This is the source code of XFD's MMCMP slave, for the curious.

MMCMP is a module compression format on the PC. It was created by Emmanuel
Giasson (Zirconia). The code for this slave came from the xmp package, by
Claudio Matsuoka <claudio@helllabs.org> et al, and originally came from
Oliver Lapicque's MODPlug source code.

The code has been tidied up and made endian-neutral. It still appears
worryingly incomplete, but it's all I have to go on, so it'll have to do...

This MMCMP slave has only been tested on a few files, so it may not be
entirely perfect. If you have a file it can't extract correctly, please
send it to me.
