C. Reference manual for Administrative files
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 The administrative files.
The most important of these files is the `modules'
file, which defines the modules inside the repository.
