Adapt your tree structure.  Do *not* mix files from teams A and B in a
single directory, CVS won't handle that well.

The modules file can package things nicely for you, if you can live
with the resulting sandbox structure.

    _utils      -d utils path/to/utilities
    _team_A     -d A path/to/team/A/files
    _team_B     -d B path/to/team/B/files

These aren't meant to be checked out.  If you did check out module
"_team_A", you would get team A's tree under a top-level directory
called "A" (from the -d option).  It wouldn't do you any good because
the shared utilities aren't there.

Next, create wrapper modules for each team.

    Team_A      &_team_A &_utils
    Team_B      &_team_B &_utils

If you check out "Team_A", you'll get a tree like this:

    Team_A/
        utils/
            (the shared utilities tree)
        A/
            (team A's subtree)

and similarly for "Team_B".  These are complete trees, useable by the
teams, if they can stomach the layout.  Lean on them.

You'll also need to check out the joint project, so create a module
for that:

    Full        path/to/glue &_team_A &team_B &_utils

A checked-out sandbox would look like this:

    Full/
        (glue files)
        utils/
            (the shared utilities)
        A/
            (team A's subtree)
        B/
            (team B's subtree)

The "glue files" could include a top-level Makefile that knows what to
do with the subtrees, plus a README or two.  It could even be a big
sutbree in its own right.  Put in whatever you need to integrate the
two subprojects.
