** If only a single repository is named and --poll is omitted, then the
** backoffice work is done in-process.  But if there are multiple repositories
** 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).
**
**    --poll N                Repeat backoffice calls for repositories that
