9 * Since I have made several changes to SWIG over the years to accomodate
10 * special cases and other things in wxPython, and since I plan on making
11 * several more, I've decided to put the SWIG sources in wxPython's CVS
12 * instead of relying on maintaining patches. This effectivly becomes a
13 * fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still
14 * doesn't have some things I rely on in 1.1, not to mention that my
15 * custom patches would all have to be redone, I felt that this is the
16 * easier road to take.
