Inside the repository, in the directory `$CVSROOT/CVSROOT', there are a number of supportive files for CVS. You can use CVS in a limited fashion without any of them, but if they are set up properly they can help make life easier. For a discussion of how to edit them, See section 15.0 The administrative files.
The most important of these files is the `modules' file, which defines the modules inside the repository.
