Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden). Existing SHA1
digests retained for now as an audit trail.
While I can find little documentation out there, it seems to work
quite well for me (Subversion 1.4.4 + apr1). Thusfar it's seemed
quite speedy and useful. I'm thinking that fuse might be an interesting
way to get distfiles (curlftpfs) or source snapshots into pkgsrc.
