** 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 current
**
**        Print the name of the branch for the current check-out
**
** >  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
**
**        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
**        --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 FILE       Run commands on repository FILE
