2.3.3:
  - fixed bug in updater related to io files (see tmp_stdin in jobqueue.rb)
  - [IMPORTANT] removed feature where stdin jobs could contain comments ('#').
    input lines are now taken literally __except__ blank lines, which are
    still ignored.
  - added ability to dump stdin/stdout/stderr for any job

      rq q stdout 42

      cat jids | rq q stdout - 

  - added ability to dump stdin/stdout/stderr pathnames for any job
      rq q stdout4 42

      cat jids | rq q stderr4 - 
  - rotate was made more robust and tolerates nfs errors to some degree

2.3.2:
  - added 'rq q io' command
  - streamlined 'rq q status' output considerably
  - fixed few small bugs in util.rb 
  - patched yaml inline behaviour for syck in 1.8.4.  backward compatible with
    older ruby versions - at least through 1.8.2.
  - changed naming scheme for rotation and added automatic attempt to compress
    the rotation
  - made shutdown via ctrl-c when running from commandline (as opposed to
    daemon) quieter
  - fixed a few bad exit codes, for example creating a queue exited with
    $?==1, it is now correctly 0
  - added support for job stdin to be provided and stdout/stderr captured.
    for instance

      rq queue submit cat --stdin=input_for_cat.txt

      cat input_for_cat.txt | rq queue submit cat --stdin=-

      rq queue submit cat --stdin=- < input_for_cat.txt

    stdout and stderr are stored in the queue directory in a file named by
    jid.
  - changed behaviour of reading jobs from stdin: ***IMPORTANT*** : it's now
    **REQUIRED** to provide a '-' as the argument for any command that should
    read from stdin.  for instance one would use

      rq queue submit - < joblist
    or
      jobgenerator.rb | rq queue submit -

    vs the old

      rq queue submit < joblist
    or
      jobgenerator.rb | rq queue submit


    the distiction was added to make running submissions from scripts/cron
    (where STDIN.tty? == false) easier and providing the job stdinput on stdin
    possible.
  - added a restart mode to restart a feeder : rq q restart
  - modes shutdown, stop, and restart now return a non-zero exit code if they
    fail to signal the feeder, zero otherwise
  - fixed bug with restart mode whereby re-exec failed due to falsely thinking
    pid was locked (it is - but only by the current process!)
  - added default bin dir underneath q dir.  this dir is added to the path
    before excuting commands to it's an easy place to put things where they'll
    be found
2.3.1:
  - added 'stage' option to submit mode, which allows submission in a 'holding'
    state.  thanks to Juan.Fernandez@eu.Takata.com for this fix!
2.3.0:
  - added ability to set state=holding
  - added holding to statuslister
  - ENV['RQ_JOB'] now has yaml dump of entire job when run
  - some minor mods to updater/deleter
2.2.0:
  - added start, stop, shutdown, and feeder modes - thanks to mikael borg for
    suggestion
  - improved query usage
  - added credits section to help
2.1.0:
  - enhanced status reporting
  - fixed bug where rotating
