easy follow the magic vendor branch 1.1.1.x, T10 is probably the tag that
represents the most recent vendor-branch import.
now the 'T2 (revision: 220.127.116.11)' and 'T2 (revision: 18.104.22.168)' looks
funny, did not think you could apply the same tag to two revisions, but the
last import in which the file _changed_ was T2 (revision: 22.214.171.124). A file
with a richer import & change history would have made this exercise more fun.
OK, wait a second...I see why you chose this file...I can not be SURE that the
tag was applied during an import, I only assumed it was because it followed the
form of the ones used for import, and I believe than any sane (or one who
wanted to stay that way) person would use a different form of tag for their own
work than they did for imports. I would need at least one more set of history
to figure it out for sure. You got me.
there are however tools that can help. broken record, Yep that's right I am
about to mention cvs2cl.pl again. (can't help it, I like it :)
and FLUFFY has began to do maintenance and is keeping it on cpan (so far looks
like he has added an ignore_tags mod)
If you run 'cvs2cl.pl -r -t -b' in your sandbox and look for the tags, found
with above cvs status, you will find to which files (and when iff at least one
file changed) a tag was applied. and if all the files tagged at that time have
the import 'magic' revision scheme, the tag is most likely an import one. Now I
know why I have a file that gets updated and tagged by the script I hand apply
tags with, it keeps me sanER, I know which are mine and which are vendor/other
branch stuff seems a little tougher and as I don't have other than the vendor
branch to check I can't test to give you any pointers (other than figure out
what the ''magic'' revision stamp looks like).
It might be posible to use the XML output to have a machine parse it out.
I'd crawl over an acre of 'Visual This++' and 'Integrated Development
That' to get to gcc, Emacs, and gdb. Thank you.
