Looking for *real* docs

[Chris]

Howdy,

I'm trying to write some code to allow you to browse a repository. Crucial 
to this is thorough documentation of how to query the repository for name & 
message information (through using 'log', I guess), as well as 
documentation for the output of such commands, so I can parse it. I've read 
man pages for rcs, rlog, and cvs, along with additional online material 
including the Perdeqvist (sp) thingee, and I can't find anything, or even a 
reference to what I'm looking for.

There are several add-on tools that do this, and I could plow through their 
source if need be, but I'd rather not - I'd rather read what the 
tool-makers read, whatever that is.

Any ideas?
Chris
