 158 # wxPython 2.0b9, first phase (win32)
 159 # Added gobs of stuff, see wxPython/README.txt for details

 166 #     various minor fixes
 167 #
 168 # Revision 1.2  1998/12/15 20:44:34  RD
 169 # Changed the import semantics from "from wxPython import *" to "from
 170 # wxPython.wx import *"  This is for people who are worried about
 171 # namespace pollution, they can use "from wxPython import wx" and then
 172 # prefix all the wxPython identifiers with "wx."
 173 #
 174 # Added wxTaskbarIcon for wxMSW.
 175 #
 176 # Made the events work for wxGrid.
 177 #
 178 # Added wxConfig.
 179 #
 180 # Added wxMiniFrame for wxGTK, (untested.)
 181 #
 182 # Changed many of the args and return values that were pointers to gdi
 183 # objects to references to reflect changes in the wxWindows API.
 184 #
 185 # Other assorted fixes and additions.
