    cat <<EOF
Usage: manpage-alert [options] [paths]
  Options:
    -h, --help          This usage screen.
    -V, --version       Display the version and copyright information.
    -f, --file          Show filenames of missing manpages
                        without any leading text.
    -p, --package       Show filenames of missing manpages
                        with their package name.
    -n, --no-stat       Do not show statistics at the end.

  This script will locate executables in the given paths with manpage
  outputs for which no manpage is available and its statictics.

  If no paths are specified on the command line, "/bin /sbin /usr/bin
  /usr/sbin /usr/games" will be used by default.
