Daemons provides an easy way to wrap existing ruby scripts (for
example a self-written server) to be run as a daemon and to be
controlled by simple start/stop/restart commands. You can also call
blocks as daemons and control them from the parent or just daemonize
the current process. Besides this basic functionality, daemons offers
many advanced features like exception backtracing and logging (in case
your ruby script crashes) and monitoring and automatic restarting of
your processes if they crash.
