  54 Create or update local Git branches that exist in remote repositories.
  55
  56 Usage: $progname [options] [remote [remotes [...]]]
  57
  58 Options:
  59
  60   -a, --all
  61     Create branches from all remotes. If this option is not specified,
  62     only "origin" or remotes specified on the command line are scanned.
  63     This option has no effect if any remotes are specified on the
  64     command line.
  65   -C, --create
  66     Create new branches locally. Without this option, only already
  67     existing branches will be updated.
  68   -c, --commit-branches
  69     Also create commit-* branches created by git-dangling.
  70   -f, --force
  71     Allow rewriting of local branches if fast-forward is not possible.
  72   -h, --help
  73     Show this help.
  74   -n, --dry-run
  75     Don't make any changes, print the commands that would be executed.
  76   -q, --quiet
  77     Be more quiet. Can be repeated to increase silence.
  78     One -q turns off the constantly updating branch name display.
  79   -u, --upstream
  80     Set local branches to track remote branches as upstream, similar
  81     functionality to "git branch -u" and "git push -u". When used with
  82     -a/--all, use the last remote in alphabetical order. If several
  83     remotes are specified, the last one is used.
  84   -v, --verbose
  85     Increase level of verbosity. Can be repeated.
  86   --version
  87     Print version information.
