As the cvs history will tell you, it is a set of routines for
building and parsing mbuf chains. It is useful for processing
requests and replies in vaguely RPC-like protocols, and it's in the
tree because nwfs and smbfs use it (I think it was made an optional
component to avoid the small extra bloat in kernels that don't use
these). The NFS code could probably also benefit from using it.
