   8  * Revision 1.1  2002/04/29 19:56:52  RD
   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.
