Wow, that would be useful, but it's a lot of work.  Multiple days
of full-time work, probably.

In the past, people who did that have usually started from a mailing
list archive like http://marc.info/?l=openbsd-cvs, and then looked at
CVS as required.

Starting from cvs2cl would be fine, too, and mostly equivalent.
Maybe even a bit easier because you see the revision numbers
right away.

You only need to look at changes involving two-component revision
numbers (x.y), those are on the MAIN branch, where all of -current
and all releases happen.  Four-component revision number (x.y.z.t)
are on branches, hence irrelevant.

To see whether an individual revision of a file was before or after
release, just look at the log for that file, and where the tag is.

Note that in rare cases, a release version of one file can be
*newer* than a post-release version of another file - but at
most by a few days, and only in those cases where Theo manually
retagged a file to put a last-minute bugfix into the release.

In extremely rare cases, one person may have changed several
files with one "cvs commit" command (and hence all with the
same date and commit message), and some of the resulting file
revisions may be part of the release, while others may not.

To get a rough first impression about the time range in which the
cutoff happened, look at:

Stuff *newer* than the "unlock" change is *usually* post-release
(except when Theo retagged something), stuff *older* than the
"unlock" change is *usually* in the release - but a few changes
may have gone in before the unlock change.  So be careful with
changes in the timerange of about two days before to about seven
days after.  Some of them may be in the release, some post-release,
independent of their chronological ordering, even though they are
all on the same branch!

Again, ignore everthing with four-component numbers, use all the rest.

Not from cvs2cl, no.  That is a limitation of that particular
(quick and dirty) script, not a limitation of CVS itself.

You *can* see that from cvs2cl output.
Those would have four-component revision numbers.

Nothing else is going on in the tree.  In OpenBSD, side branches
for development are strongly frowned upon and are used extremely
rarely, and none have been active for some years now as far as i

Your biggest problem is that you are trying to figure out how a
tiger looks like by asking specific questions about its roots,
its stem, and its leaves.

In git, everything revolves around commits and files are of
very little importance.

In CVS, the basic concept is completely different.  Everything
revolves around files and their revisions.  The revisions of one
file are independent of the revisions of any other file, and the
notion of a "commit" is practically meaningless.  Most definitely,
commits do not have parents and children, ordering them chronologically
is completely useless, and in particular tells you nothing about
which revisions of which files are or are not part of a release.
