Ok, unfortunately the way open source documentation works often is "Now that
you understand the problem please describe it in the doc for the next person
and submit the doc patch"....
Ok, now that you understand the problem please describe it in the doc for
the next person and submit the doc patch. (on address@hidden) :)
Honestly, I do find that having someone who does not know, but is trying to
understand, the subject matter DRAG (kicking and screaming) it out of
someone who does, makes some of the best documentation. sorry.

Import is a hack, according to some, that essentially does
'for i in `find . -type d`; do cvs add $i;cvs commit $i ;done'
'for i in `find . -type f`; do cvs add $i;cvs commit $i ;done'
in an out of sand box tree. I say "essentially" because there are some other
things going on like it puts the initial version on a 'special' branch
(which causes trouble using it with normal branches, and is why some call it

I believe though that much of your (our) confusion came from your use of RCS
keywords, and there are known problems with them.
perhaps the updating person should link from annotate documentation to
another "problems with keywords" section in 12.
BTW from section 12.2 Using keywords:
"CVS will automatically (Or, more accurately, as part of the update run that
automatically happens after a commit.) expand the string as part of the
Except for users with RCS keywords, the automatic update after commit is
invisible to users. Also IIRC CVS may only do that auto update if the client
found an RCS keyword in the file, but check the code to be sure.

Some time soon I will attempt to read that and understand it, because I do
see version and revision as two different things. Actually they are similar
but _to me_ apply at different levels and is probably where the confusion
quick read... looks like what I mean be version, is release in the documents
I probably will not remember that though:)

Yes, I need to read subject lines a little closer :)
You just hit my "RCS keywords dont work as I expect" button again today, its
kind of related and kind of bled over.
