===========================
IPython module organization
===========================

As of the 0.11 release of IPython, the top-level packages and modules have
been completely reorganized.  This section describes the purpose of the
top-level IPython subpackages.

Subpackage descriptions
=======================

* :mod:`IPython.config`.  This package contains the configuration system of 
  IPython, as well as default configuration files for the different IPython
  applications.

* :mod:`IPython.core`. This sub-package contains the core of the IPython
  interpreter, but none of its extended capabilities.

* :mod:`IPython.deathrow`. This is for code that is outdated, untested,
  rotting, or that belongs in a separate third party project. 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 third-party Python package. No new code will
  be allowed here.

* :mod:`IPython.extensions`.  This package contains fully supported IPython
  extensions.  These extensions adhere to the official IPython extension API
  and can be enabled by adding them to a field in the configuration file.

* :mod:`IPython.external`. This package contains third party packages and
  modules that IPython ships internally to reduce the number of dependencies.
  Usually, these are short, single file modules.

* :mod:`IPython.frontend`. This package contains the various IPython
  frontends. Currently, the code in this subpackage is very experimental and
  may be broken.

* :mod:`IPython.gui`.  Another semi-experimental wxPython based IPython GUI.

* :mod:`IPython.kernel`.  This contains IPython's parallel computing system.

* :mod:`IPython.lib`. IPython has many extended capabilities that are not part
  of the IPython core. These things will go here and in.  Modules in this
  package are similar to extensions, but don't adhere to the official
  IPython extension API.

* :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 approval of the core IPython developers, tests and
  documentation.

* :mod:`IPython.scripts`.  This package contains a variety of top-level
  command line scripts.  Eventually, these should be moved to the 
  :file:`scripts` subdirectory of the appropriate IPython subpackage.

* :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 and that don't
  depend on things in the rest of IPython.
