service 
service will install / un-install, start / stop, and run a program as a service (daemon). Currently supports Windows XP+, Linux/(systemd | Upstart | SysV), and OSX/Launchd.
Windows controls services by setting up callbacks that is non-trivial. This is very different then other systems. This package provides the same API despite the substantial differences. It also can be used to detect how a program is called, from an interactive terminal or from a service manager.
BUGS
- Dependencies field is not implemented for Linux systems and Launchd.
- OS X when running as a UserService Interactive will not be accurate.
