  48 Fix timestamp difference between .mp4 and .srt in AutoGuard (dash camera
  49 app for Android). Sometimes there is a difference of 1 second between
  50 the .mp4 and .srt file, and when they've been processed with datefn(1),
  51 the subtitles (GPS coordinates and timestamp) disappear.

  53 Usage: $progname [options] AG_FILES [...]
  54
  55 Options:
  56
  57   -h, --help
  58     Show this help.
  59   -q, --quiet
  60     Be more quiet. Can be repeated to increase silence.
  61   -v, --verbose
  62     Increase level of verbosity. Can be repeated.
  63   --version
  64     Print version information.
