[OpenAFS-devel] afs-nfs translator

[Derek Atkins]

Note that on many platforms you can still export AFS via NFS in
read-only mode even without the AFS-NFS translator.  The translator is
useful mostly for RW access, which IMHO isn't always necessary.  It is
also useful for the few cases where you can't NFS export a "mounted"
filesystem.
