Muscript is a language for typesetting music, and a Perl script which translates this language either into PostScript, or into Encapsulated PostScript, or into MIDI, or into MusicXML, and there is a script muscriptps2svg to translate muscript into SVG. Muscript was written by Peter Billam to typeset his own compositions and arrangements. This page describes its History of Recent Changes.
