Tune File Format

This file defines the .tune music file format.

Following is a simple example of the beginning parts of the Super Mario Brothers theme song:

660 100
0 150
660 100
0 300
660 100
0 300
510 100

Full specification

1. Each line in the file is <frequency> <duration>
   1. <frequency> is the frequency of the beep in Hz or 0 for silence
   2. <duration> is the duration of the beep in milliseconds
2. Line ending is unix format
3. File extension is .tune
4. Although not necessarily part of the tune, consider adding a silence at the end so that looped playback sounds good :-)

Note: this is compatible with the GRUB_INIT_TUNE when using a TEMPO of 60,000 (bpm).
