runit

This formula does not install runit as a replacement for init.
The service directory is $HOMEBREW_PREFIX/var/service instead of /service.

A system service that runs runsvdir with the default service directory is
provided. Alternatively you can run runsvdir manually:

     runsvdir -P $HOMEBREW_PREFIX/var/service

Depending on the services managed by runit, this may need to start as root.
