A gem for simple, periodic, management of crons and shell calls.

Crossing Guard is simple way to wait unix commands, usually while other resource-heavy processes are running. Crossing Guard will de-dupe the waiting processes before running the queue.

Crossing Guard does not daemonize itself. If you do not have a regular process that will call Crossing Guard (e.g. to try new jobs), then you must run it 'blank' via cron or other daemon(ization).

Examples will come in time; for now, see the tiny source.
