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