** COMMAND: branch
**
** Usage: %fossil branch SUBCOMMAND ... ?OPTIONS?
**
** Run various subcommands to manage branches of the open repository or
** of the repository identified by the -R or --repository option.
**
** fossil branch new BRANCH-NAME BASIS ?OPTIONS?
**
** Create a new branch BRANCH-NAME off of check-in BASIS.
** Supported options for this subcommand include:
** --private branch is private (i.e., remains local)
** --bgcolor COLOR use COLOR instead of automatic background
** --nosign do not sign contents on this branch
** --date-override DATE DATE to use instead of 'now'
** --user-override USER USER to use instead of the current default
**
** DATE may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be
** replaced by a space, and it may also name a timezone offset
** from UTC as "-HH:MM" (westward) or "+HH:MM" (eastward).
** Either no timezone suffix or "Z" means UTC.
**
** fossil branch list|ls ?-a|--all|-c|--closed?
**
** List all branches. Use -a or --all to list all branches and
** -c or --closed to list all closed branches. The default is to
** show only open branches.
**
** fossil branch info BRANCH-NAME
**
** Print information about a branch
**
** Options:
** -R|--repository FILE Run commands on repository FILE
