  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
  42 direct access.
