Blessed mother of Christ, please keep this readable
and protect us from segfaults. For thine is the clock,
the slave and the master. Until we return from main.

This is a stripped down version of the Georgi engine meant for use with
. As such serial-Steno features are disabled, chords are 16bits and
crap is removed where possible
