Today there are two more CVS repositories:
"bml" -- for BML files
"wcmtools" -- for tools and libraries that other sites could use.
The only thing in wcmtools right now is multicvs.pl, which is a re-write of cvsreport.pl and reads a config file (livejournal's is in livejournal::cvs/multicvs.conf) and knows how to deal with many CVS repositories, not just 1 or 2.
cvsreport.pl still exists, but now is just a couple line wrapper around multicvs.pl.
You'll want to keep using cvsreport.pl probably, since typing --conf=$LJHOME/cvs/multicvs.pl all the time will get annoying.
Instructions for getting the new CVS repositories can be found here:
A lot more stuff will be moving into wcmtools ... the database connection/admin code, user priv/cap framework, etc, etc, etc. Anything that could possibly be utilized by another website will most likely be moving.
And it's all being removed from livejournal CVS, so you gotta do the above-linked couple steps, otherwise your installation won't run.
