UUCP `v' Protocol
=================

   The `v' protocol is used by UUPC/extended, a PC UUCP program.  It is
simply a version of the `g' protocol which supports packets of any
size, and also supports sending packets of different sizes during the
same conversation.  There are many `g' protocol implementations which
support both, but there are also many which do not.  Using `v' ensures
that everything is supported.
