	* IPython/Magic.py (Magic._ofind): Switch to using the new
              	OInspect.getdoc() function.
              	* IPython/Shell.py (sigint_handler): Hack to ignore the execution
              	of the line currently being canceled via Ctrl-C.  It's extremely
              	ugly, but I don't know how to do it better (the problem is one of
              	handling cross-thread exceptions).
 -10-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (signal_handler): add signal handlers to trap
              	SIGINT and SIGSEGV in threaded code properly.  Thanks to a bug
              	report by Francesc Alted.
 -10-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Extensions/InterpreterExec.py (prefilter_shell): Fix @
              	to % for pysh syntax extensions.
 -10-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_whos): modify output of Numeric
              	arrays to print a more useful summary, without calling str(arr).
              	This avoids the problem of extremely lengthy computations which
              	occur if arr is large, and appear to the user as a system lockup
              	with 100% cpu activity.  After a suggestion by Kristian Sandberg
              	<Kristian.Sandberg@colorado.edu>.
              	(Magic.__init__): fix bug in global magic escapes not being
              	correctly set.
 -10-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (__license__): change to absolute imports of
              	ipython's own internal packages, to start adapting to the absolute
              	import requirement of PEP-328.
              	* IPython/genutils.py (__author__): Fix coding to utf-8 on all
              	files, and standardize author/license marks through the Release
              	module instead of having per/file stuff (except for files with
              	particular licenses, like the MIT/PSF-licensed codes).
              	* IPython/Debugger.py: remove dead code for python 2.1
 -10-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (ipmagic): New function for accessing magics
              	via a normal python function call.
              	* IPython/Magic.py (Magic.magic_magic): Change the magic escape
              	from '@' to '%', to accomodate the new @decorator syntax of python
 .4.
 -09-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.use): Added a wrapper to
              	matplotlib.use to prevent running scripts which try to switch
              	interactive backends from within ipython.  This will just crash
              	the python interpreter, so we can't allow it (but a detailed error
              	is given to the user).
 -09-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (MatplotlibShellBase.mplot_exec):
              	matplotlib-related fixes so that using @run with non-matplotlib
              	scripts doesn't pop up spurious plot windows.  This requires
              	matplotlib >= 0.63, where I had to make some changes as well.
              	* IPython/ipmaker.py (make_IPython): update version requirement to
              	python 2.2.
              	* IPython/iplib.py (InteractiveShell.mainloop): Add an optional
              	banner arg for embedded customization.
              	* IPython/Magic.py (Magic.__init__): big cleanup to remove all
              	explicit uses of __IP as the IPython's instance name.  Now things
              	are properly handled via the shell.name value.  The actual code
              	is a bit ugly b/c I'm doing it via a global in Magic.py, but this
              	is much better than before.  I'll clean things completely when the
              	magic stuff gets a real overhaul.
              	* ipython.1: small fixes, sent in by Jack Moffit.  He also sent in
              	minor changes to debian dir.
              	* IPython/iplib.py (InteractiveShell.__init__): Fix adding a
              	pointer to the shell itself in the interactive namespace even when
              	a user-supplied dict is provided.  This is needed for embedding
              	purposes (found by tests with Michel Sanner).
 -09-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/ipythonrc: remove []{} from
              	readline_remove_delims, so that things like [modname.<TAB> do
              	proper completion.  This disables [].TAB, but that's a less common
              	case than module names in list comprehensions, for example.
              	Thanks to a report by Andrea Riciputi.
 -09-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellGTK.mainloop): reorder to avoid
              	blocking problems in win32 and osx.  Fix by John.
 -09-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellWX.OnInit): Fix output redirection bug
              	for Win32 and OSX.  Fix by John Hunter.
 -08-30  *** Released version 0.6.3
 -08-30  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (isfile): Add manpages to list of dependent files to be
              	updated.
 -08-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (start): I've disabled -wthread and -gthread
              	for now.  They don't really work with standalone WX/GTK code
              	(though matplotlib IS working fine with both of those backends).
              	This will neeed much more testing.  I disabled most things with
              	comments, so turning it back on later should be pretty easy.
              	* IPython/iplib.py (InteractiveShell.__init__): Fix accidental
              	autocalling of expressions like r'foo', by modifying the line
              	split regexp.  Closes
              	http://www.scipy.net/roundup/ipython/issue18, reported by Nicholas
              	Riley <ipythonbugs-AT-sabi.net>.
              	(InteractiveShell.mainloop): honor --nobanner with banner
              	extensions.
              	* IPython/Shell.py: Significant refactoring of all classes, so
              	that we can really support ALL matplotlib backends and threading
              	models (John spotted a bug with Tk which required this).  Now we
              	should support single-threaded, WX-threads and GTK-threads, both
              	for generic code and for matplotlib.
              	* IPython/ipmaker.py (__call__): Changed -mpthread option to
              	-pylab, to simplify things for users.  Will also remove the pylab
              	profile, since now all of matplotlib configuration is directly
              	handled here.  This also reduces startup time.
              	* IPython/Shell.py (IPShellGTK.run): Fixed bug where mainloop() of
              	shell wasn't being correctly called.  Also in IPShellWX.
              	* IPython/iplib.py (InteractiveShell.__init__): Added option to
              	fine-tune banner.
              	* IPython/numutils.py (spike): Deprecate these spike functions,
              	delete (long deprecated) gnuplot_exec handler.
 -08-26  Fernando Perez  <fperez@colorado.edu>
              	* ipython.1: Update for threading options, plus some others which
              	were missing.
              	* IPython/ipmaker.py (__call__): Added -wthread option for
              	wxpython thread handling.  Make sure threading options are only
              	valid at the command line.
              	* scripts/ipython: moved shell selection into a factory function
              	in Shell.py, to keep the starter script to a minimum.
 -08-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellWX.wxexit): fixes to WX threading, by
              	John.  Along with some recent changes he made to matplotlib, the
              	next versions of both systems should work very well together.
 -08-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_prun): cleanup some dead code.  I
              	tried to switch the profiling to using hotshot, but I'm getting
              	strange errors from prof.runctx() there.  I may be misreading the
              	docs, but it looks weird.  For now the profiling code will
              	continue to use the standard profiler.
 -08-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellWX.__init__): Improvements to the WX
              	threaded shell, by John Hunter.  It's not quite ready yet, but
              	close.
 -08-22  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): tab cleanups, also
              	in Magic and ultraTB.
              	* ipython.1: document threading options in manpage.
              	* scripts/ipython: Changed name of -thread option to -gthread,
              	since this is GTK specific.  I want to leave the door open for a
              	-wthread option for WX, which will most likely be necessary.  This
              	change affects usage and ipmaker as well.
              	* IPython/Shell.py (matplotlib_shell): Add a factory function to
              	handle the matplotlib shell issues.  Code by John Hunter
              	<jdhunter-AT-nitace.bsd.uchicago.edu>.
              	(IPShellMatplotlibWX.__init__): Rudimentary WX support.  It's
              	broken (and disabled for end users) for now, but it puts the
              	infrastructure in place.
 -08-21  Fernando Perez  <fperez@colorado.edu>
              	* ipythonrc-pylab: Add matplotlib support.
              	* matplotlib_config.py: new files for matplotlib support, part of
              	the pylab profile.
              	* IPython/usage.py (__doc__): documented the threading options.
 -08-20  Fernando Perez  <fperez@colorado.edu>
              	* ipython: Modified the main calling routine to handle the -thread
              	and -mpthread options.  This needs to be done as a top-level hack,
              	because it determines which class to instantiate for IPython
              	itself.
              	* IPython/Shell.py (MTInteractiveShell.__init__): New set of
              	classes to support multithreaded GTK operation without blocking,
              	and matplotlib with all backends.  This is a lot of still very
              	experimental code, and threads are tricky.  So it may still have a
              	few rough edges...  This code owes a lot to
              	http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65109, by
              	Brian # McErlean and John Finlay, to Antoon Pardon for fixes, and
              	to John Hunter for all the matplotlib work.
              	* IPython/ipmaker.py (__call__): Added -thread and -mpthread
              	options for gtk thread and matplotlib support.
 -08-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): don't trigger
              	autocall for things like p*q,p/q,p+q,p-q, when p is callable.  Bug
              	reported by Stephen Walton <stephen.walton-AT-csun.edu>.
 -08-11  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (isfile): Fix build so documentation gets updated for
              	rpms (it was only done for .tgz builds).
 -08-10  Fernando Perez  <fperez@colorado.edu>
              	* genutils.py (Term): Fix misspell of stdin stream (sin->cin).
              	* iplib.py : Silence syntax error exceptions in tab-completion.
 -08-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (Prompt2.set_colors): Fix incorrectly set
              	'color off' mark for continuation prompts.  This was causing long
              	continuation lines to mis-wrap.
 -08-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): Allow the shell class used
              	for building ipython to be a parameter.  All this is necessary
              	right now to have a multithreaded version, but this insane
              	non-design will be cleaned up soon.  For now, it's a hack that
              	works.
              	* IPython/Shell.py (IPShell.__init__): Stop using mutable default
              	args in various places.  No bugs so far, but it's a dangerous
              	practice.
 -07-31  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (complete): ignore SyntaxError exceptions to
              	fix completion of files with dots in their names under most
              	profiles (pysh was OK because the completion order is different).
 -07-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): build dict of
              	keywords manually, b/c the one in keyword.py was removed in python
 .4.  Patch by Anakim Border <aborder-AT-users.sourceforge.net>.
              	This is NOT a bug under python 2.3 and earlier.
 -07-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.text): Add another
              	linecache.checkcache() call to try to prevent inspect.py from
              	crashing under python 2.3.  I think this fixes
              	http://www.scipy.net/roundup/ipython/issue17.
 -07-26  *** Released version 0.6.2
 -07-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_cd): Fix bug where 'cd -N' would
              	fail for any number.
              	(Magic.magic_bookmark): Fix bug where 'bookmark -l' would fail for
              	empty bookmarks.
 -07-26  *** Released version 0.6.1
 -07-26  Fernando Perez  <fperez@colorado.edu>
              	* ipython_win_post_install.py (run): Added pysh shortcut for Windows.
              	* IPython/iplib.py (protect_filename): Applied Ville's patch for
              	escaping '()[]{}' in filenames.
              	* IPython/Magic.py (shlex_split): Fix handling of '*' and '?' for
              	Python 2.2 users who lack a proper shlex.split.
 -07-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.init_readline): Add support
              	for reading readline's init file.  I follow the normal chain:
              	$INPUTRC is honored, otherwise ~/.inputrc is used.  Thanks to a
              	report by Mike Heeter.  This closes
              	http://www.scipy.net/roundup/ipython/issue16.
 -07-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (__init__): Add better handling of '\' under
              	Win32 for filenames.  After a patch by Ville.
 -07-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): fix bug where
              	autocalling would be triggered for 'foo is bar' if foo is
              	callable.  I also cleaned up the autocall detection code to use a
              	regexp, which is faster.  Bug reported by Alexander Schmolck.
              	* IPython/Magic.py (Magic.magic_pinfo): Fix bug where strings with
              	'?' in them would confuse the help system.  Reported by Alex
              	Schmolck.
 -07-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/GnuplotInteractive.py (__all__): added plot2.
              	* IPython/Gnuplot2.py (Gnuplot.plot2): added new function for
              	plotting dictionaries, lists or tuples of 1d arrays.
              	* IPython/Magic.py (Magic.magic_hist): small clenaups and
              	optimizations.
              	* IPython/iplib.py:Remove old Changelog info for cleanup.  This is
              	the information which was there from Janko's original IPP code:
 .05.99 20:53 porto.ifm.uni-kiel.de
              	--Started changelog.
              	--make clear do what it say it does
              	--added pretty output of lines from inputcache
              	--Made Logger a mixin class, simplifies handling of switches
              	--Added own completer class. .string<TAB> expands to last history
              	line which starts with string.  The new expansion is also present
              	with Ctrl-r from the readline library.  But this shows, who this
              	can be done for other cases.
              	--Added convention that all shell functions should accept a
              	parameter_string This opens the door for different behaviour for
              	each function. @cd is a good example of this.
 .05.99 12:12 porto.ifm.uni-kiel.de
              	--added logfile rotation
              	--added new mainloop method which freezes first the namespace
 .05.99 21:24 porto.ifm.uni-kiel.de
              	--added the docreader classes. Now there is a help system.
              	-This is only a first try. Currently it's not easy to put new
              	stuff in the indices. But this is the way to go. Info would be
              	better, but HTML is every where and not everybody has an info
              	system installed and it's not so easy to change html-docs to info.
              	--added global logfile option
              	--there is now a hook for object inspection method pinfo needs to
              	be provided for this. Can be reached by two '??'.
 .05.99 20:51 porto.ifm.uni-kiel.de
              	--added a README
              	--bug in rc file. Something has changed so functions in the rc
              	file need to reference the shell and not self. Not clear if it's a
              	bug or feature.
              	--changed rc file for new behavior
 -07-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.log): fixed recent bug where the input
              	cache was falling out of sync in bizarre manners when multi-line
              	input was present.  Minor optimizations and cleanup.
              	(Logger): Remove old Changelog info for cleanup.  This is the
              	information which was there from Janko's original code:
              	Changes to Logger: - made the default log filename a parameter
              	- put a check for lines beginning with !@? in log(). Needed
              	(even if the handlers properly log their lines) for mid-session
              	logging activation to work properly. Without this, lines logged
              	in mid session, which get read from the cache, would end up
              	'bare' (with !@? in the open) in the log. Now they are caught
              	and prepended with a #.
              	* IPython/iplib.py (InteractiveShell.init_readline): added check
              	in case MagicCompleter fails to be defined, so we don't crash.
 -07-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Gnuplot2.py (Gnuplot.hardcopy): add automatic generation
              	of EPS if the requested filename ends in '.eps'.
 -07-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.handle_shell_escape): Fix
              	escaping of quotes when calling the shell.
 -07-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (CachedOutput.update): Fix problem with
              	gettext not working because we were clobbering '_'.  Fixes
              	http://www.scipy.net/roundup/ipython/issue6.
 -07-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_cd): integrated bookmark handling
              	into @cd.  Patch by Ville.
              	* IPython/iplib.py (InteractiveShell.post_config_initialization):
              	new function to store things after ipmaker runs.  Patch by Ville.
              	Eventually this will go away once ipmaker is removed and the class
              	gets cleaned up, but for now it's ok.  Key functionality here is
              	the addition of the persistent storage mechanism, a dict for
              	keeping data across sessions (for now just bookmarks, but more can
              	be implemented later).
              	* IPython/Magic.py (Magic.magic_bookmark): New bookmark system,
              	persistent across sections.  Patch by Ville, I modified it
              	soemwhat to allow bookmarking arbitrary dirs other than CWD.  Also
              	added a '-l' option to list all bookmarks.
              	* IPython/iplib.py (InteractiveShell.atexit_operations): new
              	center for cleanup.  Registered with atexit.register().  I moved
              	here the old exit_cleanup().  After a patch by Ville.
              	* IPython/Magic.py (get_py_filename): added '~' to the accepted
              	characters in the hacked shlex_split for python 2.2.
              	* IPython/iplib.py (file_matches): more fixes to filenames with
              	whitespace in them.  It's not perfect, but limitations in python's
              	readline make it impossible to go further.
 -06-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (file_matches): escape whitespace correctly in
              	filename completions.  Bug reported by Ville.
 -06-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (__call__): Added per-profile histories.  Now
              	the history file will be called 'history-PROFNAME' (or just
              	'history' if no profile is loaded).  I was getting annoyed at
              	getting my Numerical work history clobbered by pysh sessions.
              	* IPython/iplib.py (InteractiveShell.__init__): Internal
              	getoutputerror() function so that we can honor the system_verbose
              	flag for _all_ system calls.  I also added escaping of #
              	characters here to avoid confusing Itpl.
              	* IPython/Magic.py (shlex_split): removed call to shell in
              	parse_options and replaced it with shlex.split().  The annoying
              	part was that in Python 2.2, shlex.split() doesn't exist, so I had
              	to backport it from 2.3, with several frail hacks (the shlex
              	module is rather limited in 2.2).  Thanks to a suggestion by Ville
              	Vainio <vivainio@kolumbus.fi>.  For Python 2.3 there should be no
              	problem.
              	(Magic.magic_system_verbose): new toggle to print the actual
              	system calls made by ipython.  Mainly for debugging purposes.
              	* IPython/GnuplotRuntime.py (gnu_out): fix bug for cygwin, which
              	doesn't support persistence.  Reported (and fix suggested) by
              	Travis Caldwell <travis_caldwell2000@yahoo.com>.
 -06-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.log): fix to handle correctly empty
              	continue prompts.
              	* IPython/Extensions/InterpreterExec.py (pysh): moved the pysh()
              	function (basically a big docstring) and a few more things here to
              	speedup startup. pysh.py is now very lightweight.  We want because
              	it gets execfile'd, while InterpreterExec gets imported, so
              	byte-compilation saves time.
 -06-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_cd): Fixed to restore usage of 'cd
              	-NUM', which was recently broken.
              	* IPython/iplib.py (InteractiveShell.handle_shell_escape): allow !
              	in multi-line input (but not !!, which doesn't make sense there).
              	* IPython/UserConfig/ipythonrc: made autoindent on by default.
              	It's just too useful, and people can turn it off in the less
              	common cases where it's a problem.
 -06-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): big change -
              	special syntaxes (like alias calling) is now allied in multi-line
              	input.  This is still _very_ experimental, but it's necessary for
              	efficient shell usage combining python looping syntax with system
              	calls.  For now it's restricted to aliases, I don't think it
              	really even makes sense to have this for magics.
 -06-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Extensions/InterpreterExec.py (prefilter_shell): Added
              	$var=cmd <=> @sc var=cmd and  $$var=cmd <=> @sc -l var=cmd.
              	* IPython/Magic.py (Magic.magic_rehashx): modified to handle
              	extensions under Windows (after code sent by Gary Bishop).  The
              	extensions considered 'executable' are stored in IPython's rc
              	structure as win_exec_ext.
              	* IPython/genutils.py (shell): new function, like system() but
              	without return value.  Very useful for interactive shell work.
              	* IPython/Magic.py (Magic.magic_unalias): New @unalias function to
              	delete aliases.
              	* IPython/iplib.py (InteractiveShell.alias_table_update): make
              	sure that the alias table doesn't contain python keywords.
 -06-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_rehash): Fix crash when
              	non-existent items are found in $PATH.  Reported by Thorsten.
 -06-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (complete): modified the completer so that the
              	order of priorities can be easily changed at runtime.
              	* IPython/Extensions/InterpreterExec.py (prefilter_shell):
              	Modified to auto-execute all lines beginning with '~', '/' or '.'.
              	* IPython/Magic.py (Magic.magic_sx): modified @sc and @sx to
              	expand Python variables prepended with $ in all system calls.  The
              	same was done to InteractiveShell.handle_shell_escape.  Now all
              	system access mechanisms (!, !!, @sc, @sx and aliases) allow the
              	expansion of python variables and expressions according to the
              	syntax of PEP-215 - http://www.python.org/peps/pep-0215.html.
              	Though PEP-215 has been rejected, a similar (but simpler) one
              	seems like it will go into Python 2.4, PEP-292 -
              	http://www.python.org/peps/pep-0292.html.
              	I'll keep the full syntax of PEP-215, since IPython has since the
              	start used Ka-Ping Yee's reference implementation discussed there
              	(Itpl), and I actually like the powerful semantics it offers.
              	In order to access normal shell variables, the $ has to be escaped
              	via an extra $.  For example:
              	In [7]: PATH='a python variable'
              	In [8]: !echo $PATH
              	a python variable
              	In [9]: !echo $$PATH
              	/usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin:...
              	(Magic.parse_options): escape $ so the shell doesn't evaluate
              	things prematurely.
              	* IPython/iplib.py (InteractiveShell.call_alias): added the
              	ability for aliases to expand python variables via $.
              	* IPython/Magic.py (Magic.magic_rehash): based on the new alias
              	system, now there's a @rehash/@rehashx pair of magics.  These work
              	like the csh rehash command, and can be invoked at any time.  They
              	build a table of aliases to everything in the user's $PATH
              	(@rehash uses everything, @rehashx is slower but only adds
              	executable files).  With this, the pysh.py-based shell profile can
              	now simply call rehash upon startup, and full access to all
              	programs in the user's path is obtained.
              	* IPython/iplib.py (InteractiveShell.call_alias): The new alias
              	functionality is now fully in place.  I removed the old dynamic
              	code generation based approach, in favor of a much lighter one
              	based on a simple dict.  The advantage is that this allows me to
              	now have thousands of aliases with negligible cost (unthinkable
              	with the old system).
 -06-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (__init__): extended MagicCompleter class to
              	also complete (last in priority) on user aliases.
              	* IPython/Itpl.py (Itpl.__str__): fixed order of globals/locals in
              	call to eval.
              	(ItplNS.__init__): Added a new class which functions like Itpl,
              	but allows configuring the namespace for the evaluation to occur
              	in.
 -06-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.runcode): modify to print a
              	better message when 'exit' or 'quit' are typed (a common newbie
              	confusion).
              	* IPython/Magic.py (Magic.magic_colors): Added the runtime color
              	check for Windows users.
              	* IPython/iplib.py (InteractiveShell.user_setup): removed
              	disabling of colors for Windows.  I'll test at runtime and issue a
              	warning if Gary's readline isn't found, as to nudge users to
              	download it.
 -06-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (Stream.__init__): changed to print errors
              	to sys.stderr.  I had a circular dependency here.  Now it's
              	possible to run ipython as IDLE's shell (consider this pre-alpha,
              	since true stdout things end up in the starting terminal instead
              	of IDLE's out).
              	* IPython/Prompts.py (Prompt2.set_colors): prevent crashes for
              	users who haven't # updated their prompt_in2 definitions.  Remove
              	eventually.
              	(multiple_replace): added credit to original ASPN recipe.
 -06-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): add 'cp' to the
              	list of auto-defined aliases.
 -06-13  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (scriptfiles): Don't trigger win_post_install unless an
              	install was really requested (so setup.py can be used for other
              	things under Windows).
 -06-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.create_log): Manually remove any old
              	backup, since os.remove may fail under Windows.  Fixes bug
              	reported by Thorsten.
 -06-09  Fernando Perez  <fperez@colorado.edu>
              	* examples/example-embed.py: fixed all references to %n (replaced
              	with \\# for ps1/out prompts and with \\D for ps2 prompts).  Done
              	for all examples and the manual as well.
 -06-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (Prompt2.set_p_str): fixed all prompt
              	alignment and color management.  All 3 prompt subsystems now
              	inherit from BasePrompt.
              	* tools/release: updates for windows installer build and tag rpms
              	with python version (since paths are fixed).
              	* IPython/UserConfig/ipythonrc: modified to use \# instead of %n,
              	which will become eventually obsolete.  Also fixed the default
              	prompt_in2 to use \D, so at least new users start with the correct
              	defaults.
              	WARNING: Users with existing ipythonrc files will need to apply
              	this fix manually!
              	* setup.py: make windows installer (.exe).  This is finally the
              	integration of an old patch by Cory Dodt <dodt-AT-fcoe.k12.ca.us>,
              	which I hadn't included because it required Python 2.3 (or recent
              	distutils).
              	* IPython/usage.py (__doc__): update docs (and manpage) to reflect
              	usage of new '\D' escape.
              	* IPython/Prompts.py (ROOT_SYMBOL): Small fix for Windows (which
              	lacks os.getuid())
              	(CachedOutput.set_colors): Added the ability to turn coloring
              	on/off with @colors even for manually defined prompt colors.  It
              	uses a nasty global, but it works safely and via the generic color
              	handling mechanism.
              	(Prompt2.__init__): Introduced new escape '\D' for continuation
              	prompts. It represents the counter ('\#') as dots.
              	*** NOTE *** THIS IS A BACKWARDS-INCOMPATIBLE CHANGE.  Users will
              	need to update their ipythonrc files and replace '%n' with '\D' in
              	their prompt_in2 settings everywhere.  Sorry, but there's
              	otherwise no clean way to get all prompts to properly align.  The
              	ipythonrc shipped with IPython has been updated.
 -06-07  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (isfile): Pass local_icons option to latex2html, so the
              	resulting HTML file is self-contained.  Thanks to
              	dryice-AT-liu.com.cn for the tip.
              	* pysh.py: I created a new profile 'shell', which implements a
              	_rudimentary_ IPython-based shell.  This is in NO WAY a realy
              	system shell, nor will it become one anytime soon.  It's mainly
              	meant to illustrate the use of the new flexible bash-like prompts.
              	I guess it could be used by hardy souls for true shell management,
              	but it's no tcsh/bash...  pysh.py is loaded by the 'shell'
              	profile.  This uses the InterpreterExec extension provided by
              	W.J. van der Laan <gnufnork-AT-hetdigitalegat.nl>
              	* IPython/Prompts.py (PromptOut.__str__): now it will correctly
              	auto-align itself with the length of the previous input prompt
              	(taking into account the invisible color escapes).
              	(CachedOutput.__init__): Large restructuring of this class.  Now
              	all three prompts (primary1, primary2, output) are proper objects,
              	managed by the 'parent' CachedOutput class.  The code is still a
              	bit hackish (all prompts share state via a pointer to the cache),
              	but it's overall far cleaner than before.
              	* IPython/genutils.py (getoutputerror): modified to add verbose,
              	debug and header options.  This makes the interface of all getout*
              	functions uniform.
              	(SystemExec.getoutputerror): added getoutputerror to SystemExec.
              	* IPython/Magic.py (Magic.default_option): added a function to
              	allow registering default options for any magic command.  This
              	makes it easy to have profiles which customize the magics globally
              	for a certain use.  The values set through this function are
              	picked up by the parse_options() method, which all magics should
              	use to parse their options.
              	* IPython/genutils.py (warn): modified the warnings framework to
              	use the Term I/O class.  I'm trying to slowly unify all of
              	IPython's I/O operations to pass through Term.
              	* IPython/Prompts.py (Prompt2._str_other): Added functionality in
              	the secondary prompt to correctly match the length of the primary
              	one for any prompt.  Now multi-line code will properly line up
              	even for path dependent prompts, such as the new ones available
              	via the prompt_specials.
 -06-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (prompt_specials): Added the ability to have
              	bash-like special sequences in the prompts, which get
              	automatically expanded.  Things like hostname, current working
              	directory and username are implemented already, but it's easy to
              	add more in the future.  Thanks to a patch by W.J. van der Laan
              	<gnufnork-AT-hetdigitalegat.nl>
              	(prompt_specials): Added color support for prompt strings, so
              	users can define arbitrary color setups for their prompts.
 -06-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (Term.reopen_all): Added Windows-specific
              	code to load Gary Bishop's readline and configure it
              	automatically.  Thanks to Gary for help on this.
 -06-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.create_log): fix bug for logging
              	with no filename (previous fix was incomplete).
 -05-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.parse_options): fix bug where naked
              	parens would get passed to the shell.
 -05-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_prun): changed default profile
              	sort order to 'time' (the more common profiling need).
              	* IPython/OInspect.py (Inspector.pinfo): flush the inspect cache
              	so that source code shown is guaranteed in sync with the file on
              	disk (also changed in psource).  Similar fix to the one for
              	ultraTB on 2004-05-06.  Thanks to a bug report by Yann Le Du
              	<yann.ledu-AT-noos.fr>.
              	* IPython/Magic.py (Magic.parse_options): Fixed bug where commands
              	with a single option would not be correctly parsed. Closes
              	http://www.scipy.net/roundup/ipython/issue14.  This bug had been
              	introduced in 0.6.0 (on 2004-05-06).
 -05-13  *** Released version 0.6.0
 -05-13  Fernando Perez  <fperez@colorado.edu>
              	* debian/: Added debian/ directory to CVS, so that debian support
              	is publicly accessible.  The debian package is maintained by Jack
              	Moffit <jack-AT-xiph.org>.
              	* Documentation: included the notes about an ipython-based system
              	shell (the hypothetical 'pysh') into the new_design.pdf document,
              	so that these ideas get distributed to users along with the
              	official documentation.
 -05-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.create_log): fix recently introduced
              	bug (misindented line) where logstart would fail when not given an
              	explicit filename.
 -05-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.parse_options): skip system call when
              	there are no options to look for.  Faster, cleaner for the common
              	case.
              	* Documentation: many updates to the manual: describing Windows
              	support better, Gnuplot updates, credits, misc small stuff.  Also
              	updated the new_design doc a bit.
 -05-06  *** Released version 0.6.0.rc1
 -05-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (ListTB.text): modified a ton of string +=
              	operations to use the vastly more efficient list/''.join() method.
              	(FormattedTB.text): Fix
              	http://www.scipy.net/roundup/ipython/issue12 - exception source
              	extract not updated after reload.  Thanks to Mike Salib
              	<msalib-AT-mit.edu> for pinning the source of the problem.
              	Fortunately, the solution works inside ipython and doesn't require
              	any changes to python proper.
              	* IPython/Magic.py (Magic.parse_options): Improved to process the
              	argument list as a true shell would (by actually using the
              	underlying system shell).  This way, all @magics automatically get
              	shell expansion for variables.  Thanks to a comment by Alex
              	Schmolck.
 -04-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): Added a special
              	trap for a debugger quit exception, which is basically impossible
              	to handle by normal mechanisms, given what pdb does to the stack.
              	This fixes a crash reported by <fgibbons-AT-llama.med.harvard.edu>.
 -04-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (Term): Standardized the names of the Term
              	class streams to cin/cout/cerr, following C++ naming conventions
              	(I can't use in/out/err because 'in' is not a valid attribute
              	name).
              	* IPython/iplib.py (InteractiveShell.interact): don't increment
              	the prompt if there's no user input.  By Daniel 'Dang' Griffith
              	<pythondev-dang-AT-lazytwinacres.net>, after a suggestion from
              	Francois Pinard.
 -04-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (Stream.__init__): Modified to survive at
              	least importing in contexts where stdin/out/err aren't true file
              	objects, such as PyCrust (they lack fileno() and mode).  However,
              	the recovery facilities which rely on these things existing will
              	not work.
 -04-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_sx): modified (as well as @sc) to
              	use the new getoutputerror() function, so it properly
              	distinguishes stdout/err.
              	* IPython/genutils.py (getoutputerror): added a function to
              	capture separately the standard output and error of a command.
              	After a comment from dang on the mailing lists.  This code is
              	basically a modified version of commands.getstatusoutput(), from
              	the standard library.
              	* IPython/iplib.py (InteractiveShell.handle_shell_escape): added
              	'!!' as a special syntax (shorthand) to access @sx.
              	* IPython/Magic.py (Magic.magic_sx): new magic, to execute a shell
              	command and return its output as a list split on '\n'.
 -03-31  Fernando Perez  <fperez@colorado.edu>
              	* IPython/FakeModule.py (FakeModule.__init__): added __nonzero__
              	method to dictionaries used as FakeModule instances if they lack
              	it.  At least pydoc in python2.3 breaks for runtime-defined
              	functions without this hack.  At some point I need to _really_
              	understand what FakeModule is doing, because it's a gross hack.
              	But it solves Arnd's problem for now...
 -02-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.create_log): Fix bug where 'rotate'
              	mode would behave erratically.  Also increased the number of
              	possible logs in rotate mod to 999.  Thanks to Rod Holland
              	<rhh@StructureLABS.com> for the report and fixes.
 -02-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page): Check that the curses module really
              	has the initscr attribute before trying to use it.  For some
              	reason, the Solaris curses module is missing this.  I think this
              	should be considered a Solaris python bug, but I'm not sure.
 -01-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (Stream.__init__): Changes to try to make
              	ipython robust against stdin/out/err being closed by the user.
              	This is 'user error' (and blocks a normal python session, at least
              	the stdout case).  However, Ipython should be able to survive such
              	instances of abuse as gracefully as possible.  To simplify the
              	coding and maintain compatibility with Gary Bishop's Term
              	contributions, I've made use of classmethods for this.  I think
              	this introduces a dependency on python 2.2.
 -01-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (exp_safe): simplified the code a bit and
              	removed the need for importing the kinds module altogether.
 -01-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_sc): Made the shell capture system
              	a magic function instead, after some community feedback.  No
              	special syntax will exist for it, but its name is deliberately
              	very short.
 -12-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.handle_shell_assign): Added
              	new functionality, to automagically assign the result of a shell
              	command to a variable.  I'll solicit some community feedback on
              	this before making it permanent.
              	* IPython/OInspect.py (Inspector.pinfo): Fix crash when info was
              	requested about callables for which inspect couldn't obtain a
              	proper argspec.  Thanks to a crash report sent by Etienne
              	Posthumus <etienne-AT-apple01.cs.vu.nl>.
 -12-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page): patch for the pager to work across
              	various versions of Windows.  By Gary Bishop.
 -12-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Gnuplot2.py (PlotItems): Fixes for working with
              	Gnuplot.py version 1.7, whose internal names changed quite a bit.
              	While I tested this and it looks ok, there may still be corner
              	cases I've missed.
 -12-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): Fixed a bug
              	where a line like 'p,q=1,2' would fail because the automagic
              	system would be triggered for @p.
              	* IPython/DPyGetOpt.py (DPyGetOpt.processArguments): Tab-related
              	cleanups, code unmodified.
              	* IPython/genutils.py (Term): added a class for IPython to handle
              	output.  In most cases it will just be a proxy for stdout/err, but
              	having this allows modifications to be made for some platforms,
              	such as handling color escapes under Windows.  All of this code
              	was contributed by Gary Bishop, with minor modifications by me.
              	The actual changes affect many files.
 -11-30  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (file_matches): new completion code, courtesy
              	of Jeff Collins.  This enables filename completion again under
              	python 2.3, which disabled it at the C level.
 -11-11  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (amap): Added amap() fn.  Simple shorthand
              	for Numeric.array(map(...)), but often convenient.
 -11-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (frange): Changed a call from int() to
              	int(round()) to prevent a problem reported with arange() in the
              	numpy list.
 -10-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/DPyGetOpt.py (DPyGetOpt.processArguments): changed to
              	prevent crashes if sys lacks an argv attribute (it happens with
              	embedded interpreters which build a bare-bones sys module).
              	Thanks to a report/bugfix by Adam Hupp <hupp-AT-cs.wisc.edu>.
 -09-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic._ofind): blanket except around getattr()
              	to protect against poorly written user objects where __getattr__
              	raises exceptions other than AttributeError.  Thanks to a bug
              	report by Oliver Sander <osander-AT-gmx.de>.
              	* IPython/FakeModule.py (FakeModule.__repr__): this method was
              	missing.  Thanks to bug report by Ralf Schmitt <ralf-AT-brainbot.com>.
 -09-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): fix bug where
              	unpacking a list whith a callable as first element would
              	mistakenly trigger autocalling.  Thanks to a bug report by Jeffery
              	Collins.
 -08-25  *** Released version 0.5.0
 -08-22  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.linereader): Improved handling of
              	improperly defined user exceptions.  Thanks to feedback from Mark
              	Russell <mrussell-AT-verio.net>.
 -08-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/OInspect.py (Inspector.pinfo): changed String Form
              	printing so that it would print multi-line string forms starting
              	with a new line.  This way the formatting is better respected for
              	objects which work hard to make nice string forms.
              	* IPython/iplib.py (InteractiveShell.handle_auto): Fix bug where
              	autocall would overtake data access for objects with both
              	__getitem__ and __call__.
 -08-19  *** Released version 0.5.0-rc1
 -08-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/deep_reload.py (load_tail): single tiny change here
              	seems to fix the long-standing bug of dreload() failing to work
              	for dotted names.  But this module is pretty tricky, so I may have
              	missed some subtlety.  Needs more testing!.
              	* IPython/ultraTB.py (VerboseTB.linereader): harden against user
              	exceptions which have badly implemented __str__ methods.
              	(VerboseTB.text): harden against inspect.getinnerframes crashing,
              	which I've been getting reports about from Python 2.3 users.  I
              	wish I had a simple test case to reproduce the problem, so I could
              	either write a cleaner workaround or file a bug report if
              	necessary.
              	* IPython/Magic.py (Magic.magic_edit): fixed bug where after
              	making a class 'foo', file 'foo.py' couldn't be edited.  Thanks to
              	a bug report by Tjabo Kloppenburg.
              	* IPython/ultraTB.py (VerboseTB.debugger): hardened against pdb
              	crashes.  Wrapped the pdb call in a blanket try/except, since pdb
              	seems rather unstable.  Thanks to a bug report by Tjabo
              	Kloppenburg <tjabo.kloppenburg-AT-unix-ag.uni-siegen.de>.
              	* IPython/Release.py (version): release 0.5.0-rc1.  I want to put
              	this out soon because of the critical fixes in the inner loop for
              	generators.
              	* IPython/Magic.py (Magic.getargspec): removed.  This (and
              	_get_def) have been obsoleted by OInspect for a long time, I
              	hadn't noticed that they were dead code.
              	(Magic._ofind): restored _ofind functionality for a few literals
              	(those in ["''",'""','[]','{}','()']).  But it won't work anymore
              	for things like "hello".capitalize?, since that would require a
              	potentially dangerous eval() again.
              	* IPython/iplib.py (InteractiveShell._prefilter): reorganized the
              	logic a bit more to clean up the escapes handling and minimize the
              	use of _ofind to only necessary cases.  The interactive 'feel' of
              	IPython should have improved quite a bit with the changes in
              	_prefilter and _ofind (besides being far safer than before).
              	* IPython/Magic.py (Magic.magic_edit): Fixed old bug (but rather
              	obscure, never reported).  Edit would fail to find the object to
              	edit under some circumstances.
              	(Magic._ofind): CRITICAL FIX.  Finally removed the eval() calls
              	which were causing double-calling of generators.  Those eval calls
              	were _very_ dangerous, since code with side effects could be
              	triggered.  As they say, 'eval is evil'...  These were the
              	nastiest evals in IPython.  Besides, _ofind is now far simpler,
              	and it should also be quite a bit faster.  Its use of inspect is
              	also safer, so perhaps some of the inspect-related crashes I've
              	seen lately with Python 2.3 might be taken care of.  That will
              	need more testing.
 -08-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): significant
              	simplifications to the logic for handling user escapes.  Faster
              	and simpler code.
 -08-14  Fernando Perez  <fperez@colorado.edu>
                      * IPython/numutils.py (sum_flat): rewrote to be non-recursive.
                      Now it requires O(N) storage (N=size(a)) for non-contiguous input,
                      but it should be quite a bit faster.  And the recursive version
                      generated O(log N) intermediate storage for all rank>1 arrays,
                      even if they were contiguous.
                      (l1norm): Added this function.
                      (norm):  Added this function for arbitrary norms (including
                      l-infinity).  l1 and l2 are still special cases for convenience
                      and speed.
 -08-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_edit): Removed all remaining string
              	exceptions, which now raise PendingDeprecationWarnings in Python
 .3.  There were some in Magic and some in Gnuplot2.
 -06-30  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page): modified to call curses only for
              	terminals where TERM=='xterm'.  After problems under many other
              	terminals were reported by Keith Beattie <KSBeattie-AT-lbl.gov>.
              	* IPython/iplib.py (complete): removed spurious 'print "IE"' which
              	would be triggered when readline was absent.  This was just an old
              	debugging statement I'd forgotten to take out.
 -06-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (clock): modified to return only user time
              	(not counting system time), after a discussion on scipy.  While
              	system time may be a useful quantity occasionally, it may much
              	more easily be skewed by occasional swapping or other similar
              	activity.
 -06-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (identity): new function, for building
              	arbitrary rank Kronecker deltas (mostly backwards compatible with
              	Numeric.identity)
 -06-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.handle_magic): protect
              	arguments passed to magics with spaces, to allow trailing '\' to
              	work normally (mainly for Windows users).
 -05-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): Load site._Helper() as help
              	instead of pydoc.help.  This fixes a bizarre behavior where
              	printing '%s' % locals() would trigger the help system.  Now
              	ipython behaves like normal python does.
              	Note that if one does 'from pydoc import help', the bizarre
              	behavior returns, but this will also happen in normal python, so
              	it's not an ipython bug anymore (it has to do with how pydoc.help
              	is implemented).
 -05-22  Fernando Perez  <fperez@colorado.edu>
              	* IPython/FlexCompleter.py (Completer.attr_matches): fixed to
              	return [] instead of None when nothing matches, also match to end
              	of line.  Patch by Gary Bishop.
              	* IPython/ipmaker.py (make_IPython): Added same sys.excepthook
              	protection as before, for files passed on the command line.  This
              	prevents the CrashHandler from kicking in if user files call into
              	sys.excepthook (such as PyQt and WxWindows have a nasty habit of
              	doing).  After a report by Kasper Souren <Kasper.Souren-AT-ircam.fr>
 -05-20  *** Released version 0.4.0
 -05-20  Fernando Perez  <fperez@colorado.edu>
              	* setup.py: added support for manpages.  It's a bit hackish b/c of
              	a bug in the way the bdist_rpm distutils target handles gzipped
              	manpages, but it works.  After a patch by Jack.
 -05-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py: added a mockup of the kinds module, since
              	it was recently removed from Numeric.  This way, numutils will
              	work for all users even if they are missing kinds.
              	* IPython/Magic.py (Magic._ofind): Harden against an inspect
              	failure, which can occur with SWIG-wrapped extensions.  After a
              	crash report from Prabhu.
 -05-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.excepthook): New method to
              	protect ipython from user code which may call directly
              	sys.excepthook (this looks like an ipython crash to the user, even
              	when it isn't).  After a patch by Gary Bishop <gb-AT-cs.unc.edu>.
              	This is especially important to help users of WxWindows, but may
              	also be useful in other cases.
              	* IPython/ultraTB.py (AutoFormattedTB.__call__): Changed to allow
              	an optional tb_offset to be specified, and to preserve exception
              	info if given.  After a patch by Gary Bishop <gb-AT-cs.unc.edu>.
              	* ipython.1 (Default): Thanks to Jack's work, we now have manpages!
 -05-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.user_setup): Fix crash when
              	installing for a new user under Windows.
 -05-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.handle_emacs): New line
              	handler for Emacs comint-based lines.  Currently it doesn't do
              	much (but importantly, it doesn't update the history cache).  In
              	the future it may be expanded if Alex needs more functionality
              	there.
              	* IPython/CrashHandler.py (CrashHandler.__call__): Added platform
              	info to crash reports.
              	* IPython/iplib.py (InteractiveShell.mainloop): Added -c option,
              	just like Python's -c.  Also fixed crash with invalid -color
              	option value at startup. Thanks to Will French
              	<wfrench-AT-bestweb.net> for the bug report.
 -05-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (EvalDict.__getitem__): Renamed EvalString
              	to EvalDict (it's a mapping, after all) and simplified its code
              	quite a bit, after a nice discussion on c.l.py where Gustavo
              	Córdova <gcordova-AT-sismex.com> suggested the new version.
 -04-30  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (timings_out): modified it to reduce its
              	overhead in the common reps==1 case.
 -04-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (timings_out): Modified to use the resource
              	module, which avoids the wraparound problems of time.clock().
 -04-17  *** Released version 0.2.15pre4
 -04-17  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (scriptfiles): Split windows-specific stuff over to a
              	separate file, in an attempt to have a Windows GUI installer.
              	That didn't work, but part of the groundwork is done.
              	* IPython/UserConfig/ipythonrc: Added M-i, M-o and M-I for
              	indent/unindent with 4 spaces.  Particularly useful in combination
              	with the new auto-indent option.
 -04-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py: various replacements of self.rc for
              	self.shell.rc.  A lot more remains to be done to fully disentangle
              	this class from the main Shell class.
              	* IPython/GnuplotRuntime.py: added checks for mouse support so
              	that we don't try to enable it if the current gnuplot doesn't
              	really support it.  Also added checks so that we don't try to
              	enable persist under Windows (where Gnuplot doesn't recognize the
              	option).
              	* IPython/iplib.py (InteractiveShell.interact): Added optional
              	auto-indenting code, after a patch by King C. Shu
              	<kingshu-AT-myrealbox.com>. It's off by default because it doesn't
              	get along well with pasting indented code.  If I ever figure out
              	how to make that part go well, it will become on by default.
              	* IPython/Prompts.py (Prompt1.auto_rewrite): Fixed bug which would
              	crash ipython if there was an unmatched '%' in the user's prompt
              	string.  Reported by Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
              	* IPython/iplib.py (InteractiveShell.interact): removed the
              	ability to ask the user whether he wants to crash or not at the
              	'last line' exception handler.  Calling functions at that point
              	changes the stack, and the error reports would have incorrect
              	tracebacks.
              	* IPython/Magic.py (Magic.magic_page): Added new @page magic, to
              	pass through a peger a pretty-printed form of any object.  After a
              	contribution by Olivier Aubert <oaubert-AT-bat710.univ-lyon1.fr>
 -04-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.user_setup): Fixed bug where
              	all files in ~ would be modified at first install (instead of
              	~/.ipython).  This could be potentially disastrous, as the
              	modification (make line-endings native) could damage binary files.
 -04-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.handle_help): Modified to
              	handle only lines which are invalid python.  This now means that
              	lines like 'x=1 #?' execute properly.  Thanks to Jeffery Collins
              	for the bug report.
 -04-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.showtraceback): Fixed bug
              	where failing to set sys.last_traceback would crash pdb.pm().
              	Thanks to Jeffery D. Collins <Jeff.Collins-AT-vexcel.com> for the bug
              	report.
 -03-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_prun): rstrip() output of profiler
              	before printing it (it had a lot of spurious blank lines at the
              	end).
              	* IPython/Gnuplot2.py (Gnuplot.hardcopy): fixed bug where lpr
              	output would be sent 21 times!  Obviously people don't use this
              	too often, or I would have heard about it.
 -03-24  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (scriptfiles): renamed the data_files parameter from
              	'base' to 'data' to fix rpm build issues.  Thanks to Ralf Ahlbrink
              	for the patch.
 -03-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (error): added error() and fatal()
              	functions.
 -03-18  *** Released version 0.2.15pre3
 -03-18  Fernando Perez  <fperez@colorado.edu>
              	* setupext/install_data_ext.py
              	(install_data_ext.initialize_options): Class contributed by Jack
              	Moffit for fixing the old distutils hack.  He is sending this to
              	the distutils folks so in the future we may not need it as a
              	private fix.
              	* MANIFEST.in: Extensive reorganization, based on Jack Moffit's
              	changes for Debian packaging.  See his patch for full details.
              	The old distutils hack of making the ipythonrc* files carry a
              	bogus .py extension is gone, at last.  Examples were moved to a
              	separate subdir under doc/, and the separate executable scripts
              	now live in their own directory.  Overall a great cleanup.  The
              	manual was updated to use the new files, and setup.py has been
              	fixed for this setup.
              	* IPython/PyColorize.py (Parser.usage): made non-executable and
              	created a pycolor wrapper around it to be included as a script.
 -03-12  *** Released version 0.2.15pre2
 -03-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ColorANSI.py (make_color_table): Finally fixed the
              	long-standing problem with garbage characters in some terminals.
              	The issue was really that the \001 and \002 escapes must _only_ be
              	passed to input prompts (which call readline), but _never_ to
              	normal text to be printed on screen.  I changed ColorANSI to have
              	two classes: TermColors and InputTermColors, each with the
              	appropriate escapes for input prompts or normal text.  The code in
              	Prompts.py got slightly more complicated, but this very old and
              	annoying bug is finally fixed.
              	All the credit for nailing down the real origin of this problem
              	and the correct solution goes to Jack Moffit <jack-AT-xiph.org>.
              	*Many* thanks to him for spending quite a bit of effort on this.
 -03-05  *** Released version 0.2.15pre1
 -03-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/FakeModule.py: Moved the former _FakeModule to a
              	separate file, because it's also needed by Magic (to fix a similar
              	pickle-related issue in @run).
 -03-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_autocall): new magic to control
              	the autocall option at runtime.
              	(Magic.magic_dhist): changed self.user_ns to self.shell.user_ns
              	across Magic.py to start separating Magic from InteractiveShell.
              	(Magic._ofind): Fixed to return proper namespace for dotted
              	names. Before, a dotted name would always return 'not currently
              	defined', because it would find the 'parent'. s.x would be found,
              	but since 'x' isn't defined by itself, it would get confused.
              	(Magic.magic_run): Fixed pickling problems reported by Ralf
              	Ahlbrink <RAhlbrink-AT-RosenInspection.net>.  The fix was similar to
              	that I'd used when Mike Heeter reported similar issues at the
              	top-level, but now for @run.  It boils down to injecting the
              	namespace where code is being executed with something that looks
              	enough like a module to fool pickle.dump().  Since a pickle stores
              	a named reference to the importing module, we need this for
              	pickles to save something sensible.
              	* IPython/ipmaker.py (make_IPython): added an autocall option.
              	* IPython/iplib.py (InteractiveShell._prefilter): reordered all of
              	the auto-eval code.  Now autocalling is an option, and the code is
              	also vastly safer.  There is no more eval() involved at all.
 -03-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic._ofind): Changed interface to return a
              	dict with named keys instead of a tuple.
              	* IPython: Started using CVS for IPython as of 0.2.15pre1.
              	* setup.py (make_shortcut): Fixed message about directories
              	created during Windows installation (the directories were ok, just
              	the printed message was misleading).  Thanks to Chris Liechti
              	<cliechti-AT-gmx.net> for the heads up.
 -02-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): Fixed catching
              	of ValueError exception when checking for auto-execution.  This
              	one is raised by things like Numeric arrays arr.flat when the
              	array is non-contiguous.
 -01-31  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (SystemExec.bq): Fixed bug where bq would
              	not return any value at all (even though the command would get
              	executed).
              	(xsys): Flush stdout right after printing the command to ensure
              	proper ordering of commands and command output in the total
              	output.
              	(SystemExec/xsys/bq): Switched the names of xsys/bq and
              	system/getoutput as defaults.  The old ones are kept for
              	compatibility reasons, so no code which uses this library needs
              	changing.
 -01-27  *** Released version 0.2.14
 -01-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_edit): Fixed problem where
              	functions defined in previous edit sessions could not be re-edited
              	(because the temp files were immediately removed).  Now temp files
              	are removed only at IPython's exit.
              	(Magic.magic_run): Improved @run to perform shell-like expansions
              	on its arguments (~users and $VARS).  With this, @run becomes more
              	like a normal command-line.
              	* IPython/Shell.py (IPShellEmbed.__call__): Fixed a bunch of small
              	bugs related to embedding and cleaned up that code.  A fairly
              	important one was the impossibility to access the global namespace
              	through the embedded IPython (only local variables were visible).
 -01-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell._prefilter): Fixed
              	auto-calling to be a bit more conservative.  Now it doesn't get
              	triggered if any of '!=()<>' are in the rest of the input line, to
              	allow comparing callables.  Thanks to Alex for the heads up.
 -01-07  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page): fixed estimation of the number of
              	lines in a string to be paged to simply count newlines. This
              	prevents over-guessing due to embedded escape sequences. A better
              	long-term solution would involve stripping out the control chars
              	for the count, but it's potentially so expensive I just don't
              	think it's worth doing.
 -12-19  *** Released version 0.2.14pre50
 -12-19  Fernando Perez  <fperez@colorado.edu>
              	* tools/release (version): Changed release scripts to inform
              	Andrea and build a NEWS file with a list of recent changes.
              	* IPython/ColorANSI.py (__all__): changed terminal detection
              	code. Seems to work better for xterms without breaking
              	konsole. Will need more testing to determine if WinXP and Mac OSX
              	also work ok.
 -12-18  *** Released version 0.2.14pre49
 -12-18  Fernando Perez  <fperez@colorado.edu>
              	* Docs: added new info about Mac OSX, from Andrea.
              	* IPython/Gnuplot2.py (String): Added a String PlotItem class to
              	allow direct plotting of python strings whose format is the same
              	of gnuplot data files.
 -12-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): fixed default (y)
              	value of exit question to be acknowledged.
 -12-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py: removed generators, which had been added
              	by mistake in an earlier debugging run. This was causing trouble
              	to users of python 2.1.x. Thanks to Abel Daniel <abli-AT-freemail.hu>
              	for pointing this out.
 -11-17  Fernando Perez  <fperez@colorado.edu>
              	* Manual: updated the Gnuplot section.
              	* IPython/GnuplotRuntime.py: refactored a lot all this code, with
              	a much better split of what goes in Runtime and what goes in
              	Interactive.
              	* IPython/ipmaker.py: fixed bug where import_fail_info wasn't
              	being imported from iplib.
              	* IPython/GnuplotInteractive.py (magic_gpc): renamed @gp to @gpc
              	for command-passing. Now the global Gnuplot instance is called
              	'gp' instead of 'g', which was really a far too fragile and
              	common name.
              	* IPython/Gnuplot2.py (eps_fix_bbox): added this to fix broken
              	bounding boxes generated by Gnuplot for square plots.
              	* IPython/genutils.py (popkey): new function added. I should
              	suggest this on c.l.py as a dict method, it seems useful.
              	* IPython/Gnuplot2.py (Gnuplot.plot): Overhauled plot and replot
              	to transparently handle PostScript generation. MUCH better than
              	the previous plot_eps/replot_eps (which I removed now). The code
              	is also fairly clean and well documented now (including
              	docstrings).
 -11-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_edit): fixed docstring
              	(inconsistent with options).
              	* IPython/Gnuplot2.py (Gnuplot.hardcopy): hardcopy had been
              	manually disabled, I don't know why. Fixed it.
              	(Gnuplot._plot_eps): added new plot_eps/replot_eps to get directly
              	eps output.
 -11-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (ask_yes_no): trap EOF and ^C so that they
              	don't propagate up to caller. Fixes crash reported by François
              	Pinard.
 -11-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): fixed problem with writing
              	history file for new users.
              	(make_IPython): fixed bug where initial install would leave the
              	user running in the .ipython dir.
              	(make_IPython): fixed bug where config dir .ipython would be
              	created regardless of the given -ipythondir option. Thanks to Cory
              	Dodt <cdodt-AT-fcoe.k12.ca.us> for the bug report.
              	* IPython/genutils.py (ask_yes_no): new function for asking yes/no
              	type confirmations. Will need to use it in all of IPython's code
              	consistently.
              	* IPython/CrashHandler.py (CrashHandler.__call__): changed the
              	context to print 31 lines instead of the default 5. This will make
              	the crash reports extremely detailed in case the problem is in
              	libraries I don't have access to.
              	* IPython/iplib.py (InteractiveShell.interact): changed the 'last
              	line of defense' code to still crash, but giving users fair
              	warning. I don't want internal errors to go unreported: if there's
              	an internal problem, IPython should crash and generate a full
              	report.
 -11-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): added code to trap
              	otherwise uncaught exceptions which can appear if people set
              	sys.stdout to something badly broken. Thanks to a crash report
              	from henni-AT-mail.brainbot.com.
 -11-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): added
              	__IPYTHON__active to the builtins. It's a flag which goes on when
              	the interaction starts and goes off again when it stops. This
              	allows embedding code to detect being inside IPython. Before this
              	was done via __IPYTHON__, but that only shows that an IPython
              	instance has been created.
              	* IPython/Magic.py (Magic.magic_env): I realized that in a
              	UserDict, instance.data holds the data as a normal dict. So I
              	modified @env to return os.environ.data instead of rebuilding a
              	dict by hand.
 -11-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (warn): changed so that level 1 prints no
              	header. Level 2 is now the default (with 'WARNING' header, as
              	before). I think I tracked all places where changes were needed in
              	IPython, but outside code using the old level numbering may have
              	broken.
              	* IPython/iplib.py (InteractiveShell.runcode): added this to
              	handle the tracebacks in SystemExit traps correctly. The previous
              	code (through interact) was printing more of the stack than
              	necessary, showing IPython internal code to the user.
              	* IPython/UserConfig/ipythonrc.py: Made confirm_exit 1 by
              	default. Now that the default at the confirmation prompt is yes,
              	it's not so intrusive. François' argument that ipython sessions
              	tend to be complex enough not to lose them from an accidental C-d,
              	is a valid one.
              	* IPython/iplib.py (InteractiveShell.interact): added a
              	showtraceback() call to the SystemExit trap, and modified the exit
              	confirmation to have yes as the default.
              	* IPython/UserConfig/ipythonrc.py: removed 'session' option from
              	this file. It's been gone from the code for a long time, this was
              	simply leftover junk.
 -11-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/ipythonrc.py: new confirm_exit option
              	added. If set, IPython now traps EOF and asks for
              	confirmation. After a request by François Pinard.
              	* IPython/Magic.py (Magic.magic_Exit): New @Exit and @Quit instead
              	of @abort, and with a new (better) mechanism for handling the
              	exceptions.
 -10-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/usage.py (__doc__): updated the --help information and
              	the ipythonrc file to indicate that -log generates
              	./ipython.log. Also fixed the corresponding info in @logstart.
              	This and several other fixes in the manuals thanks to reports by
              	François Pinard <pinard-AT-iro.umontreal.ca>.
              	* IPython/Logger.py (Logger.switch_log): Fixed error message to
              	refer to @logstart (instead of @log, which doesn't exist).
              	* IPython/iplib.py (InteractiveShell._prefilter): fixed
              	AttributeError crash. Thanks to Christopher Armstrong
              	<radix-AT-twistedmatrix.com> for the report/fix. This bug had been
              	introduced recently (in 0.2.14pre37) with the fix to the eval
              	problem mentioned below.
 -10-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ConfigLoader.py (ConfigLoader.load): Fixes for Windows
              	installation. Thanks to Leonardo Santagada <retype-AT-terra.com.br>.
              	* IPython/iplib.py (InteractiveShell._prefilter): Many changes to
              	this function to fix a problem reported by Alex Schmolck. He saw
              	it with list comprehensions and generators, which were getting
              	called twice. The real problem was an 'eval' call in testing for
              	automagic which was evaluating the input line silently.
              	This is a potentially very nasty bug, if the input has side
              	effects which must not be repeated. The code is much cleaner now,
              	without any blanket 'except' left and with a regexp test for
              	actual function names.
              	But an eval remains, which I'm not fully comfortable with. I just
              	don't know how to find out if an expression could be a callable in
              	the user's namespace without doing an eval on the string. However
              	that string is now much more strictly checked so that no code
              	slips by, so the eval should only happen for things that can
              	really be only function/method names.
 -10-15  Fernando Perez  <fperez@colorado.edu>
              	* Updated LyX to 1.2.1 so I can work on the docs again. Added Mac
              	OSX information to main manual, removed README_Mac_OSX file from
              	distribution. Also updated credits for recent additions.
 -10-10  Fernando Perez  <fperez@colorado.edu>
              	* README_Mac_OSX: Added a README for Mac OSX users for fixing
              	terminal-related issues. Many thanks to Andrea Riciputi
              	<andrea.riciputi-AT-libero.it> for writing it.
              	* IPython/UserConfig/ipythonrc.py: Fixes to various small issues,
              	thanks to Thorsten Kampe <thorsten-AT-thorstenkampe.de>.
              	* setup.py (make_shortcut): Fixes for Windows installation. Thanks
              	to Fredrik Kant <fredrik.kant-AT-front.com> and Syver Enstad
              	<syver-en-AT-online.no> who both submitted patches for this problem.
              	* IPython/iplib.py (InteractiveShell.embed_mainloop): Patch for
              	global embedding to make sure that things don't overwrite user
              	globals accidentally. Thanks to Richard <rxe-AT-renre-europe.com>
              	* IPython/Gnuplot2.py (gp): Patch for Gnuplot.py 1.6
              	compatibility. Thanks to Hayden Callow
              	<h.callow-AT-elec.canterbury.ac.nz>
 -10-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Gnuplot2.py (PlotItem): Added 'index' option for
              	Gnuplot.File objects.
 -07-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (timing): Added timings() and timing() for
              	quick access to the most commonly needed data, the execution
              	times. Old timing() renamed to timings_out().
 -07-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShellEmbed.restore_system_completer): fixed
              	bug with nested instances disrupting the parent's tab completion.
              	* IPython/iplib.py (all_completions): Added Alex Schmolck's
              	all_completions code to begin the emacs integration.
              	* IPython/Gnuplot2.py (zip_items): Added optional 'titles'
              	argument to allow titling individual arrays when plotting.
 -07-15  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (make_shortcut): changed to retrieve the value of
              	'Program Files' directory from the registry (this value changes in
              	non-english versions of Windows). Thanks to Thomas Fanslau
              	<tfanslau-AT-gmx.de> for the report.
 -07-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.debugger): enabled workaround for
              	a bug in pdb, which crashes if a line with only whitespace is
              	entered. Bug report submitted to sourceforge.
 -07-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.nullrepr): fixed rare crash when
              	reporting exceptions (it's a bug in inspect.py, I just set a
              	workaround).
 -07-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): fixed reference to
              	__IPYTHON__ in __builtins__ to show up in user_ns.
 -07-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/GnuplotInteractive.py (magic_gp_set_default): changed
              	name from @gp_set_instance to @gp_set_default.
              	* IPython/ipmaker.py (make_IPython): default editor value set to
              	'0' (a string), to match the rc file. Otherwise will crash when
              	.strip() is called on it.
 -06-28  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.safe_execfile): fix importing
              	of files in current directory when a file is executed via
              	@run. Patch also by RA <ralf_ahlbrink-AT-web.de>.
              	* setup.py (manfiles): fix for rpm builds, submitted by RA
              	<ralf_ahlbrink-AT-web.de>. Now we have RPMs!
              	* IPython/ipmaker.py (make_IPython): fixed lookup of default
              	editor when set to '0'. Problem was, '0' evaluates to True (it's a
              	string!). A. Schmolck caught this one.
 -06-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): fixed bug when running user
              	defined files at the cmd line. __name__ wasn't being set to
              	__main__.
              	* IPython/Gnuplot2.py (zip_items): improved it so it can plot also
              	regular lists and tuples besides Numeric arrays.
              	* IPython/Prompts.py (CachedOutput.__call__): Added output
              	supression for input ending with ';'. Similar to Mathematica and
              	Matlab. The _* vars and Out[] list are still updated, just like
              	Mathematica behaves.
 -06-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ConfigLoader.py (ConfigLoader.load): fixed checking of
              	.ini extensions for profiels under Windows.
              	* IPython/OInspect.py (Inspector.pinfo): improved alignment of
              	string form. Fix contributed by Alexander Schmolck
              	<a.schmolck-AT-gmx.net>
              	* IPython/GnuplotRuntime.py (gp_new): new function. Returns a
              	pre-configured Gnuplot instance.
 -06-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py (exp_safe): new function, works around the
              	underflow problems in Numeric.
              	(log2): New fn. Safe log in base 2: returns exact integer answer
              	for exact integer powers of 2.
              	* IPython/Magic.py (get_py_filename): fixed it not expanding '~'
              	properly.
 -06-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (timing): new function like
              	Mathematica's. Similar to time_test, but returns more info.
 -06-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_save): modified @save and @r
              	according to Mike Heeter's suggestions.
 -06-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/GnuplotRuntime.py: Massive overhaul to the Gnuplot
              	system. GnuplotMagic is gone as a user-directory option. New files
              	make it easier to use all the gnuplot stuff both from external
              	programs as well as from IPython. Had to rewrite part of
              	hardcopy() b/c of a strange bug: often the ps files simply don't
              	get created, and require a repeat of the command (often several
              	times).
              	* IPython/ultraTB.py (AutoFormattedTB.__call__): changed to
              	resolve output channel at call time, so that if sys.stderr has
              	been redirected by user this gets honored.
 -06-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPShell.__init__): Changed IPythonShell to
              	IPShell. Kept a copy with the old names to avoid breaking people's
              	embedded code.
              	* IPython/ipython: simplified it to the bare minimum after
              	Holger's suggestions. Added info about how to use it in
              	PYTHONSTARTUP.
              	* IPython/Shell.py (IPythonShell): changed the options passing
              	from a string with funky %s replacements to a straight list. Maybe
              	a bit more typing, but it follows sys.argv conventions, so there's
              	less special-casing to remember.
 -06-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_r): new magic auto-repeat
              	command. Thanks to a suggestion by Mike Heeter.
              	(Magic.magic_pfile): added behavior to look at filenames if given
              	arg is not a defined object.
              	(Magic.magic_save): New @save function to save code snippets. Also
              	a Mike Heeter idea.
              	* IPython/UserConfig/GnuplotMagic.py (plot): Improvements to
              	plot() and replot(). Much more convenient now, especially for
              	interactive use.
              	* IPython/Magic.py (Magic.magic_run): Added .py automatically to
              	filenames.
 -06-02  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Struct.py (Struct.__init__): modified to admit
              	initialization via another struct.
              	* IPython/genutils.py (SystemExec.__init__): New stateful
              	interface to xsys and bq. Useful for writing system scripts.
 -05-30  Fernando Perez  <fperez@colorado.edu>
              	* MANIFEST.in: Changed docfile selection to exclude all the lyx
              	documents. This will make the user download smaller (it's getting
              	too big).
 -05-29  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (_FakeModule.__init__): New class introduced to
              	fix problems with shelve and pickle. Seems to work, but I don't
              	know if corner cases break it. Thanks to Mike Heeter
              	<korora-AT-SDF.LONESTAR.ORG> for the bug reports and test cases.
 -05-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Macro.__init__): fixed magics embedded in
              	macros having broken.
 -05-21  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_logstart): fixed recently
              	introduced logging bug: all history before logging started was
              	being written one character per line! This came from the redesign
              	of the input history as a special list which slices to strings,
              	not to lists.
 -05-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Prompts.py (CachedOutput.__init__): made the color table
              	be an attribute of all classes in this module. The design of these
              	classes needs some serious overhauling.
              	* IPython/DPyGetOpt.py (DPyGetOpt.setPosixCompliance): fixed bug
              	which was ignoring '_' in option names.
              	* IPython/ultraTB.py (FormattedTB.__init__): Changed
              	'Verbose_novars' to 'Context' and made it the new default. It's a
              	bit more readable and also safer than verbose.
              	* IPython/PyColorize.py (Parser.__call__): Fixed coloring of
              	triple-quoted strings.
              	* IPython/OInspect.py (__all__): new module exposing the object
              	introspection facilities. Now the corresponding magics are dummy
              	wrappers around this. Having this module will make it much easier
              	to put these functions into our modified pdb.
              	This new object inspector system uses the new colorizing module,
              	so source code and other things are nicely syntax highlighted.
 -05-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ColorANSI.py: Split the coloring tools into a separate
              	module so I can use them in other code easier (they were part of
              	ultraTB).
 -05-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/GnuplotMagic.py (magic_gp_set_instance):
              	fixed it to set the global 'g' also to the called instance, as
              	long as 'g' was still a gnuplot instance (so it doesn't overwrite
              	user's 'g' variables).
              	* IPython/iplib.py (InteractiveShell.__init__): Added In/Out
              	global variables (aliases to _ih,_oh) so that users which expect
              	In[5] or Out[7] to work aren't unpleasantly surprised.
              	(InputList.__getslice__): new class to allow executing slices of
              	input history directly. Very simple class, complements the use of
              	macros.
 -05-16  Fernando Perez  <fperez@colorado.edu>
              	* setup.py (docdirbase): make doc directory be just doc/IPython
              	without version numbers, it will reduce clutter for users.
              	* IPython/Magic.py (Magic.magic_run): Add explicit local dict to
              	execfile call to prevent possible memory leak. See for details:
              	http://mail.python.org/pipermail/python-list/2002-February/088476.html
 -05-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_psource): made the object
              	introspection names be more standard: pdoc, pdef, pfile and
              	psource. They all print/page their output, and it makes
              	remembering them easier. Kept old names for compatibility as
              	aliases.
 -05-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/GnuplotMagic.py: I think I finally understood
              	what the mouse problem was. The trick is to use gnuplot with temp
              	files and NOT with pipes (for data communication), because having
              	both pipes and the mouse on is bad news.
 -05-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic._ofind): fixed namespace order search
              	bug. Information would be reported about builtins even when
              	user-defined functions overrode them.
 -05-11  Fernando Perez  <fperez@colorado.edu>
              	* IPython/__init__.py (__all__): removed FlexCompleter from
              	__all__ so that things don't fail in platforms without readline.
 -05-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/__init__.py (__all__): removed numutils from __all__ b/c
              	it requires Numeric, effectively making Numeric a dependency for
              	IPython.
              	* Released 0.2.13
              	* IPython/Magic.py (Magic.magic_prun): big overhaul to the
              	profiler interface. Now all the major options from the profiler
              	module are directly supported in IPython, both for single
              	expressions (@prun) and for full programs (@run -p).
 -05-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_doc): fixed to show docstrings of
              	magic properly formatted for screen.
              	* setup.py (make_shortcut): Changed things to put pdf version in
              	doc/ instead of doc/manual (had to change lyxport a bit).
              	* IPython/Magic.py (Profile.string_stats): made profile runs go
              	through pager (they are long and a pager allows searching, saving,
              	etc.)
 -05-08  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.12
 -05-06  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_hist): small bug fixed (recently
              	introduced); 'hist n1 n2' was broken.
              	(Magic.magic_pdb): added optional on/off arguments to @pdb
              	(Magic.magic_run): added option -i to @run, which executes code in
              	the IPython namespace instead of a clean one. Also added @irun as
              	an alias to @run -i.
              	* IPython/UserConfig/GnuplotMagic.py (magic_gp_set_instance):
              	fixed (it didn't really do anything, the namespaces were wrong).
              	* IPython/Debugger.py (__init__): Added workaround for python 2.1
              	* IPython/__init__.py (__all__): Fixed package namespace, now
              	'import IPython' does give access to IPython.<all> as
              	expected. Also renamed __release__ to Release.
              	* IPython/Debugger.py (__license__): created new Pdb class which
              	functions like a drop-in for the normal pdb.Pdb but does NOT
              	import readline by default. This way it doesn't muck up IPython's
              	readline handling, and now tab-completion finally works in the
              	debugger -- sort of. It completes things globally visible, but the
              	completer doesn't track the stack as pdb walks it. That's a bit
              	tricky, and I'll have to implement it later.
 -05-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_oinfo): fixed formatting bug for
              	magic docstrings when printed via ? (explicit \'s were being
              	printed).
              	* IPython/ipmaker.py (make_IPython): fixed namespace
              	identification bug. Now variables loaded via logs or command-line
              	files are recognized in the interactive namespace by @who.
              	* IPython/iplib.py (InteractiveShell.safe_execfile): Fixed bug in
              	log replay system stemming from the string form of Structs.
              	* IPython/Magic.py (Macro.__init__): improved macros to properly
              	handle magic commands in them.
              	(Magic.magic_logstart): usernames are now expanded so 'logstart
              	~/mylog' now works.
              	* IPython/iplib.py (complete): fixed bug where paths starting with
              	'/' would be completed as magic names.
 -05-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_run): added options -p and -f to
              	allow running full programs under the profiler's control.
              	* IPython/ultraTB.py (FormattedTB.__init__): Added Verbose_novars
              	mode to report exceptions verbosely but without formatting
              	variables. This addresses the issue of ipython 'freezing' (it's
              	not frozen, but caught in an expensive formatting loop) when huge
              	variables are in the context of an exception.
              	(VerboseTB.text): Added '--->' markers at line where exception was
              	triggered. Much clearer to read, especially in NoColor modes.
              	* IPython/Magic.py (Magic.magic_run): bugfix: -n option had been
              	implemented in reverse when changing to the new parse_options().
 -05-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.parse_options): new function so that
              	magics can parse options easier.
              	(Magic.magic_prun): new function similar to profile.run(),
              	suggested by Chris Hart.
              	(Magic.magic_cd): fixed behavior so that it only changes if
              	directory actually is in history.
              	* IPython/usage.py (__doc__): added information about potential
              	slowness of Verbose exception mode when there are huge data
              	structures to be formatted (thanks to Archie Paulson).
              	* IPython/ipmaker.py (make_IPython): Changed default logging
              	(when simply called with -log) to use curr_dir/ipython.log in
              	rotate mode. Fixed crash which was occuring with -log before
              	(thanks to Jim Boyle).
 -05-01  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.11 for these fixes (mainly the ultraTB one which
              	was nasty -- though somewhat of a corner case).
              	* IPython/ultraTB.py (AutoFormattedTB.text): renamed __text to
              	text (was a bug).
 -04-30  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/GnuplotMagic.py (magic_gp): Minor fix to add
              	a print after ^D or ^C from the user so that the In[] prompt
              	doesn't over-run the gnuplot one.
 -04-29  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.10
              	* IPython/__release__.py (version): get date dynamically.
              	* Misc. documentation updates thanks to Arnd's comments. Also ran
              	a full spellcheck on the manual (hadn't been done in a while).
 -04-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_logstart): Fixed bug where
              	starting a log in mid-session would reset the input history list.
 -04-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.wait): Fixed bug where not
              	all files were being included in an update. Now anything in
              	UserConfig that matches [A-Za-z]*.py will go (this excludes
              	__init__.py)
 -04-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.__init__): Added __IPYTHON__
              	to __builtins__ so that any form of embedded or imported code can
              	test for being inside IPython.
              	* IPython/UserConfig/GnuplotMagic.py: (magic_gp_set_instance):
              	changed to GnuplotMagic because it's now an importable module,
              	this makes the name follow that of the standard Gnuplot module.
              	GnuplotMagic can now be loaded at any time in mid-session.
 -04-24  Fernando Perez  <fperez@colorado.edu>
              	* IPython/numutils.py: removed SIUnits. It doesn't properly set
              	the globals (IPython has its own namespace) and the
              	PhysicalQuantity stuff is much better anyway.
              	* IPython/UserConfig/example-gnuplot.py (g2): Added gnuplot
              	embedding example to standard user directory for
              	distribution. Also put it in the manual.
              	* IPython/numutils.py (gnuplot_exec): Changed to take a gnuplot
              	instance as first argument (so it doesn't rely on some obscure
              	hidden global).
              	* IPython/UserConfig/ipythonrc.py: put () back in accepted
              	delimiters. While it prevents ().TAB from working, it allows
              	completions in open (... expressions. This is by far a more common
              	case.
 -04-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Extensions/InterpreterPasteInput.py: new
              	syntax-processing module for pasting lines with >>> or ... at the
              	start.
              	* IPython/Extensions/PhysicalQ_Interactive.py
              	(PhysicalQuantityInteractive.__int__): fixed to work with either
              	Numeric or math.
              	* IPython/UserConfig/ipythonrc-numeric.py: reorganized the
              	provided profiles. Now we have:
              	-math -> math module as * and cmath with its own namespace.
              	-numeric -> Numeric as *, plus gnuplot & grace
              	-physics -> same as before
              	* IPython/Magic.py (Magic.magic_magic): Fixed bug where
              	user-defined magics wouldn't be found by @magic if they were
              	defined as class methods. Also cleaned up the namespace search
              	logic and the string building (to use %s instead of many repeated
              	string adds).
              	* IPython/UserConfig/example-magic.py (magic_foo): updated example
              	of user-defined magics to operate with class methods (cleaner, in
              	line with the gnuplot code).
 -04-22  Fernando Perez  <fperez@colorado.edu>
              	* setup.py: updated dependency list so that manual is updated when
              	all included files change.
              	* IPython/ipmaker.py (make_IPython): Fixed bug which was ignoring
              	the delimiter removal option (the fix is ugly right now).
              	* IPython/UserConfig/ipythonrc-physics.py: simplified not to load
              	all of the math profile (quicker loading, no conflict between
              	g-9.8 and g-gnuplot).
              	* IPython/CrashHandler.py (CrashHandler.__call__): changed default
              	name of post-mortem files to IPython_crash_report.txt.
              	* Cleanup/update of the docs. Added all the new readline info and
              	formatted all lists as 'real lists'.
              	* IPython/ipmaker.py (make_IPython): removed now-obsolete
              	tab-completion options, since the full readline parse_and_bind is
              	now accessible.
              	* IPython/iplib.py (InteractiveShell.init_readline): Changed
              	handling of readline options. Now users can specify any string to
              	be passed to parse_and_bind(), as well as the delimiters to be
              	removed.
              	(InteractiveShell.__init__): Added __name__ to the global
              	namespace so that things like Itpl which rely on its existence
              	don't crash.
              	(InteractiveShell._prefilter): Defined the default with a _ so
              	that prefilter() is easier to override, while the default one
              	remains available.
 -04-18  Fernando Perez  <fperez@colorado.edu>
              	* Added information about pdb in the docs.
 -04-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): added rc_override option to
              	allow passing config options at creation time which may override
              	anything set in the config files or command line. This is
              	particularly useful for configuring embedded instances.
 -04-15  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Logger.py (Logger.log): Fixed a nasty bug which could
              	crash embedded instances because of the input cache falling out of
              	sync with the output counter.
              	* IPython/Shell.py (IPythonShellEmbed.__init__): added a debug
              	mode which calls pdb after an uncaught exception in IPython itself.
 -04-14  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.showtraceback): pdb mucks up
              	readline, fix it back after each call.
              	* IPython/ultraTB.py (AutoFormattedTB.__text): made text a private
              	method to force all access via __call__(), which guarantees that
              	traceback references are properly deleted.
              	* IPython/Prompts.py (CachedOutput._display): minor fixes to
              	improve printing when pprint is in use.
 -04-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPythonShellEmbed.__call__): SystemExit
              	exceptions aren't caught anymore. If the user triggers one, he
              	should know why he's doing it and it should go all the way up,
              	just like any other exception. So now @abort will fully kill the
              	embedded interpreter and the embedding code (unless that happens
              	to catch SystemExit).
              	* IPython/ultraTB.py (VerboseTB.__init__): added a call_pdb flag
              	and a debugger() method to invoke the interactive pdb debugger
              	after printing exception information. Also added the corresponding
              	-pdb option and @pdb magic to control this feature, and updated
              	the docs. After a suggestion from Christopher Hart
              	(hart-AT-caltech.edu).
 -04-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPythonShellEmbed.__init__): modified to use
              	the exception handlers defined by the user (not the CrashHandler)
              	so that user exceptions don't trigger an ipython bug report.
              	* IPython/ultraTB.py (ColorTB.__init__): made the color scheme
              	configurable (it should have always been so).
 -03-26  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPythonShellEmbed.__call__): many changes here
              	and there to fix embedding namespace issues. This should all be
              	done in a more elegant way.
 -03-25  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (get_home_dir): Try to make it work under
              	win9x also.
 -03-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Shell.py (IPythonShellEmbed.__init__): leave
              	sys.displayhook untouched upon __init__.
 -03-19  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.9 (for embedding bug, basically).
              	* IPython/Shell.py (IPythonShellEmbed.__call__): Trap SystemExit
              	exceptions so that enclosing shell's state can be restored.
              	* Changed magic_gnuplot.py to magic-gnuplot.py to standardize
              	naming conventions in the .ipython/ dir.
              	* IPython/iplib.py (InteractiveShell.init_readline): removed '-'
              	from delimiters list so filenames with - in them get expanded.
              	* IPython/Shell.py (IPythonShellEmbed.__call__): fixed bug with
              	sys.displayhook not being properly restored after an embedded call.
 -03-18  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.8
              	* IPython/iplib.py (InteractiveShell.user_setup): fixed bug where
              	some files weren't being included in a -upgrade.
              	(InteractiveShell.init_readline): Added 'set show-all-if-ambiguous
              	on' so that the first tab completes.
              	(InteractiveShell.handle_magic): fixed bug with spaces around
              	quotes breaking many magic commands.
              	* setup.py: added note about ignoring the syntax error messages at
              	installation.
              	* IPython/UserConfig/magic_gnuplot.py (magic_gp): finished
              	streamlining the gnuplot interface, now there's only one magic @gp.
 -03-17  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/magic_gnuplot.py: new name for the
              	example-magic_pm.py file. Much enhanced system, now with a shell
              	for communicating directly with gnuplot, one command at a time.
              	* IPython/Magic.py (Magic.magic_run): added option -n to prevent
              	setting __name__=='__main__'.
              	* IPython/UserConfig/example-magic_pm.py (magic_pm): Added
              	mini-shell for accessing gnuplot from inside ipython. Should
              	extend it later for grace access too. Inspired by Arnd's
              	suggestion.
              	* IPython/iplib.py (InteractiveShell.handle_magic): fixed bug when
              	calling magic functions with () in their arguments. Thanks to Arnd
              	Baecker for pointing this to me.
              	* IPython/numutils.py (sum_flat): fixed bug. Would recurse
              	infinitely for integer or complex arrays (only worked with floats).
 -03-16  Fernando Perez  <fperez@colorado.edu>
              	* setup.py: Merged setup and setup_windows into a single script
              	which properly handles things for windows users.
 -03-15  Fernando Perez  <fperez@colorado.edu>
              	* Big change to the manual: now the magics are all automatically
              	documented. This information is generated from their docstrings
              	and put in a latex file included by the manual lyx file. This way
              	we get always up to date information for the magics. The manual
              	now also has proper version information, also auto-synced.
              	For this to work, an undocumented --magic_docstrings option was added.
 -03-13  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (TermColors): fixed problem with dark colors
              	under CDE terminals. An explicit ;2 color reset is needed in the escapes.
 -03-12  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (TermColors): changed color escapes again to
              	fix the (old, reintroduced) line-wrapping bug. Basically, if
              	\001..\002 aren't given in the color escapes, lines get wrapped
              	weirdly. But giving those screws up old xterms and emacs terms. So
              	I added some logic for emacs terms to be ok, but I can't identify old
              	xterms separately ($TERM=='xterm' for many terminals, like konsole).
 -03-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/usage.py (__doc__): Various documentation cleanups and
              	updates, both in usage docstrings and in the manual.
              	* IPython/Prompts.py (CachedOutput.set_colors): cleanups for
              	handling of caching. Set minimum acceptabe value for having a
              	cache at 20 values.
              	* IPython/iplib.py (InteractiveShell.user_setup): moved the
              	install_first_time function to a method, renamed it and added an
              	'upgrade' mode. Now people can update their config directory with
              	a simple command line switch (-upgrade, also new).
              	* IPython/Magic.py (Magic.magic_pfile): Made @pfile an alias to
              	@file (convenient for automagic users under Python >= 2.2).
              	Removed @files (it seemed more like a plural than an abbrev. of
              	'file show').
              	* IPython/iplib.py (install_first_time): Fixed crash if there were
              	backup files ('~') in .ipython/ install directory.
              	* IPython/ipmaker.py (make_IPython): fixes for new prompt
              	system. Things look fine, but these changes are fairly
              	intrusive. Test them for a few days.
              	* IPython/Prompts.py (CachedOutput.__init__): Massive rewrite of
              	the prompts system. Now all in/out prompt strings are user
              	controllable. This is particularly useful for embedding, as one
              	can tag embedded instances with particular prompts.
              	Also removed global use of sys.ps1/2, which now allows nested
              	embeddings without any problems. Added command-line options for
              	the prompt strings.
 -03-08  Fernando Perez  <fperez@colorado.edu>
              	* IPython/UserConfig/example-embed-short.py (ipshell): added
              	example file with the bare minimum code for embedding.
              	* IPython/Shell.py (IPythonShellEmbed.set_dummy_mode): added
              	functionality for the embeddable shell to be activated/deactivated
              	either globally or at each call.
              	* IPython/Prompts.py (Prompt1.auto_rewrite): Fixes the problem of
              	rewriting the prompt with '--->' for auto-inputs with proper
              	coloring. Now the previous UGLY hack in handle_auto() is gone, and
              	this is handled by the prompts class itself, as it should.
 -03-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython/Magic.py (Magic.magic_logstart): Changed @log to
              	@logstart to avoid name clashes with the math log function.
              	* Big updates to X/Emacs section of the manual.
              	* Removed ipython_emacs. Milan explained to me how to pass
              	arguments to ipython through Emacs. Some day I'm going to end up
              	learning some lisp...
 -03-04  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipython_emacs: Created script to be used as the
              	py-python-command Emacs variable so we can pass IPython
              	parameters. I can't figure out how to tell Emacs directly to pass
              	parameters to IPython, so a dummy shell script will do it.
              	Other enhancements made for things to work better under Emacs'
              	various types of terminals. Many thanks to Milan Zamazal
              	<pdm-AT-zamazal.org> for all the suggestions and pointers.
 -03-01  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ipmaker.py (make_IPython): added a --readline! option so
              	that loading of readline is now optional. This gives better
              	control to emacs users.
              	* IPython/ultraTB.py (__date__): Modified color escape sequences
              	and now things work fine under xterm and in Emacs' term buffers
              	(though not shell ones). Well,  in emacs you get colors, but all
              	seem to be 'light' colors (no difference between dark and light
              	ones). But the garbage chars are gone, and also in xterms. It
              	seems that now I'm using 'cleaner' ansi sequences.
 -02-21  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.7 (mainly to publish the scoping fix).
              	* IPython/Logger.py (Logger.logstate): added. A corresponding
              	@logstate magic was created.
              	* IPython/Magic.py: fixed nested scoping problem under Python
 .1.x (automagic wasn't working).
 -02-20  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.6.
              	* IPython/OutputTrap.py (OutputTrap.__init__): added a 'quiet'
              	option so that logs can come out without any headers at all.
              	* IPython/UserConfig/ipythonrc-scipy.py: created a profile for
              	SciPy.
              	* IPython/iplib.py (InteractiveShell.embed_mainloop): Changed so
              	that embedded IPython calls don't require vars() to be explicitly
              	passed. Now they are extracted from the caller's frame (code
              	snatched from Eric Jones' weave). Added better documentation to
              	the section on embedding and the example file.
              	* IPython/genutils.py (page): Changed so that under emacs, it just
              	prints the string. You can then page up and down in the emacs
              	buffer itself. This is how the builtin help() works.
              	* IPython/Prompts.py (CachedOutput.__call__): Fixed issue with
              	macro scoping: macros need to be executed in the user's namespace
              	to work as if they had been typed by the user.
              	* IPython/Magic.py (Magic.magic_macro): Changed macros so they
              	execute automatically (no need to type 'exec...'). They then
              	behave like 'true macros'. The printing system was also modified
              	for this to work.
 -02-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (page_file): new function for paging files
              	in an OS-independent way. Also necessary for file viewing to work
              	well inside Emacs buffers.
              	(page): Added checks for being in an emacs buffer.
              	(page): fixed bug for Windows ($TERM isn't set in Windows). Fixed
              	same bug in iplib.
 -02-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.init_readline): modified use
              	of readline so that IPython can work inside an Emacs buffer.
              	* IPython/ultraTB.py (AutoFormattedTB.__call__): some fixes to
              	method signatures (they weren't really bugs, but it looks cleaner
              	and keeps PyChecker happy).
              	* IPython/ipmaker.py (make_IPython): added hooks Struct to __IP
              	for implementing various user-defined hooks. Currently only
              	display is done.
              	* IPython/Prompts.py (CachedOutput._display): changed display
              	functions so that they can be dynamically changed by users easily.
              	* IPython/Extensions/numeric_formats.py (num_display): added an
              	extension for printing NumPy arrays in flexible manners. It
              	doesn't do anything yet, but all the structure is in
              	place. Ultimately the plan is to implement output format control
              	like in Octave.
              	* IPython/Magic.py (Magic.lsmagic): changed so that bound magic
              	methods are found at run-time by all the automatic machinery.
 -02-17  Fernando Perez  <fperez@colorado.edu>
              	* setup_Windows.py (make_shortcut): documented. Cleaned up the
              	whole file a little.
              	* ToDo: closed this document. Now there's a new_design.lyx
              	document for all new ideas. Added making a pdf of it for the
              	end-user distro.
              	* IPython/Logger.py (Logger.switch_log): Created this to replace
              	logon() and logoff(). It also fixes a nasty crash reported by
              	Philip Hisley <compsys-AT-starpower.net>. Many thanks to him.
              	* IPython/iplib.py (complete): got auto-completion to work with
              	automagic (I had wanted this for a long time).
              	* IPython/Magic.py (Magic.magic_files): Added @files as an alias
              	to @file, since file() is now a builtin and clashes with automagic
              	for @file.
              	* Made some new files: Prompts, CrashHandler, Magic, Logger. All
              	of this was previously in iplib, which had grown to more than 2000
              	lines, way too long. No new functionality, but it makes managing
              	the code a bit easier.
              	* IPython/iplib.py (IPythonCrashHandler.__call__): Added version
              	information to crash reports.
 -02-12  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.5.
 -02-11  Fernando Perez  <fperez@colorado.edu>
              	* Wrote a relatively complete Windows installer. It puts
              	everything in place, creates Start Menu entries and fixes the
              	color issues. Nothing fancy, but it works.
 -02-10  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.safe_execfile): added an
              	os.path.expanduser() call so that we can type @run ~/myfile.py and
              	have thigs work as expected.
              	* IPython/genutils.py (page): fixed exception handling so things
              	work both in Unix and Windows correctly. Quitting a pager triggers
              	an IOError/broken pipe in Unix, and in windows not finding a pager
              	is also an IOError, so I had to actually look at the return value
              	of the exception, not just the exception itself. Should be ok now.
              	* IPython/ultraTB.py (ColorSchemeTable.set_active_scheme):
              	modified to allow case-insensitive color scheme changes.
 -02-09  Fernando Perez  <fperez@colorado.edu>
              	* IPython/genutils.py (native_line_ends): new function to leave
              	user config files with os-native line-endings.
              	* README and manual updates.
              	* IPython/genutils.py: fixed unicode bug: use types.StringTypes
              	instead of StringType to catch Unicode strings.
              	* IPython/genutils.py (filefind): fixed bug for paths with
              	embedded spaces (very common in Windows).
              	* IPython/ipmaker.py (make_IPython): added a '.ini' to the rc
              	files under Windows, so that they get automatically associated
              	with a text editor. Windows makes it a pain to handle
              	extension-less files.
              	* IPython/iplib.py (InteractiveShell.init_readline): Made the
              	warning about readline only occur for Posix. In Windows there's no
              	way to get readline, so why bother with the warning.
              	* IPython/Struct.py (Struct.__str__): fixed to use self.__dict__
              	for __str__ instead of dir(self), since dir() changed in 2.2.
              	* Ported to Windows! Tested on XP, I suspect it should work fine
              	on NT/2000, but I don't think it will work on 98 et al. That
              	series of Windows is such a piece of junk anyway that I won't try
              	porting it there. The XP port was straightforward, showed a few
              	bugs here and there (fixed all), in particular some string
              	handling stuff which required considering Unicode strings (which
              	Windows uses). This is good, but hasn't been too tested :) No
              	fancy installer yet, I'll put a note in the manual so people at
              	least make manually a shortcut.
              	* IPython/iplib.py (Magic.magic_colors): Unified the color options
              	into a single one, "colors". This now controls both prompt and
              	exception color schemes, and can be changed both at startup
              	(either via command-line switches or via ipythonrc files) and at
              	runtime, with @colors.
              	(Magic.magic_run): renamed @prun to @run and removed the old
              	@run. The two were too similar to warrant keeping both.
 -02-03  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (install_first_time): Added comment on how to
              	configure the color options for first-time users. Put a <return>
              	request at the end so that small-terminal users get a chance to
              	read the startup info.
 -01-23  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (CachedOutput.update): Changed output memory
              	variable names from _o,_oo,_ooo,_o<n> to simply _,__,___,_<n>. For
              	input history we still use _i. Did this b/c these variable are
              	very commonly used in interactive work, so the less we need to
              	type the better off we are.
              	(Magic.magic_prun): updated @prun to better handle the namespaces
              	the file will run in, including a fix for __name__ not being set
              	before.
 -01-20  Fernando Perez  <fperez@colorado.edu>
              	* IPython/ultraTB.py (VerboseTB.linereader): Fixed printing of
              	extra garbage for Python 2.2. Need to look more carefully into
              	this later.
 -01-19  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.showtraceback): fixed to
              	display SyntaxError exceptions properly formatted when they occur
              	(they can be triggered by imported code).
 -01-18  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.safe_execfile): now
              	SyntaxError exceptions are reported nicely formatted, instead of
              	spitting out only offset information as before.
              	(Magic.magic_prun): Added the @prun function for executing
              	programs with command line args inside IPython.
 -01-16  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (Magic.magic_hist): Changed @hist and @dhist
              	to *not* include the last item given in a range. This brings their
              	behavior in line with Python's slicing:
              	  a[n1:n2] -> a[n1]...a[n2-1]
              	It may be a bit less convenient, but I prefer to stick to Python's
              	conventions *everywhere*, so users never have to wonder.
              	(Magic.magic_macro): Added @macro function to ease the creation of
              	macros.
 -01-05  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.4.
              	* IPython/iplib.py (Magic.magic_pdef):
              	(InteractiveShell.safe_execfile): report magic lines and error
              	lines without line numbers so one can easily copy/paste them for
              	re-execution.
              	* Updated manual with recent changes.
              	* IPython/iplib.py (Magic.magic_oinfo): added constructor
              	docstring printing when class? is called. Very handy for knowing
              	how to create class instances (as long as __init__ is well
              	documented, of course :)
              	(Magic.magic_doc): print both class and constructor docstrings.
              	(Magic.magic_pdef): give constructor info if passed a class and
              	__call__ info for callable object instances.
 -01-04  Fernando Perez  <fperez@colorado.edu>
              	* Made deep_reload() off by default. It doesn't always work
              	exactly as intended, so it's probably safer to have it off. It's
              	still available as dreload() anyway, so nothing is lost.
 -01-02  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.3 (contacted R.Singh at CU about biopython course,
              	so I wanted an updated release).
 -12-27  Fernando Perez  <fperez@colorado.edu>
              	* IPython/iplib.py (InteractiveShell.interact): Added the original
              	code from 'code.py' for this module in order to change the
              	handling of a KeyboardInterrupt. This was necessary b/c otherwise
              	the history cache would break when the user hit Ctrl-C, and
              	interact() offers no way to add any hooks to it.
 -12-23  Fernando Perez  <fperez@colorado.edu>
              	* setup.py: added check for 'MANIFEST' before trying to remove
              	it. Thanks to Sean Reifschneider.
 -12-22  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.2.
              	* Finished (reasonably) writing the manual. Later will add the
              	python-standard navigation stylesheets, but for the time being
              	it's fairly complete. Distribution will include html and pdf
              	versions.
              	* Bugfix: '.' wasn't being added to sys.path. Thanks to Prabhu
              	(MayaVi author).
 -12-21  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.1. Barring any nasty bugs, this is it as far as a
              	good public release, I think (with the manual and the distutils
              	installer). The manual can use some work, but that can go
              	slowly. Otherwise I think it's quite nice for end users. Next
              	summer, rewrite the guts of it...
              	* Changed format of ipythonrc files to use whitespace as the
              	separator instead of an explicit '='. Cleaner.
 -12-20  Fernando Perez  <fperez@colorado.edu>
              	* Started a manual in LyX. For now it's just a quick merge of the
              	various internal docstrings and READMEs. Later it may grow into a
              	nice, full-blown manual.
              	* Set up a distutils based installer. Installation should now be
              	trivially simple for end-users.
 -12-11  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.2.0. First public release, announced it at
              	comp.lang.python. From now on, just bugfixes...
              	* Went through all the files, set copyright/license notices and
              	cleaned up things. Ready for release.
 -12-10  Fernando Perez  <fperez@colorado.edu>
              	* Changed the first-time installer not to use tarfiles. It's more
              	robust now and less unix-dependent. Also makes it easier for
              	people to later upgrade versions.
              	* Changed @exit to @abort to reflect the fact that it's pretty
              	brutal (a sys.exit()). The difference between @abort and Ctrl-D
              	becomes significant only when IPyhton is embedded: in that case,
              	C-D closes IPython only, but @abort kills the enclosing program
              	too (unless it had called IPython inside a try catching
              	SystemExit).
              	* Created Shell module which exposes the actuall IPython Shell
              	classes, currently the normal and the embeddable one. This at
              	least offers a stable interface we won't need to change when
              	(later) the internals are rewritten. That rewrite will be confined
              	to iplib and ipmaker, but the Shell interface should remain as is.
              	* Added embed module which offers an embeddable IPShell object,
              	useful to fire up IPython *inside* a running program. Great for
              	debugging or dynamical data analysis.
 -12-08  Fernando Perez  <fperez@colorado.edu>
              	* Fixed small bug preventing seeing info from methods of defined
              	objects (incorrect namespace in _ofind()).
              	* Documentation cleanup. Moved the main usage docstrings to a
              	separate file, usage.py (cleaner to maintain, and hopefully in the
              	future some perlpod-like way of producing interactive, man and
              	html docs out of it will be found).
              	* Added @profile to see your profile at any time.
              	* Added @p as an alias for 'print'. It's especially convenient if
              	using automagic ('p x' prints x).
              	* Small cleanups and fixes after a pychecker run.
              	* Changed the @cd command to handle @cd - and @cd -<n> for
              	visiting any directory in _dh.
              	* Introduced _dh, a history of visited directories. @dhist prints
              	it out with numbers.
 -12-07  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.1.22
              	* Made initialization a bit more robust against invalid color
              	options in user input (exit, not traceback-crash).
              	* Changed the bug crash reporter to write the report only in the
              	user's .ipython directory. That way IPython won't litter people's
              	hard disks with crash files all over the place. Also print on
              	screen the necessary mail command.
              	* With the new ultraTB, implemented LightBG color scheme for light
              	background terminals. A lot of people like white backgrounds, so I
              	guess we should at least give them something readable.
 -12-06  Fernando Perez  <fperez@colorado.edu>
              	* Modified the structure of ultraTB. Now there's a proper class
              	for tables of color schemes which allow adding schemes easily and
              	switching the active scheme without creating a new instance every
              	time (which was ridiculous). The syntax for creating new schemes
              	is also cleaner. I think ultraTB is finally done, with a clean
              	class structure. Names are also much cleaner (now there's proper
              	color tables, no need for every variable to also have 'color' in
              	its name).
              	* Broke down genutils into separate files. Now genutils only
              	contains utility functions, and classes have been moved to their
              	own files (they had enough independent functionality to warrant
              	it): ConfigLoader, OutputTrap, Struct.
 -12-05  Fernando Perez  <fperez@colorado.edu>
              	* IPython turns 21! Released version 0.1.21, as a candidate for
              	public consumption. If all goes well, release in a few days.
              	* Fixed path bug (files in Extensions/ directory wouldn't be found
              	unless IPython/ was explicitly in sys.path).
              	* Extended the FlexCompleter class as MagicCompleter to allow
              	completion of @-starting lines.
              	* Created __release__.py file as a central repository for release
              	info that other files can read from.
              	* Fixed small bug in logging: when logging was turned on in
              	mid-session, old lines with special meanings (!@?) were being
              	logged without the prepended comment, which is necessary since
              	they are not truly valid python syntax. This should make session
              	restores produce less errors.
              	* The namespace cleanup forced me to make a FlexCompleter class
              	which is nothing but a ripoff of rlcompleter, but with selectable
              	namespace (rlcompleter only works in __main__.__dict__). I'll try
              	to submit a note to the authors to see if this change can be
              	incorporated in future rlcompleter releases (Dec.6: done)
              	* More fixes to namespace handling. It was a mess! Now all
              	explicit references to __main__.__dict__ are gone (except when
              	really needed) and everything is handled through the namespace
              	dicts in the IPython instance. We seem to be getting somewhere
              	with this, finally...
              	* Small documentation updates.
              	* Created the Extensions directory under IPython (with an
              	__init__.py). Put the PhysicalQ stuff there. This directory should
              	be used for all special-purpose extensions.
              	* File renaming:
              	  ipythonlib --> ipmaker
              	  ipplib     --> iplib
              	This makes a bit more sense in terms of what these files actually do.
              	* Moved all the classes and functions in ipythonlib to ipplib, so
              	now ipythonlib only has make_IPython(). This will ease up its
              	splitting in smaller functional chunks later.
              	* Cleaned up (done, I think) output of @whos. Better column
              	formatting, and now shows str(var) for as much as it can, which is
              	typically what one gets with a 'print var'.
 -12-04  Fernando Perez  <fperez@colorado.edu>
              	* Fixed namespace problems. Now builtin/IPyhton/user names get
              	properly reported in their namespace. Internal namespace handling
              	is finally getting decent (not perfect yet, but much better than
              	the ad-hoc mess we had).
              	* Removed -exit option. If people just want to run a python
              	script, that's what the normal interpreter is for. Less
              	unnecessary options, less chances for bugs.
              	* Added a crash handler which generates a complete post-mortem if
              	IPython crashes. This will help a lot in tracking bugs down the
              	road.
              	* Fixed nasty bug in auto-evaluation part of prefilter(). Names
              	which were boud to functions being reassigned would bypass the
              	logger, breaking the sync of _il with the prompt counter. This
              	would then crash IPython later when a new line was logged.
 -12-02  Fernando Perez  <fperez@colorado.edu>
              	* Made IPython a package. This means people don't have to clutter
              	their sys.path with yet another directory. Changed the INSTALL
              	file accordingly.
              	* Cleaned up the output of @who_ls, @who and @whos. @who_ls now
              	sorts its output (so @who shows it sorted) and @whos formats the
              	table according to the width of the first column. Nicer, easier to
              	read. Todo: write a generic table_format() which takes a list of
              	lists and prints it nicely formatted, with optional row/column
              	separators and proper padding and justification.
              	* Released 0.1.20
              	* Fixed bug in @log which would reverse the inputcache list (a
              	copy operation was missing).
              	* Code cleanup. @config was changed to use page(). Better, since
              	its output is always quite long.
              	* Itpl is back as a dependency. I was having too many problems
              	getting the parametric aliases to work reliably, and it's just
              	easier to code weird string operations with it than playing %()s
              	games. It's only ~6k, so I don't think it's too big a deal.
              	* Found (and fixed) a very nasty bug with history. !lines weren't
              	getting cached, and the out of sync caches would crash
              	IPython. Fixed it by reorganizing the prefilter/handlers/logger
              	division of labor a bit better. Bug fixed, cleaner structure.
 -12-01  Fernando Perez  <fperez@colorado.edu>
              	* Released 0.1.19
              	* Added option -n to @hist to prevent line number printing. Much
              	easier to copy/paste code this way.
              	* Created global _il to hold the input list. Allows easy
              	re-execution of blocks of code by slicing it (inspired by Janko's
              	comment on 'macros').
              	* Small fixes and doc updates.
              	* Rewrote @history function (was @h). Renamed it to @hist, @h is
              	much too fragile with automagic. Handles properly multi-line
              	statements and takes parameters.
 -11-30  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.18 released.
              	* Fixed nasty namespace bug in initial module imports.
              	* Added copyright/license notes to all code files (except
              	DPyGetOpt). For the time being, LGPL. That could change.
              	* Rewrote a much nicer README, updated INSTALL, cleaned up
              	ipythonrc-* samples.
              	* Overall code/documentation cleanup. Basically ready for
              	release. Only remaining thing: licence decision (LGPL?).
              	* Converted load_config to a class, ConfigLoader. Now recursion
              	control is better organized. Doesn't include the same file twice.
 -11-29  Fernando Perez  <fperez@colorado.edu>
              	* Got input history working. Changed output history variables from
              	_p to _o so that _i is for input and _o for output. Just cleaner
              	convention.
              	* Implemented parametric aliases. This pretty much allows the
              	alias system to offer full-blown shell convenience, I think.
              	* Version 0.1.17 released, 0.1.18 opened.
              	* dot_ipython/ipythonrc (alias): added documentation.
              	(xcolor): Fixed small bug (xcolors -> xcolor)
              	* Changed the alias system. Now alias is a magic command to define
              	aliases just like the shell. Rationale: the builtin magics should
              	be there for things deeply connected to IPython's
              	architecture. And this is a much lighter system for what I think
              	is the really important feature: allowing users to define quickly
              	magics that will do shell things for them, so they can customize
              	IPython easily to match their work habits. If someone is really
              	desperate to have another name for a builtin alias, they can
              	always use __IP.magic_newname = __IP.magic_oldname. Hackish but
              	works.
 -11-28  Fernando Perez  <fperez@colorado.edu>
              	* Changed @file so that it opens the source file at the proper
              	line. Since it uses less, if your EDITOR environment is
              	configured, typing v will immediately open your editor of choice
              	right at the line where the object is defined. Not as quick as
              	having a direct @edit command, but for all intents and purposes it
              	works. And I don't have to worry about writing @edit to deal with
              	all the editors, less does that.
              	* Version 0.1.16 released, 0.1.17 opened.
              	* Fixed some nasty bugs in the page/page_dumb combo that could
              	crash IPython.
 -11-27  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.15 released, 0.1.16 opened.
              	* Finally got ? and ?? to work for undefined things: now it's
              	possible to type {}.get? and get information about the get method
              	of dicts, or os.path? even if only os is defined (so technically
              	os.path isn't). Works at any level. For example, after import os,
              	os?, os.path?, os.path.abspath? all work. This is great, took some
              	work in _ofind.
              	* Fixed more bugs with logging. The sanest way to do it was to add
              	to @log a 'mode' parameter. Killed two in one shot (this mode
              	option was a request of Janko's). I think it's finally clean
              	(famous last words).
              	* Added a page_dumb() pager which does a decent job of paging on
              	screen, if better things (like less) aren't available. One less
              	unix dependency (someday maybe somebody will port this to
              	windows).
              	* Fixed problem in magic_log: would lock of logging out if log
              	creation failed (because it would still think it had succeeded).
              	* Improved the page() function using curses to auto-detect screen
              	size. Now it can make a much better decision on whether to print
              	or page a string. Option screen_length was modified: a value 0
              	means auto-detect, and that's the default now.
              	* Version 0.1.14 released, 0.1.15 opened. I think this is ready to
              	go out. I'll test it for a few days, then talk to Janko about
              	licences and announce it.
              	* Fixed the length of the auto-generated ---> prompt which appears
              	for auto-parens and auto-quotes. Getting this right isn't trivial,
              	with all the color escapes, different prompt types and optional
              	separators. But it seems to be working in all the combinations.
 -11-26  Fernando Perez  <fperez@colorado.edu>
              	* Wrote a regexp filter to get option types from the option names
              	string. This eliminates the need to manually keep two duplicate
              	lists.
              	* Removed the unneeded check_option_names. Now options are handled
              	in a much saner manner and it's easy to visually check that things
              	are ok.
              	* Updated version numbers on all files I modified to carry a
              	notice so Janko and Nathan have clear version markers.
              	* Updated docstring for ultraTB with my changes. I should send
              	this to Nathan.
              	* Lots of small fixes. Ran everything through pychecker again.
              	* Made loading of deep_reload an cmd line option. If it's not too
              	kosher, now people can just disable it. With -nodeep_reload it's
              	still available as dreload(), it just won't overwrite reload().
              	* Moved many options to the no| form (-opt and -noopt
              	accepted). Cleaner.
              	* Changed magic_log so that if called with no parameters, it uses
              	'rotate' mode. That way auto-generated logs aren't automatically
              	over-written. For normal logs, now a backup is made if it exists
              	(only 1 level of backups). A new 'backup' mode was added to the
              	Logger class to support this. This was a request by Janko.
              	* Added @logoff/@logon to stop/restart an active log.
              	* Fixed a lot of bugs in log saving/replay. It was pretty
              	broken. Now special lines (!@,/) appear properly in the command
              	history after a log replay.
              	* Tried and failed to implement full session saving via pickle. My
              	idea was to pickle __main__.__dict__, but modules can't be
              	pickled. This would be a better alternative to replaying logs, but
              	seems quite tricky to get to work. Changed -session to be called
              	-logplay, which more accurately reflects what it does. And if we
              	ever get real session saving working, -session is now available.
              	* Implemented color schemes for prompts also. As for tracebacks,
              	currently only NoColor and Linux are supported. But now the
              	infrastructure is in place, based on a generic ColorScheme
              	class. So writing and activating new schemes both for the prompts
              	and the tracebacks should be straightforward.
              	* Version 0.1.13 released, 0.1.14 opened.
              	* Changed handling of options for output cache. Now counter is
              	hardwired starting at 1 and one specifies the maximum number of
              	entries *in the outcache* (not the max prompt counter). This is
              	much better, since many statements won't increase the cache
              	count. It also eliminated some confusing options, now there's only
              	one: cache_size.
              	* Added 'alias' magic function and magic_alias option in the
              	ipythonrc file. Now the user can easily define whatever names he
              	wants for the magic functions without having to play weird
              	namespace games. This gives IPython a real shell-like feel.
              	* Fixed doc/?/?? for magics. Now all work, in all forms (explicit
              	@ or not).
              	This was one of the last remaining 'visible' bugs (that I know
              	of). I think if I can clean up the session loading so it works
 % I'll release a 0.2.0 version on c.p.l (talk to Janko first
              	about licensing).
 -11-25  Fernando Perez  <fperez@colorado.edu>
              	* Rewrote somewhat oinfo (?/??). Nicer, now uses page() and
              	there's a cleaner distinction between what ? and ?? show.
              	* Added screen_length option. Now the user can define his own
              	screen size for page() operations.
              	* Implemented magic shell-like functions with automatic code
              	generation. Now adding another function is just a matter of adding
              	an entry to a dict, and the function is dynamically generated at
              	run-time. Python has some really cool features!
              	* Renamed many options to cleanup conventions a little. Now all
              	are lowercase, and only underscores where needed. Also in the code
              	option name tables are clearer.
              	* Changed prompts a little. Now input is 'In [n]:' instead of
              	'In[n]:='. This allows it the numbers to be aligned with the
              	Out[n] numbers, and removes usage of ':=' which doesn't exist in
              	Python (it was a Mathematica thing). The '...' continuation prompt
              	was also changed a little to align better.
              	* Fixed bug when flushing output cache. Not all _p<n> variables
              	exist, so their deletion needs to be wrapped in a try:
              	* Figured out how to properly use inspect.formatargspec() (it
              	requires the args preceded by *). So I removed all the code from
              	_get_pdef in Magic, which was just replicating that.
              	* Added test to prefilter to allow redefining magic function names
              	as variables. This is ok, since the @ form is always available,
              	but whe should allow the user to define a variable called 'ls' if
              	he needs it.
              	* Moved the ToDo information from README into a separate ToDo.
              	* General code cleanup and small bugfixes. I think it's close to a
              	state where it can be released, obviously with a big 'beta'
              	warning on it.
              	* Got the magic function split to work. Now all magics are defined
              	in a separate class. It just organizes things a bit, and now
              	Xemacs behaves nicer (it was choking on InteractiveShell b/c it
              	was too long).
              	* Changed @clear to @reset to avoid potential confusions with
              	the shell command clear. Also renamed @cl to @clear, which does
              	exactly what people expect it to from their shell experience.
              	Added a check to the @reset command (since it's so
              	destructive, it's probably a good idea to ask for confirmation).
              	But now reset only works for full namespace resetting. Since the
              	del keyword is already there for deleting a few specific
              	variables, I don't see the point of having a redundant magic
              	function for the same task.
 -11-24  Fernando Perez  <fperez@colorado.edu>
              	* Updated the builtin docs (esp. the ? ones).
              	* Ran all the code through pychecker. Not terribly impressed with
              	it: lots of spurious warnings and didn't really find anything of
              	substance (just a few modules being imported and not used).
              	* Implemented the new ultraTB functionality into IPython. New
              	option: xcolors. This chooses color scheme. xmode now only selects
              	between Plain and Verbose. Better orthogonality.
              	* Large rewrite of ultraTB. Much cleaner now, with a separation of
              	mode and color scheme for the exception handlers. Now it's
              	possible to have the verbose traceback with no coloring.
 -11-23  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.12 released, 0.1.13 opened.
              	* Removed option to set auto-quote and auto-paren escapes by
              	user. The chances of breaking valid syntax are just too high. If
              	someone *really* wants, they can always dig into the code.
              	* Made prompt separators configurable.
 -11-22  Fernando Perez  <fperez@colorado.edu>
              	* Small bugfixes in many places.
              	* Removed the MyCompleter class from ipplib. It seemed redundant
              	with the C-p,C-n history search functionality. Less code to
              	maintain.
              	* Moved all the original ipython.py code into ipythonlib.py. Right
              	now it's just one big dump into a function called make_IPython, so
              	no real modularity has been gained. But at least it makes the
              	wrapper script tiny, and since ipythonlib is a module, it gets
              	compiled and startup is much faster.
              	This is a reasobably 'deep' change, so we should test it for a
              	while without messing too much more with the code.
 -11-21  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.11 released, 0.1.12 opened for further work.
              	* Removed dependency on Itpl. It was only needed in one place. It
              	would be nice if this became part of python, though. It makes life
              	*a lot* easier in some cases.
              	* Simplified the prefilter code a bit. Now all handlers are
              	expected to explicitly return a value (at least a blank string).
              	* Heavy edits in ipplib. Removed the help system altogether. Now
              	obj?/?? is used for inspecting objects, a magic @doc prints
              	docstrings, and full-blown Python help is accessed via the 'help'
              	keyword. This cleans up a lot of code (less to maintain) and does
              	the job. Since 'help' is now a standard Python component, might as
              	well use it and remove duplicate functionality.
              	Also removed the option to use ipplib as a standalone program. By
              	now it's too dependent on other parts of IPython to function alone.
              	* Fixed bug in genutils.pager. It would crash if the pager was
              	exited immediately after opening (broken pipe).
              	* Trimmed down the VerboseTB reporting a little. The header is
              	much shorter now and the repeated exception arguments at the end
              	have been removed. For interactive use the old header seemed a bit
              	excessive.
              	* Fixed small bug in output of @whos for variables with multi-word
              	types (only first word was displayed).
 -11-17  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.10 released, 0.1.11 opened for further work.
              	* Modified dirs and friends. dirs now *returns* the stack (not
              	prints), so one can manipulate it as a variable. Convenient to
              	travel along many directories.
              	* Fixed bug in magic_pdef: would only work with functions with
              	arguments with default values.
 -11-14  Fernando Perez  <fperez@colorado.edu>
              	* Added the PhysicsInput stuff to dot_ipython so it ships as an
              	example with IPython. Various other minor fixes and cleanups.
              	* Version 0.1.9 released, 0.1.10 opened for further work.
              	* Added sys.path to the list of directories searched in the
              	execfile= option. It used to be the current directory and the
              	user's IPYTHONDIR only.
 -11-13  Fernando Perez  <fperez@colorado.edu>
              	* Reinstated the raw_input/prefilter separation that Janko had
              	initially. This gives a more convenient setup for extending the
              	pre-processor from the outside: raw_input always gets a string,
              	and prefilter has to process it. We can then redefine prefilter
              	from the outside and implement extensions for special
              	purposes.
              	Today I got one for inputting PhysicalQuantity objects
              	(from Scientific) without needing any function calls at
              	all. Extremely convenient, and it's all done as a user-level
              	extension (no IPython code was touched). Now instead of:
              		a = PhysicalQuantity(4.2,'m/s**2')
              	one can simply say
              		a = 4.2 m/s**2
              	or even
              		a = 4.2 m/s^2
              	I use this, but it's also a proof of concept: IPython really is
              	fully user-extensible, even at the level of the parsing of the
              	command line. It's not trivial, but it's perfectly doable.
              	* Added 'add_flip' method to inclusion conflict resolver. Fixes
              	the problem of modules being loaded in the inverse order in which
              	they were defined in
              	* Version 0.1.8 released, 0.1.9 opened for further work.
              	* Added magics pdef, source and file. They respectively show the
              	definition line ('prototype' in C), source code and full python
              	file for any callable object. The object inspector oinfo uses
              	these to show the same information.
              	* Version 0.1.7 released, 0.1.8 opened for further work.
              	* Separated all the magic functions into a class called Magic. The
              	InteractiveShell class was becoming too big for Xemacs to handle
              	(de-indenting a line would lock it up for 10 seconds while it
              	backtracked on the whole class!)
              	FIXME: didn't work. It can be done, but right now namespaces are
              	all messed up. Do it later (reverted it for now, so at least
              	everything works as before).
              	* Got the object introspection system (magic_oinfo) working! I
              	think this is pretty much ready for release to Janko, so he can
              	test it for a while and then announce it. Pretty much 100% of what
              	I wanted for the 'phase 1' release is ready. Happy, tired.
 -11-12  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.6 released, 0.1.7 opened for further work.
              	* Fixed bug in printing: it used to test for truth before
              	printing, so 0 wouldn't print. Now checks for None.
              	* Fixed bug where auto-execs increase the prompt counter by 2 (b/c
              	they have to call len(str(sys.ps1)) ). But the fix is ugly, it
              	reaches by hand into the outputcache. Think of a better way to do
              	this later.
              	* Various small fixes thanks to Nathan's comments.
              	* Changed magic_pprint to magic_Pprint. This way it doesn't
              	collide with pprint() and the name is consistent with the command
              	line option.
              	* Changed prompt counter behavior to be fully like
              	Mathematica's. That is, even input that doesn't return a result
              	raises the prompt counter. The old behavior was kind of confusing
              	(getting the same prompt number several times if the operation
              	didn't return a result).
              	* Fixed Nathan's last name in a couple of places (Gray, not Graham).
              	* Fixed -Classic mode (wasn't working anymore).
              	* Added colored prompts using Nathan's new code. Colors are
              	currently hardwired, they can be user-configurable. For
              	developers, they can be chosen in file ipythonlib.py, at the
              	beginning of the CachedOutput class def.
 -11-11  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.5 released, 0.1.6 opened for further work.
              	* Changed magic_env to *return* the environment as a dict (not to
              	print it). This way it prints, but it can also be processed.
              	* Added Verbose exception reporting to interactive
              	exceptions. Very nice, now even 1/0 at the prompt gives a verbose
              	traceback. Had to make some changes to the ultraTB file. This is
              	probably the last 'big' thing in my mental todo list.  This ties
              	in with the next entry:
              	* Changed -Xi and -Xf to a single -xmode option. Now all the user
              	has to specify is Plain, Color or Verbose for all exception
              	handling.
              	* Removed ShellServices option. All this can really be done via
              	the magic system. It's easier to extend, cleaner and has automatic
              	namespace protection and documentation.
 -11-09  Fernando Perez  <fperez@colorado.edu>
              	* Fixed bug in output cache flushing (missing parameter to
              	__init__). Other small bugs fixed (found using pychecker).
              	* Version 0.1.4 opened for bugfixing.
 -11-07  Fernando Perez  <fperez@colorado.edu>
              	* Version 0.1.3 released, mainly because of the raw_input bug.
              	* Fixed NASTY bug in raw_input: input line wasn't properly parsed
              	and when testing for whether things were callable, a call could
              	actually be made to certain functions. They would get called again
              	once 'really' executed, with a resulting double call. A disaster
              	in many cases (list.reverse() would never work!).
              	* Removed prefilter() function, moved its code to raw_input (which
              	after all was just a near-empty caller for prefilter). This saves
              	a function call on every prompt, and simplifies the class a tiny bit.
              	* Fix _ip to __ip name in magic example file.
              	* Changed 'tar -x -f' to 'tar xvf' in auto-installer. This should
              	work with non-gnu versions of tar.

              	* Version 0.1.2. Just to keep track of the recent changes.
              	* Fixed nasty bug in output prompt routine. It used to check 'if
              	arg != None...'. Problem is, this fails if arg implements a
              	special comparison (__cmp__) which disallows comparing to
              	None. Found it when trying to use the PhysicalQuantity module from
              	ScientificPython.
 -11-05  Fernando Perez  <fperez@colorado.edu>
              	* Also added dirs. Now the pushd/popd/dirs family functions
              	basically like the shell, with the added convenience of going home
              	when called with no args.
              	* pushd/popd slightly modified to mimic shell behavior more
              	closely.
              	* Added env,pushd,popd from ShellServices as magic functions. I
              	think the cleanest will be to port all desired functions from
              	ShellServices as magics and remove ShellServices altogether. This
              	will provide a single, clean way of adding functionality
              	(shell-type or otherwise) to IP.
 -11-04  Fernando Perez  <fperez@colorado.edu>
              	* Added .ipython/ directory to sys.path. This way users can keep
              	customizations there and access them via import.
 -11-03  Fernando Perez  <fperez@colorado.edu>
              	* Opened version 0.1.1 for new changes.
              	* Changed version number to 0.1.0: first 'public' release, sent to
              	Nathan and Janko.
              	* Lots of small fixes and tweaks.
              	* Minor changes to whos format. Now strings are shown, snipped if
              	too long.
              	* Changed ShellServices to work on __main__ so they show up in @who
              	* Help also works with ? at the end of a line:
              		?sin and sin?
              	both produce the same effect. This is nice, as often I use the
              	tab-complete to find the name of a method, but I used to then have
              	to go to the beginning of the line to put a ? if I wanted more
              	info. Now I can just add the ? and hit return. Convenient.
 -11-02  Fernando Perez  <fperez@colorado.edu>
              	* Python version check (>=2.1) added.
              	* Added LazyPython documentation. At this point the docs are quite
              	a mess. A cleanup is in order.
              	* Auto-installer created. For some bizarre reason, the zipfiles
              	module isn't working on my system. So I made a tar version
              	(hopefully the command line options in various systems won't kill
              	me).
              	* Fixes to Struct in genutils. Now all dictionary-like methods are
              	protected (reasonably).
              	* Added pager function to genutils and changed ? to print usage
              	note through it (it was too long).
              	* Added the LazyPython functionality. Works great! I changed the
              	auto-quote escape to ';', it's on home row and next to '. But
              	both auto-quote and auto-paren (still /) escapes are command-line
              	parameters.
 -11-01  Fernando Perez  <fperez@colorado.edu>
              	* Version changed to 0.0.7. Fairly large change: configuration now
              	is all stored in a directory, by default .ipython. There, all
              	config files have normal looking names (not .names)
              	* Version 0.0.6 Released first to Lucas and Archie as a test
              	run. Since it's the first 'semi-public' release, change version to
              	> 0.0.6 for any changes now.
              	* Stuff I had put in the ipplib.py changelog:
              	Changes to InteractiveShell:
              	- Made the usage message a parameter.
              	- Require the name of the shell variable to be given. It's a bit
              	of a hack, but allows the name 'shell' not to be hardwired in the
              	magic (@) handler, which is problematic b/c it requires
              	polluting the global namespace with 'shell'. This in turn is
              	fragile: if a user redefines a variable called shell, things
              	break.
              	- magic @: all functions available through @ need to be defined
              	as magic_<name>, even though they can be called simply as
              	@<name>. This allows the special command @magic to gather
              	information automatically about all existing magic functions,
              	even if they are run-time user extensions, by parsing the shell
              	instance __dict__ looking for special magic_ names.
              	- mainloop: added *two* local namespace parameters. This allows
              	the class to differentiate between parameters which were there
              	before and after command line initialization was processed. This
              	way, later @who can show things loaded at startup by the
              	user. This trick was necessary to make session saving/reloading
              	really work: ideally after saving/exiting/reloading a session,
              	*everything* should look the same, including the output of @who. I
              	was only able to make this work with this double namespace
              	trick.
              	- added a header to the logfile which allows (almost) full
              	session restoring.
              	- prepend lines beginning with @ or !, with a and log
              	them. Why?  !lines: may be useful to know what you did @lines:
              	they may affect session state. So when restoring a session, at
              	least inform the user of their presence. I couldn't quite get
              	them to properly re-execute, but at least the user is warned.
              	* Started ChangeLog.
