#
# Revision 1.1.2.1  2000/05/16 02:07:01  RD
#
# Moved and reorganized wxPython directories
#
# Now builds into an intermediate wxPython package directory before
# installing
#
# Revision 1.3  1999/04/30 03:29:53  RD
#
# wxPython 2.0b9, first phase (win32)
# Added gobs of stuff, see wxPython/README.txt for details
#
# Revision 1.2.4.1  1999/03/27 23:30:00  RD
#
# wxPython 2.0b8
#     Python thread support
#     various minor additions
#     various minor fixes
#
# Revision 1.2  1998/12/15 20:44:34  RD
# Changed the import semantics from "from wxPython import *" to "from
# wxPython.wx import *"  This is for people who are worried about
# namespace pollution, they can use "from wxPython import wx" and then
# prefix all the wxPython identifiers with "wx."
#
# Added wxTaskbarIcon for wxMSW.
#
# Made the events work for wxGrid.
#
# Added wxConfig.
#
# Added wxMiniFrame for wxGTK, (untested.)
#
# Changed many of the args and return values that were pointers to gdi
# objects to references to reflect changes in the wxWindows API.
#
# Other assorted fixes and additions.
#
# Revision 1.1  1998/08/09 08:28:05  RD
