Why is it that you don't want to be able to fully recreate a
build from history? That other build information is somewhat
important as it represents some state in history.

If you modify your processes you could make this a revprop on
the initial version of the directory - they are not versioned
and thus do not clutter things. The problem is that they don't
check out normally (you would have to do a propget and put the
output into your file) nor commit normally (required revprop
hook to allow changing it and taking the file and putting it
into the revprop via propset)

In a backwards compatible manner, this is a client issue and can
be build using what I described above. However, this is sub-optimal
for a number of reasons.

However, the concept of a file that does not get versioned - that just
scares me. In the old RCS days, that could happen with RCS if the
command ever thought you had binary in the file (high-bit ASCII, etc)
and thus it would only store the "current" version. I have lost the
history of a number of bits of source code from the 80's that I really
wish I had not lost. If it is too easy to set such a behavior in a
repository, the same could happen (either due to accident or malicious
intent). (The lack of ways to destroy data in the repository provides
a nice audit trail for companies that need to follow some documentation
