** 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 close ?OPTIONS? BRANCH-NAME ?...BRANCH-NAMES?
**
** Close one or more branches by adding the "closed" tag
** to them. It accepts arbitrary unambiguous symbolic names but
** will only resolve checkin names and skips any which resolve
** to non-leaf or closed checkins. Options:
** -n|--dry-run do not commit changes and dump artifact
** to stdout
** -v|--verbose output more information
** --date-override DATE DATE to use instead of 'now'
** --user-override USER USER to use instead of the current default
**
** > fossil branch current
**
** Print the name of the branch for the current check-out
**
** > fossil branch hide|unhide ?OPTIONS? BRANCH-NAME ?...BRANCH-NAMES?
**
** Adds or cancels the "hidden" tag for the specified branches or
** or checkin IDs. Accepts the same options as the close
** subcommand.
**
** > fossil branch info BRANCH-NAME
**
** Print information about a branch
**
** > fossil branch list|ls ?OPTIONS? ?GLOB?
**
** List all branches. Options:
** -a|--all List all branches. Default show only open branches
** -c|--closed List closed branches.
** -r Reverse the sort order
** -t Show recently changed branches first
**
** The current branch is marked with an asterisk.
**
** If GLOB is given, show only branches matching the pattern.
**
** > 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
** ("auto" lets Fossil choose it automatically,
** even for private branches)
** --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.
**
** Options valid for all subcommands:
**
** -R|--repository REPO Run commands on repository REPO
