There are three primary development sites for the gpc package. In order of appearance:
gmc's place in Den Haag ( ), which will have its graphical (on-the-fly generated) presentation on the gpc homepage.

Some old and big building aloha calls home, which will be online eventually. Maybe his old homepage is still there on

The third site is in almelo (, who will undoubtly have his homepage too (since he is the one working on the web-development).
