Head only file

[Kent Henneuse]

I have done some digging in the mail archives but the search I am doing
is
not an easy one do to the word choice.

What I would like to be able to do is create a file in cvs that can only
live
in the HEAD.  If a branch is created the file stays in HEAD but some
sort of
reference exists so that when editing the file in branch you are really 
modifying the HEAD version.  If done by hand it my be like this:

   cvs checkout -r ReleaseA
   cvs update -A SpecialFile

One use for this is in creating a file that maintains a unique number
for
logging messages in a product to be attached to.  If you create a new
log
message in a release you don't want to use the same number in a
different
context in the next release.

        Thanks,
