User.pm interface to the security mechanisms (access.db) optional vsql support and attribute queries to DB instead of going to the shell better docs many more examples Interface the command execution component to PVCS DTK. Also the config file reader. This will require, of course, more code to execute triggers, etc. I've not heard great things about the stability of the DTK, either. or Short-circuit some of the folder/project operators to avoid calling the tool for each member. Instead, call the tool for all members in the folder/archive. Just doing this may help alot. Possibly do something with PVCSPRIV. I dunno if it's so important.
