 The package consists of three mp3 files which aren't distributed with
 the game but are available on the upstream web page.
 .
 These files are:
 http://www.asc-hq.org/frontiers.mp3
 http://www.asc-hq.org/time_to_strike.mp3
 http://www.asc-hq.org/machine_wars.mp3
 .
 Everything else is just Debian packaging infrastructure.
