Hi,

For consistancy with future parameters handling maintaince, I need to
alter the help text format like the following, which does not vary too
much from the original:

-------------------------------------------------
grml-debootstrap - wrapper around debootstrap for installing Debian

Usage: grml-debootstrap [options]

Bootstrap options:

  -m, --mirror=URL       Mirror which should be used for apt-get/aptitude.
  -i, --iso=mnt          Mountpoint where a Debian ISO is mounted to, for use
                           instead of fetching packages from a mirror.
  -r, --release=name     Release of new Debian system (default: stable).
  -t, --target=target    Target partition (/dev/...) or directory.

      --debopt=params    Extra parameters passed to the debootstrap.

                           $TARGET in grub syntax, like hd0,0 for /dev/sda1.
      --grub=device      Target for grub installation. Use grub syntax for
                           specifying, like hd0 for /dev/sda.

      --interactive      Use interactive mode (frontend).

Other options:

  -h, --help             Print this usage information and exit.

-------------------------------------------------

This is the format that complies with most GNU C/C++ program helps.
What do you think, mika? I altered the order of the parameters as
well. Please comment.

If we can agree upon the content (including the sections, order...
everything but format) of the help text, I can move forward and code
the .clp script.

thanks
