-/**
- * @file qtmidi.c
- * @brief MIDI music player for MacOS X using QuickTime.
- *
- * This music player should work in all MacOS X releases starting from 10.0,
- * as QuickTime is an integral part of the system since the old days of the
- * Motorola 68k-based Macintoshes. The only extra dependency apart from
- * QuickTime itself is Carbon, which is included since 10.0 as well.
- *
- * QuickTime gets fooled with the MIDI files from Transport Tycoon Deluxe
- * because of the @c .gm suffix. To force QuickTime to load the MIDI files
- * without the need of dealing with the individual QuickTime components
- * needed to play music (data source, MIDI parser, note allocators,
- * synthesizers and the like) some Carbon functions are used to set the file
- * type as seen by QuickTime, using @c FSpSetFInfo() (which modifies the
- * file's resource fork).
