Usage:  build_renamers.py destdir modulename filename.xml
 | 
						|
 | 
						|
Scans the XML file produced by SWIG (see setup.py) and generate the
 | 
						|
%rename directives needed to implement the new wx namespace.  The
 | 
						|
rename directives are output in a file named _modulename_rename.i in
 | 
						|
the destdir given.
 | 
						|
 | 
						|
Also output a reverse 'renamer' Python module located in
 | 
						|
wxPython/filename.py (relative the the current dir) to make a
 | 
						|
backwards compatibility interface for the old wxPython packages.
