  32 Frontend to task(1) (Taskwarrior) or timew(1) (Timewarrior), depending
  33 on what the script is called. If the file name of the script is "t",
  34 call Taskwarrior, if it's "tw", call Timewarrior. Other names result in
  35 an error.

  37 Commits the result of every command to Git.

  39 Usage: $progname [options] TASK_COMMAND
  40        $progname --is-active
  41        $progname angre
  42
  43 Options:
  44
  45   -h, --help
  46     Show this help.
  47   --is-active
  48     Check that the task repository is marked as active, that the t.active Git
  49     config value is set to "true". If it's anything else, the script will abort
  50     with exit value 1.
  51   --version
  52     Print version information.
  53
  54 "$progname angre" assumes that $taskdir is version controlled by Git and
  55 will throw away the newest commit. If the repository is modified in any
  56 way, the operation aborts.
