Sam's notes:
"Here is a patch that supports directory paths, documentation for the
above and decanonicalization of of supplied paths. Here are tests I
have run:
* Build with both transarc and non-transarc paths and examined
dirpath.o
* Build with roughly FHS-style paths and tested on Debian
* confirmed that bos salvage works even when salvager not in
/usr/afs/bin
(it gets the log correctly too)
* confirms that bos getlog can get logs from /usr/afs/logs even when
/ur/afs/logs
is /var/lib/openafs/logs
* confirmed that bos getlog can get /etc/motd
