In the sources of the memory layout tool ;-). Really, it isn't something
that's documented because it's not intended to be editted.

A .mlt file is the save file of the Memory Layout Tool. The MLT uses the
.mlt file to *generate* a .ldi and .h file. You can only generate those if
you have the MLT, so if you don't, there's no point editting the .mlt file!
Or if you do have the MLT, then that's what you use to edit the file :).

might at least help a little.
