In addition to the Cederqvist, the FAQ, and the other files in the distribution itself, there are Internet resources devoted to CVS. If you're going to administrate a CVS server, you'll probably want to join the info-cvs mailing list. To subscribe, send email to email@example.com (the list itself is firstname.lastname@example.org). Traffic can be medium to heavy, around 10 to 20 emails a day, most of them questions seeking answers. The majority of these can be deleted without reading (unless you want to help people by answering their questions, which is always nice), but every now and then someone will announce the discovery of a bug or announce a patch that implements some feature you've been wanting.
You can also join the formal bug report mailing list, which includes every bug report sent in. This probably isn't necessary, unless you intend to help fix the bugs, which would be great, or you're terrifically paranoid and want to know about every problem other people find with CVS. If you do want to join, send email to email@example.com.
There's also a Usenet newsgroup,
is about version control and configuration management systems in
general, in which there is a fair amount of discussion about CVS.
Finally, there are at least three Web sites devoted to CVS. Cyclic Software's http://www.cyclic.com has been CVS's informal home site for a few years, and probably will continue to be for the foreseeable future. Cyclic Software also provides server space and Net access for the repository where the CVS sources are kept. The Cyclic Web pages contain comprehensive links to experimental patches for CVS, third-party tools that work with CVS, documentation, mailing list archives, and just about everything else. If you can't find what you need in the distribution, http://www.cyclic.com is the place to start looking.
Two other good sites are Pascal Molli's http://www.loria.fr/~molli/cvs-index.html and Sean Dreilinger's http://durak.org/cvswebsites/. The biggest attraction at Molli's site is, of course, the FAQ, but it also has links to CVS-related tools and mailing list archives. Dreilinger's site specializes in information about using CVS to manage Web documents and also has a CVS-specific search engine.
