Philip's Music Writer is a program for typesetting music. It reads text files as input, and generates PostScript as output. It can also write simple MIDI files for proofhearing purposes. PMW is written in C and is freestanding; that is, it does not require additional processing software. It is a Linux/Unix port of a program that has run for over a decade on Acorn systems, where it was known as Philip's Music Scribe.
