-- gcsd
--
-- gcsd the generic command sequencer daemon can be used to serialize
-- commands sent over various paralell communication channels to a
-- single command output. It can be seen as a multiplexer for any
-- kind of communication between a single resource and various clients
-- which want to submit commands to it or query information from it.
-- gcsd is written in C and Lua. The goal is to provide an easy to
-- understand high level API based on Lua which can be used to
-- implement the business logic of the so formed multiplexer daemon.
