rq is an __experimental__ tool used to manage nfs mounted work queues. multiple instances of rq running from multiples hosts can work from these queues to distribute processing load to 'n' nodes - bringing many dozens of otherwise powerful cpus to their knees with a single blow. clearly this software should be kept out of the hands of radicals, SETI enthusiasts, and one mr. jeff safran. rq operates in one of the modes create, submit, feed, list, delete, query, snapshot, or help. depending on the mode of operation and the options used the meaning of mode_args may change, sometime wildly and unpredictably (i jest, of course).
