Added Jason Orendorff's "Path" module, http://www.jorendorff.com/

IPython/path.py

+""" path.py - An object representing a path to a file or directory.
+
+Example:
+
+from path import path
+d = path('/home/guido/bin')
+for f in d.files('*.py'):

+This module requires Python 2.2 or later.

+# TODO
+#   - Bug in write_text().  It doesn't support Universal newline mode.
+#   - Better error message in listdir() when self isn't a
+#     directory. (On Windows, the error message really sucks.)
+#   - Make sure everything has a good docstring.
+#   - Add methods for regex find and replace.
+#   - guess_content_type() method?
+#   - Perhaps support arguments to touch().
+#   - Could add split() and join() methods that generate warnings.
+#   - Note:  __add__() technically has a bug, I think, where
+#     it doesn't play nice with other types that implement
+#     __radd__().  Test this.

+            string.
+
+          - linesep - keyword argument - str/unicode - The sequence of
+            characters to be used to mark end-of-line.  The default is
+            os.linesep.  You can also specify None; this means to
+            leave all newlines as they are in 'text'.
+
+          - append - keyword argument - bool - Specifies what to do if
+            the file already exists (True: append to the end of it;
+            False: overwrite it.)  The default is False.
+
+
+        --- Newline handling.
+
+        write_text() converts all standard end-of-line sequences
+        ('\n', '\r', and '\r\n') to your platform's default end-of-line
+        sequence (see os.linesep; on Windows, for example, the
+        end-of-line marker is '\r\n').
+
+        If you don't like your platform's default, you can override it
+        using the 'linesep=' keyword argument.  If you specifically want
+        write_text() to preserve the newlines as-is, use 'linesep=None'.
+
+        This applies to Unicode text the same as to 8-bit text, except
+        there are three additional standard Unicode end-of-line sequences:
+        u'\x85', u'\r\x85', and u'\u2028'.
+
+        (This is slightly different from when you open a file for
+        writing with fopen(filename, "w") in C or file(filename, 'w')
+        in Python.)
+
+
+        --- Unicode
+
+        If 'text' isn't Unicode, then apart from newline handling, the

 IPython -- An enhanced Interactive Python
 
 One of Python's nicest features is its interactive interpreter. This allows
 very fast testing of ideas without the overhead of creating test files as is
 typical in most programming languages. However, the interpreter supplied with
 the standard Python distribution is fairly primitive (and IDLE isn't really
 much better).
 
 IPython tries to:
 
   i - provide an efficient environment for interactive work in Python
   programming. It tries to address what we see as shortcomings of the standard
   Python prompt, and adds many features to make interactive work much more
   efficient.
 
   ii - offer a flexible framework so that it can be used as the base
   environment for other projects and problems where Python can be the
   underlying language. Specifically scientific environments like Mathematica,
   IDL and Mathcad inspired its design, but similar ideas can be useful in many
   fields. Python is a fabulous language for implementing this kind of system
   (due to its dynamic and introspective features), and with suitable libraries
   entire systems could be built leveraging Python's power.
 
   iii - serve as an embeddable, ready to go interpreter for your own programs.
 
 IPython requires Python 2.2 or newer.
