XML documentation

One of my more long-term pet projects is a version of the wxWindows class documentation that is structured in XML rather than the quite loosely tex format.

The code for converting the .tex docs to the classes.xml
A DTD defining the structure of the xml document
The result, classes.xml
(Warning: as XML files go, this is a pretty big one. Some browsers, like mozilla, are known to have problems showing it!)
This can be used to generate a class hierarchy
This can be used to generate a documentation browser
This can be used to generate a list of all (?) events with descriptions
This can be used to generate an overview of what classes support what platforms
This can be used to generate an overview of classes by category back (work in progress)
This can be used to generate docs in DocBook format, which can be used to generate the online docs back again

Also, this is used in the IRC bot 'wxOracle' (thanks Brian Victor! :)) on #wxwindows on irc (freenode):

11:53 < raboof:#wxwidgets> @describe wxMouseEvent::GetPosition
11:53 < wxOracle:#wxwidgets> wxPoint GetPosition ()
11:53 < wxOracle:#wxwidgets> void GetPosition (wxCoord*  x, wxCoord*  y)
11:53 < wxOracle:#wxwidgets> void GetPosition (long*  x, long*  y)
11:53 < wxOracle:#wxwidgets>   Sets *x and *y to the position at which the 
                             event occurred.  Returns the physical mouse 
			     position in pixels.
