.audio.mmlTuning
  The MML tuning of the A4 note, in Hz. The default is 440 Hz, but some
  people do not like that tuning, so you can change it. This setting only
  affects 24-TET sounds, and not overtone-based sounds.

.audio.mmlVolume
  MML volume, from 0 to 1; fractions are allowed. The default value is
  approximately one third. Set it to zero to disable MML sounds.

.audio.rate
  Sample rate to use for audio, in hertz. In order for audio to work at
  all, this value must be set.

.audio.standardSounds
  The name of the Hamster archive file containing the standard sounds. If
  not specified, then the standard sounds won't work.

.audio.waveVolume
  Wave volume, from 0 to 1; fractions are allowed. The default value is 1.
  If this is zero, then it will not load any sound effects, but MML sounds
  will still work (if .audio.buffer and .audio.rate are set correctly).

.autoSave
  If true, saves changes to the level and solution files when the program
  terminates. If false (default), they are only saved to the user cache
  database; to copy the changes to the level and solution files, you must
  use the .u command in SQL mode (-x), or use the -f switch.
