| 10 | * $Log$ | |
| 11 | * Revision 1.1 2002/04/29 19:56:49 RD | |
| 12 | * Since I have made several changes to SWIG over the years to accomodate | |
| 13 | * special cases and other things in wxPython, and since I plan on making | |
| 14 | * several more, I've decided to put the SWIG sources in wxPython's CVS | |
| 15 | * instead of relying on maintaining patches. This effectivly becomes a | |
| 16 | * fork of an obsolete version of SWIG, :-( but since SWIG 1.3 still | |
| 17 | * doesn't have some things I rely on in 1.1, not to mention that my | |
| 18 | * custom patches would all have to be redone, I felt that this is the | |
| 19 | * easier road to take. | |

| 39 | This module provides access to the C math library and contains most | |
| 40 | of the functions in <math.h>. Most scripting languages already provide | |
| 41 | math support, but in certain cases, this module can provide more | |
