A library to run Ruby classes as daemons.
- process start
- terminal detach
- run as a user/group (root privileges drop)
- signal handling
- logfile
- pidfile, check for already running daemon
- may restart in a case of failure, by forking from watchdog
- may send exceptions to Airbrake and Exceptional
- Rails environment load at a late stage
- support for mutithreaded workers
- command-line argument parsing by use of the trollop library
- simple API for an application code
