Yeah, it's a little ill-defined.  Loosely speaking, a module is any
part of the tree under $CVSROOT that can be checked out as a unit.
For example, immediately after you do your "cvs init" there is a
$CVSROOT/CVSROOT subdirectory with cvs administrative files,
and you can check it its contents like so:

    cd some/place/clean
    cvs checkout CVSROOT

In that sense, CVSROOT is a module.  After you import a few trees,
every top-level directory under $CVSROOT is a module because you can
check it out by name.

In that same CVSROOT administrative sandbox, you will find a "modules"
file.  You can edit that file to make other subtrees of your repository
accessible by name, like the top-level subtrees.  An entry like this,

    scripts-A   projectA/lib/tools/subtools/scripts

makes a deep subdirectory available through

    cvs checkout scripts-A

So there is a somewhat more precise definition:  a module is anything
that has an entry in $CVSROOT/CVSROOT/modules .
