I tried setting up Galaxy to use Sun Grid Engine, but failed miserably.  I removed my config/job_conf.xml hoping Galaxy would revert to its default state, but jobs are no longer being dispatched.  I don't see any errors in the log. 

How can I get Galaxy to 1) use SGE, or 2) revert to its default state for running jobs.  The page, https://wiki.galaxyproject.org/Admin/Config/Performance/Cluster isn't 100% clear on how to set up a simply configuration for SGE.  I'd be happy to contribute mine as an example, if I can get it running.
