RE: Question re: deleted tags

[Rick Genter]

I believe that the "real" tags repository, as you call it, is knowledge
scattered in each ,v file in the repository. Each file lists the tags
with which it is tagged. That's why when you specify a tag that is not
in the val-tags file it can take a long time to process the command; CVS
has to look at every ,v file in the module(s) referenced in the command
to see if the tag exists.

I understand WHY now. Since val-tags is just a cache,
where is the "real" tags repository. Again in my last
post, I said I did NOT see the deleted tag in val-tags
anymore, and don't see a tag that should still be there.
