Added XML simplification scripts for generating the wxPython metadata xml.

1 # 11/6/2003 - Jeff Grimmett (grimmtooth@softhome.net)
2 #
3 # o Updated for wx namespace
4 # o Also corrected minor bug where 'true' was being used instead of 'True'.
5 # Doesn't fail for * import (I guess that is still defined in wx), but does
6 # in the manner we're importing wx now.
