The source branch is terabytes of source code. I want to restrict by
subdirectory, and flatten history to reduce the storage requirements.
As far as straightforward enough, yes, it's conceptually simple enough,
though I've got 600+ lines of Python code written for this so far (not
including unit tests or test inputs), and it's not done yet. It includes XML
parsing, YAML parsing, SVN interaction (with error checking), a flat file
database module (because the customer doesn't want to use gdbm or
similar), etc.

I guess I'm not entirely looking to modify existing history, so much as compress
the old stuff by flattening and restricting it, and then cloning the
recent history.
I can imagine a program to do this (at least to an extent) that doesn't require
admin access, but I'm hoping someone's already written it.
It's starting to sound like I'm going to need to write a bash script
to handle this.
