There's the INSTALL file and the README file.  They're not particularly
great but they cover the basics.  To quote one of the gatekeepers in
the thread that preceeded this one:

"Yeah.  I just wish we could ship something that didn't suck so much."

It's an add-on package for the amanda system, which you can find at
www.amanda.org.  The idea is to add some AFS-awareness to amanda and
improve on the original AFS backup system.

yes.

essentially, it performs a "vos dump -time" in order to capture incremental
differences.

Yes.  In fact if someone wanted to write a better guide to use I'd be
more than happy to include it in the base package
