Fomus
Common Music Notation
This backend produces files in lisp syntax suitable for loading and
processing with Common Music Notation. The output setting for this
is :cmn. A .cmn extension is added to the base filename to make
the complete output filename. The file can be compiled and viewed
automatically if CMN is loaded and an .eps file viewing application
(a PostScript viewing application in Gnome or KDE in Linux or the
Preview application in OSX) has been found or is specified by the
user.
