The xbus is a simple interprocess communication bus based on publish/subscribe messaging over a UNIX domain socket that was designed for use in embedded devices with limited memory.
It consists of a daemon that acts as a message broker, a tiny library that provides basic functions for communication and a command line tool that is useful for debugging as well as for writing shell scripts.
