=head1 NAME

MondoRescue::Inventory, part of the mondorescue.org

=head1 DESCRIPTION

This modules provides inventory functions for the Mondorescue project in order to report
the precise context of the system to be archived (Hardware, Firmware and Software as much as possible)
This module aims to be OS independent
