/*! \page af_overview Application Framework
The 'af' directory contains all source code for the cross-platform
application framework. This directory contains the following
subdirectories:
- Directory ev
- Source code for the event mechanism for the cross-platform application
framework. This code contains the machinery to do key bindings,
mouse bindings, menu bars, and tool bars. This code is
currently used by the word processor, but we expect to also use
it for the spreadsheet application.
- Directory gr
- Source code for graphics (drawing code, font code, etc.)
- Directory util
- Source code for general-purpose utility functions.
- Directory xap
- Source code for application-neutral portion of the
cross-platform framework defined in ev.
FIXME: Need more overviews in sub directories...
