The command we ended up using back in May 2011 when we did this looked
like the following. It's been two years, but I'm pretty sure these two
scripts is all we ended up using.
- We had a master dump of the entire brc-jobs repository.
- Target repository name was "brc-jobs-zp" (CLCODE)
- It takes the dump and splits it into a smaller chunk (CLPATH).
- Had to edit the script for each new client/path that we wanted to
split out.
It does *not* attempt to rebase the individual projects up to the root
directory. It *is* possible by using 'sed' to do this in the resulting
dump file, but it is trick.

The mirror to this was the script that created the new SVN repository
and loads in the individual dump.
Note the commented out 'sed' lines where we attempted to rebase
individual project folders back up to the root of the repository. They
didn't work, so we ended up just doing a move operation in the
TortoiseSVN repository browser.
- It changes the UUID of the newly created repository to be something
unique instead of using the old repo's UUID.
- Had to be edited anew for each new client/path.

I do wish I could have figured out the 'sed' commands to move a project
from /Z/ZP_SingleJobs/JOBNR to be just /JOBNR in the repository, but
there wasn't time.
For rebasing, that's probably your missing piece... which I don't have.
