8/12    Say I have some directories in a CVS tree containing source for
        related libraries. Some of these libraries have dependencies on
        other libraries. If I want to be able to retrieve a particular
        version of a library, along with the correct versions of the other
        libraries it's dependent on, how should I organize things? I was
        thinking of tagging the library and its dependencies with the
        same tag, like libfoo-1-1-0 or something, and then doing a
        cvs update -f -r libfoo-1-1-0, but this has some drawbacks. Does
        anyone know of better methods? Thanks.
        \_ What drawbacks?  This would be the correct method.  tag the group
           or trees (with the desired versions) under an umbrella tag.
