** COMMAND: backoffice*
**
** Usage: backoffice [OPTIONS...] [REPOSITORIES...]

** on collection of repositories.
**
** If only a single repository is named and --poll is omitted, the the
** backoffice work is done in-process.  But if there are multiple respositories
** or if --poll is used, a separate sub-process is started for each poll of 
** each repository.
**
** Standard options:
**
**    --debug                 Show what this command is doing.
**
**    --logfile FILE          Append a log of backoffice actions onto FILE.
**
**    --min N                 When polling, invoke backoffice at least
**                            once every N seconds even if the repository
**                            never changes.  0 or negative means disable
**                            this feature.  Default: 3600 (once per hour).
**
**    --nodelay               Do not queue up or wait for a backoffice job
**                            to complete. If no work is available or if
**                            backoffice has run recently, return immediately.


**
**    --poll N                Repeat backoffice calls for repositories that
**                            change in appoximately N-second intervals.
**                            N less than 1 turns polling off (the default).
**                            Recommended polling interval: 60 seconds.
**
**    --trace                 Enable debugging output on stderr
**
** Options intended for internal use only which may change or be
** discontinued in a future release:
**
**    --nolease               Always run backoffice, even if there is a lease
**                            conflict.  This option implies --nodelay.
