--
--  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.
