Notes:

Release Name: ARC Queue Tools

Notes:
Command queueing tools by Dan Marcus.

Set ARC_TOOLS in each script to a directory where the queue and logs will be written.  Then use:

arc-queue command arg ...

to queue a command, and:

arc-qrunner

to run the commands in the queue.

Normally arc-queue is called from pipeline/bin/schedule or pipeline/bin/XnatPipelineLauncher (to catch the auto-run pipelines as well), and arc-qrunner is called by a cron job.

See the comments at the head of each file for more information.
