I tried cvsps and it doesn't generate the patchsets properly. In
bkcvs, the revision log is stored as a log for the ChangeSet file and
the rest of the files contain the (Logical revision ...) text in their
log. Cvsps doesn't properly match those. You can get several patches
for the same revision or you can get them in a different order. Even
worse, the ChangeSet log (together with the BKRev tag you use) for a
given logical revision can appear before the actual patch for the
files corresponding to that patch (that's why the bkrev tagging is
There might be a possibility to use the cvsps generated patches but
re-sorted after the logical revision and do a "cvs log ChangeSet -r
<logical_rev>" to get the actual log message.
Another possibility would be to use the patches sent to the
bk-commits-head mailing list (also accessible through
gmane.linux.kernel.commits.head) and apply them one by one. I'm not
sure if they can be cleanly apply in the order they are posted though
(I don't know bitkeeper's internals).
