What you're trying to do has been discussed ad-nauseum in this forum for
years.  The method you prefer to use, though not popular, has been used
successfully in the past with success.

The "cvs tag -d" command does work in combination with wildcards on the
command line, and it also works with -l and with recursion.  Doing a "cvs
log" on a makefile or something like that should produce a list of all of
the tags applied to a common file, which you can use to write a script
to clean them out of your copied RCS files.  Be careful to remove only
version tags.

You'll also want to audit the branch tags, and do "cvs rm" as needed on
each branch to prevent checkouts on branches from giving the wrong
configurations.  (That means most likely checking out on every branch
and doing a "cvs rm" in the new locations of all of the moved files and
