ENP is used as the notational front-end in PWGL.
Currently, PWGL runs under Mac OS X and Windows XP operating systems. PWGL is distributed in two different configurations: as a standalone application, called PWGL Application, that is targeted mainly to end users, and as a developers version, PWGL Binaries, that is made available as a pre-compiled module that can be loaded on top of LispWorks.
