[Cryptech Tech] Command line interface

[Rob Austein]

I looked for usable libraries with better licenses before suggesting
libcli.  Eg, there's the old Columbia-MM reimplementation of the
TOPS-20 COMND% JSYS (conceptual ancestor of the cisco CLI by way of
the Stanford Ethertip), but the code is old and crufty.

I think LGPL, while not great, is acceptable, in that it only requires
users to give away source to libcli itself.  In particular, it does
NOT GPL-contaminate everything to which it's linked.

I think that, if we want a usable command line interface soon, libcli
is probably the way to go.  We do have a few other things that we need
to get done before Berlin.
