Adhearsion-JRuby monitored by god

A sample godrb watch for Adhearsion JRuby.

Caveats

• Note that godrb does not currently work under JRuby. You'll need a ruby manager like rvm or rbenv. That way, you can run your god under CRuby and your adhearsion app under JRuby.
• This script is not perfect. It occasionally produces empty or corrupt PID files. -_-
• This script makes a few assumptions.. tweak as necessary if any of this is inaccurate:
  • It assumes you use rvm
  • It assumes you use CentOS 6
