Note: this software was last released about 20 years ago and hasn't been tested in almost that long. Also it's written for an ancient version of Gnome so who knows if it still works. It was pretty useful at the time, though.
There are still a number of features that I want to implement in pgtc, and the distribution could be made nicer by adding autoconf functionality, etc, to it, but that will have to wait for a later version.
The current version is 0.2.0, released on Feb 27, 2000. See the ChangeLog for changes.
