| | 11 | * $Log$ |
| | 12 | * Revision 1.1 2002/04/29 19:56:49 RD |
| | 13 | * Since I have made several changes to SWIG over the years to accomodate |
| | 14 | * special cases and other things in wxPython, and since I plan on making |
| | 15 | * several more, I've decided to put the SWIG sources in wxPython's CVS |
| | 16 | * instead of relying on maintaining patches. This effectivly becomes a |
| | 17 | * fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still |
| | 18 | * doesn't have some things I rely on in 1.1, not to mention that my |
| | 19 | * custom patches would all have to be redone, I felt that this is the |
| | 20 | * easier road to take. |
