"""
This script will search for installed versions of wxPython on OSX and
allow the user to choose one to uninstall. It then will use the
metadata stored about the installed package to remove all the files
associated with that install.
Only the files installed by the main Installer Package will be
removed. This includes the Python modules and the wxWidgets shared
libraries. If you also installed the demo or docs by dragging them out
of the disk image, then you will need to drag them to the Trash
yourself.
