-;;;; output-gnome.scm -- implement GNOME canvas output
-;;;;
-;;;; source file of the GNU LilyPond music typesetter
-;;;;
-;;;; (c) 2004 Jan Nieuwenhuizen <janneke@gnu.org>
-
-;;; TODO:
-;;;
-;;; * Figure out and fix font scaling and character placement
-;;; * EC font package: add missing X font directories and AFMs
-;;; * User-interface, keybindings
-;;; * Implement missing stencil functions
-;;; * Implement missing commands
-;;; * More information in stencils, e.g., location and grob tag.
-;;; * Embedded Lily:
-;;; - allow GnomeCanvas or `toplevel' GtkWindow to be created
-;;; outside of LilyPond
-;;; - lilylib.
-;;; * Release schedule and packaging of dependencies. This hack
-;;; depends on several CVS and TLA development sources.
-
-;;; You need:
-;;;
-;;; * Rotty's g-wrap--tng TLA, possibly Janneke's if you have libffi-3.4.
-;;; * guile-gnome TLA
-;;; * pango CVS (ie, > 2004-06-12)
-;;;
-;;; See also: guile-gtk-general@gnu.org
-
-;;; Try it
-;;;
-;;; * Get cvs and tla
-;;;
-;;; * Install gnome/gtk and libffi development stuff
-;;;
-;;; * Install pango, g-wrap and guile-gnome from CVS or arch:
-;;; see buildscripts/guile-gnome.sh
-;;;
-;;; * Build LilyPond with gui support: configure --enable-gui
-;;;
-;;; * Supposing that LilyPond was built in ~/cvs/lilypond, tell X about
-;;; feta fonts:
-"
-ln -s ~/cvs/lilypond/mf/out ~/.fonts
-mkfontdir ~/.fonts
-xset +fp ~/.fonts
-"
-;;;
-;;; * Setup environment
