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. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@15307 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

|
* 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.

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