+RtMidi is a set of C++ classes (RtMidiIn, RtMidiOut, and API specific classes)
+that provide a common API (Application Programming Interface) for realtime MIDI
+input/output across Linux (ALSA, JACK), Macintosh OS X (CoreMIDI, JACK), and
+Windows (Multimedia Library) operating systems. RtMidi significantly simplifies
+the process of interacting with computer MIDI hardware and software. It was
+designed with the following goals:
+* object oriented C++ design
+* simple, common API across all supported platforms
+* only one header and one source file for easy inclusion in programming projects
+* MIDI device enumeration
