# 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.
