Why don't you use the cvs vendor branch to do most of the work for you,
rather than generating deltas yourself?

Every day you'd get the latest release tree from BK and do a cvs import of
this into your local repository, followed by the cvs checkout -j -j and
cvs commit to merge the changes into the main trunk - CVS keeps track of
the state the BK repository was in when it was last imported.

If you do this right, this should only bring up problems in the checkout
-j -j stage when some locally committed change conflicts with an imported
change, which is something you'd have to fix manually anyway.

Oh, and BTW the instructions that cvs import prints out about doing the
cvs checkout -j -j aren't quite right, you should really use the release
tags you gave to cvs import rather than the :yesterday it recommends.

I can give more detail on this approach if you're interested - we don't
import the linuxppc tree, automate it or do it daily, but do have a
standard procedure for this kind of handling of externally managed code
with CVS.
