[Dirvish] Integrity check / checksums for stored files

I've been reading the awesome http://www.taobackup.com once more, and
noticed a single missing feature in dirvish: integrity checking.

i.e. the index doesn't contain a MD5/SHA-1/SHA-256 sum of the file
backed up, which means that any mucking with the backup can't be
discovered easily. (both MD5 and SHA-1 should still be sound for this,
although definitely unusable in a cryptographic context)

I guess this could be done with a post-script (I'm doing an fdupes -H
there already, which actually _adds_ to the risk of data corruption
across backups), but maybe adding this to the core of dirvirsh would
make sense, having it as default / configurable option?

Sadly, rsync doesn't support collecting this kind of information at
transfer-time (yet), otherwise this would be easier. Hmm.

Where is dirvish maintained these days? Is there an official github
project or similar, where one could send pull requests?

Cheers, and thanks for maintaining this awesome piece of software!
