+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.
