GPuTTY is not directly derived from the DeforaOS project. but it eventually found its way here. The attempt at removing obsolete code per Gtk+ 2.0 was trickier (and more boring) than expected, but it is now done in a way that seems to finally work.
The current source code in CVS can be considered final for the 0.9.9 release, and I will wrap it up some time soon in ways more suitable for distribution.
