This is silly. I can see that someone decided to restrict targeting
to one ship as a difficulty setting, but that's not a very good way
to achieve different levels of difficulty.
Also added more music and slowed down RE.ogg.
The title is chosen because it is both a warm-up for me writing music with ABC
and CSound, it will also be used in the first levels of Starfighter where the
player has to warm up.
Two basic, unfinished songs, written in ABC notation are added. The Makefile
will convert the .abc files to MIDI files, which are rendered using Csound. At
the moment, Csound is set up to use the Fluidsynth engine to render sound using
soundfonts, and the reverbsc opcode is used to add a reverb effect.
ABC notation is much easier to write music in than using "raw" Csound score
notation. Also, the abcm2ps utility can create very nice sheet music from ABC
files.
