It's not the lack of documentation. I don't even know where to start.
Where is the main web page for each of cells, celtk, cello, and cells-gtk? Where are the source code repositories for each? Is there a central location for the tidbits of documentation that exist?
Also, what's the status of each. Actively developed, "finished", or left to rot? KT, which are you working on the most?
Thanks, -Stu P.S. It would be real nice to have a canonical git repository for each on github or gitorious.
