possibly new rsync trick: rotating snapshots

Martin,

Thanks for pointing this out to me--I've added a note on the web page near
the NFS discussion.  My machines are so slow that the network isn't a
bottleneck anyway, but this should be relavent to others, especially where
users don't need the transparency of a mounted system directory.
