// This SWIG library file supports C arrays of various datatypes.
// These arrays are probably *not* compatible with scripting languages
// but they are compatible with C functions.

/* Revision History
 * -- $Log$
 * -- Revision 1.1  2002/04/29 19:56:49  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.
