Since I have made several changes to SWIG over the years to accomodate

Browse Source 
special cases and other things in wxPython, and since I plan on making
several more, I've decided to put the SWIG sources in wxPython's CVS
instead of relying on maintaining patches.  This effectivly becomes a
fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still
doesn't have some things I rely on in 1.1, not to mention that my
custom patches would all have to be redone, I felt that this is the
easier road to take.
