There's a little documentation in the doc/ directory, but not a whole
lot. I'd like to add some online help to patchwork though.

There's no expected flow; it's really up to the maintainers of the
project. It's also why the patch states are configurable.
However, this is generally what we do for powerpc:
When the maintainer (benh) is looking for patches to merge, he scans the
patchwork list for patches in one of the 'Action Required' states (ie,
New and Under Review). For each of these, they are either:
* Added to a 'merge' bundle;
* Allocated to a sub-maintainer; or
* Updated to a Rejected/Superseded/Not Applicable/etc state
Then the merge bundle is downloaded, and applied with a custom script,
which updates the patchwork states accordingly (using pwclient).

I've just pushed a change for this. Had it sitting in my local tree for
a while :/

Fixed and pushed.

You can use the patch 'hash' for this. It's a bit hacky for now, but
$ python ./apps/patchwork/parse.py --hash < foo.patch
This hash is based on the content of the patch, minus stuff that's
likely to change (eg line numbers). You can then use this hash to match
a patch in patchwork:
$ pwclient update -s Accepted -c <commit-ref> -h <hash>

Which bits? patchwork should be VCS-neutral - if there's anything that's
too specific to git, then I can look at making it work with svn too.
