 =============================
 IPython module reorganization
 =============================
 
 Currently, IPython has many top-level modules that serve many different purposes.
 The lack of organization make it very difficult for developers to work on IPython
 and understand its design. This document contains notes about how we will reorganize
 the modules into sub-packages.
 
 .. warning::
 
     This effort will possibly break third party packages that use IPython as
     a library or hack on the IPython internals.
 
 .. warning::
 
     This effort will result in the removal from IPython of certain modules
     that are not used anymore, don't currently work, are unmaintained, etc.
 
 
 Current subpackges
 ==================
 
 IPython currently has the following sub-packages:
 
 * :mod:`IPython.config`
 
 * :mod:`IPython.Extensions`
 
 * :mod:`IPython.external`
 
 * :mod:`IPython.frontend`
 
 * :mod:`IPython.gui`
 
 * :mod:`IPython.kernel`
 
 * :mod:`IPython.testing`
 
 * :mod:`IPython.tests`
 
 * :mod:`IPython.tools`
 
 * :mod:`IPython.UserConfig`
 
 New Subpackages to be created
 =============================
 
 We propose to create the following new sub-packages:
 
 * :mod:`IPython.core`. This sub-package will contain the core of the IPython
   interpreter, but none of its extended capabilities.
 
 * :mod:`IPython.lib`. IPython has many extended capabilities that are not part
   of the IPython core. These things will go here.  Any better names than 
   :mod:`IPython.lib`?
 
 * :mod:`IPython.utils`. This sub-package will contain anything that might
   eventually be found in the Python standard library, like things in
-  :mod:`genutils`. Each sub-module in this sub-package should contain functions 
-  and classes that serve a single purpose.
+  :mod:`genutils`. Each sub-module in this sub-package should contain
+  functions and classes that serve a single purpose.
 
 * :mod:`IPython.deathrow`. This is for code that is untested and/or rotting
   and needs to be removed from IPython. Eventually all this code will either
   i) be revived by someone willing to maintain it with tests and docs and
   re-included into IPython or 2) be removed from IPython proper, but put into
   a separate top-level (not IPython) package that we keep around. No new code
   will be allowed here.
 
 * :mod:`IPython.quarantine`.  This is for code that doesn't meet IPython's 
   standards, but that we plan on keeping.  To be moved out of this sub-package
   a module needs to have a maintainer, tests and documentation.
 
 Where things will be moved
 ==========================
 
 * :file:`ColorANSI.py`.  Move to :file:`IPython/core/coloransi.py`.  Maybe move to
   :mod:`IPython.lib` or :mod:`IPython.python`?

 Other things
 ============
 
 When these files are moved around, a number of other things will happen at the same time:
 
 1. Test files will be created for each module in IPython. Minimally, all
    modules will be imported as a part of the test. This will serve as a 
    test of the module reorganization. These tests will be put into new
    :file:`tests` subdirectories that each package will have.
 
 2. PyFlakes and other code checkers will be run to look for problems.
 
 3. Modules will be renamed to comply with PEP 8 naming conventions:  all
    lowercase and no special characters like ``-`` or ``_``.
 
 4. Existing tests will be moved to the appropriate :file:`tests`
    subdirectories.
