It is written in Tcl/Tk script and will run on any computer or operating system in which Tcl/Tk is installed. This includes Windows, Unix, Linux and Macintosh. The script now provides graphical user interfaces to abc2abc, abc2midi, abc2ps, abcm2ps and yaps. You also need a midi player and a postscript viewer.
