[PATCH] debootstrap new options to list and check suite

[Julien Kerihuel <j.kerihuel@openchange.org>]

Hi List,

Please find attached a small patch which add new options to debootstrap
script and manpage:

        --list-suite 		list available debootstrap suites
        --check-suite=A		check if suite A is supported by debootstrap

These options may be useful to developers willing to have a build system
where they can customize the debootstrap SUITE parameter and perform
sanity check before executing the script (e.g. ./configure
--with-suite=sarge).

The patch also adds --version to the man page.


Cheers,
Julien.
