* 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.
