while I agree with Shankar, that for most situations having the whole
repository tagged is the best method and for your situation I think it is
correct, I have found a use for tagging just some files.
When working with a mess of scripts used for testing a product, I found that I
had several 'engineers debug' scripts which needed controlled and could
eventually be used for THE test, but for each formal test it was decided that
only the scripts called out formally in the test description were to be
available to the testers (this removes the management worry that they are
running the "just make it work backdoor" scripts).
I found that if I had a file with a list of the filenames (one per line) used
in the formal test I could do a variation on the following (in bash):
while [[ "$INPUTLINE" != "EOF" ]]
#the following should tag each file individually so we only tag those we
(cd $BASE_SCRIPTS_DIR/scripts;cvs tag -l $TAGNAME $INPUTLINE)
tagsome < list_of_the_filenames.txt
#the following would retrieve only the files that had the
#tag applied to them.
#I do not know if this is a 'known feature' of cvs, so it
#may change in the future.:)
cvs checkout -r$TAGNAME scripts
Note: how you get list_of_the_filenames.txt is your problem, I had to do
several contortions of `strings ?.doc|grep patterns|awk|perl_script` (Yes you
can program when you are just the CM person :)

I'd crawl over an acre of 'Visual This++' and 'Integrated Development
That' to get to gcc, Emacs, and gdb. Thank you.
