+/* Revision History
+ * $Log$
+ * Revision 1.1  2002/04/29 19:56:49  RD
+ * Since I have made several changes to SWIG over the years to accomodate
+ * 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.
