The 'src' directory contains all source code for all modules and applications
in the tree.  This directory contains the following subdirectories:

other
	This is where source code for all third-party libraries is placed.
	For example, we use James Clark's XML parser, expat, which is
	stored here.  In general, don't put libraries in 'other' if
	we are making substantial modifications to the code.  Minor bug
	fixes are fine (please send the fix back to the original author).
	Customizations to make the library fit into our build system are
	fine.  Source code in 'other' is not required to comply with
	every one of our coding guidelines.  Don't make gratuitous sweeping
	changes just to fix the indent level on someone else's library.

doc
	Source code for the word processor application.

util
	Source code for general-purpose utility functions.

Subdirectories below this one may have additional hierarchy to further break
things down by module.  However, eventually, source code should find itself
in a directory which indicates the portability of the code within it.  For
example, cross-platform code should always be placed in a subdirectory called
'xp'.  Win32-specific code should be in a subdirectory called 'win32'.
