tinc/src/protocol.h
Guus Sliepen ca6abd41ea Meta protocol overhaul. Tinc is now incompatible with previous versions,
furthermore this version does NOT work yet because of a problem with
sending keys (these should be converted to base36 or something like that).
It is possible to telnet to the tinc daemon now and type some commands
by hand though :).
