 Refactoring the main IPython core
 ---------------------------------
 
+During the summer of 2009, we began refactoring IPython's core.  The main
+thrust in this work was make the IPython core into a set of loosely coupled
+components.  The base component class for this is 
+:class:`IPython.core.component.Component`.  This section outlines the status
+of this work.
+
+Parts of the IPython core that have been turned into components:
+
+* The main :class:`InteractiveShell` class.
+* The aliases (:mod:`IPython.core.aliases`).
+* The display and builtin traps (:mod:`IPython.core.display_trap` and
+  :mod:`IPython.core.builtin_trap`).
+* The prefilter machinery (:mod:`IPython.core.prefilter`).
+
+Parts of the IPythoncore that need to be turned into components:
+
+* Magics.
+* Input and output history management.
+* Prompts.
+* Completers.
+* Logging.
+* Exception handling.
+* Anything else.

 Performance problems

 * The controller stores a large amount of state in Python dictionaries. Under
   heavy usage, these dicts with get very large, causing memory usage problems.
-  We need to develop more scalable solutions to this problem, such as using a
-  sqlite database to store this state. This will also help the controller to
