+// DESCRIPTION:
+// MUS to MID conversion utility from PrBoom.
+//
+// This file supports conversion of MUS format music in memory
+// to MIDI format 1 music in memory.
+//
+// The primary routine, mmus2mid, converts a block of memory in MUS format
+// to an Allegro MIDI structure. This supports playing MUS lumps in a wad
+// file with BOOM.
+//
+// Another routine, Midi2MIDI, converts a block of memory in MIDI format 1 to
+// an Allegro MIDI structure. This supports playing MIDI lumps in a wad
+// file with BOOM.
+//
+// For testing purposes, and to make a utility if desired, if the symbol
+// STANDALONE is defined by uncommenting the definition below, a main
+// routine is compiled that will convert a possibly wildcarded set of MUS
+// files to a similarly named set of MIDI files.
+//
+// Much of the code here is thanks to S. Bacquet's source for QMUS2MID.C
+//
