+;;;; * .cff MUST NOT be in fc's fontpath.
+;;;; - workaround: remove mf/out from ~/.fonts.conf,
+;;;; instead add ~/.fonts and symlink all /mf/out/*otf there.
+;;;; - bug in fontconfig/freetype/pango?
+
+;;; * check: blot+scaling
;;; * Figure out and fix font scaling and character placement
;;; * EC font package: add missing X font directories and AFMs
;;; * User-interface, keybindings
;;; - 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.
+;;; * Release schedule and packaging of dependencies.
+;;; - g-wrap-1.9.3 is already in incoming.
+;;; - guile-gnome-platform-2.8.0 will probably be packaged early 2005.
;;; 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)
+;;; * Rotty's g-wrap >= 1.9.3
+;;; * guile-gnome-platform >= 2.7.97
+;;; * pango >= 1.6.0
;;;
;;; See also: guile-gtk-general@gnu.org
;;; Try it
;;;
-;;; * Install gnome/gtk development stuff
+;;; * Install gnome/gtk and libffi development stuff
;;;
-;;; * Install g-wrap and guile-gnome, see buildscripts/guile-gnome.sh
+;;; * Install [pango, g-wrap and] guile-gnome from source,
+;;; see buildscripts/guile-gnome.sh
;;;
+;;; * Build LilyPond with gui support: configure --enable-gui
+;;;
+;;; * Supposing that LilyPond was built in ~/cvs/savannah/lilypond,
+;;; tell fontconfig about the feta fonts dir and run fc-cache
