* swig_lib/python/python.cfg
*
- * This file contains coded needed to add variable linking to the
- * Python interpreter. C variables are added as a new kind of Python
- * datatype.
- *
- * Also contains supporting code for building python under Windows
- * and things like that.
- *
- * $Log$
- * Revision 1.1 1999/08/04 05:25:58 RD
- * New Makefile/Setup files supporting multiple dynamic extension modules
- * for unix systems.
- *
- * Fixes for the wxGLCanvas demo to work around a strange bug in gtk.
- *
- * SWIG support routines now compiled separately instead of being bundled
- * in wx.cpp.
- *
+ * Contains variable linking and pointer type-checking code.
