** 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?
**

**
**        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

  *  The default "ssh" command on Windows is changed to "ssh" instead of the
     legacy "plink", as ssh is now generally available on Windows systems.
