If done on checkin, it will generate all kinds of problems.  First of
all, since the revision has a hash of the manifest, which has a hash
of the file, changing the file will change the hash of the file, which
will change the manifest, which will change the hash of the manifest,
which will change the revision, which will change the revision hash
(ID), so you need to change that in the file...  Now, let's all sing:

Well, substitution could happen on export, as long as the keywords are
canonicalised back.  If that's to happen, I actually like the
subversion way, where you have to say explicitely which keywords
should be expanded.  If monotone is to have keywords, I suggest doing
it that way (perhaps by creative use of .mt-attrs).

Either way, keyword expansion is an error-prone business which
requires great thought and care, so let's not rush into it.  We have
bigger issues to deal with, so I suggest we put the keyword thought on
hold for now.

Cheers,
Richard
