=head1 NAME
slxos-plugin - OpenSLX-script to install/remove an OS-plugin into/from an
installed vendor-OS.

=head1 DESCRIPTION
B<slxos-plugin> installs or removes specific functionality extensions into/from
an installed vendor-OS. That extension can be something rather simple (like
a boot-splash) or something rather complicated (e.g. the automatic detection,
installation and activation of the graphics driver most appropriate for the
booting client).
Installation of any plugin will result in some files being added to the
vendor-OS (they will live in /opt/openslx/plugins/<plugin-name>/). These files
can be accessed by the booting client.in order to integrate the required
functionality into the system.
