** Run backoffice processing on the repositories listed.  If no
** repository is specified, run it on the repository of the local checkout.
**
** This might be done by a cron job or similar to make sure backoffice
** processing happens periodically.  Or, the --poll option can be used
** to run this command as a daemon that will periodically invoke backoffice
** 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.
**

**
**    --logfile FILE          Append a log of backoffice actions onto FILE.
