-;;; HIP -- hack in progress
+;;; TODO:
;;;
-;;; This first working version needs Rotty's g-wrap--tng.
-;;; (janneke's guile-gnome patches now in main archive).
-;;; see also: guile-gtk-general@gnu.org
+;;; * 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. In the works.
+;;; * Maybe we need to have a unicode mapping somehow, we could
+;;; - use OpenType instead of Type1
+;;; http://lists.gnu.org/archive/html/lilypond-devel/2004-05/msg00098.html
+;;; - or fix the pangofc-afm-decoder and add it to Pango (no chance?)
+;;; or have fontconfig read AFM files
+;;; http://lists.gnu.org/archive/html/lilypond-devel/2004-05/msg00103.html
+
+;;; You need:
;;;
+;;; * Rotty's g-wrap >= 1.9.3 (or TLA)
+;;; * guile-gnome-platform >= 2.7.95 (or TLA)
+;;; * pango >= 1.6.0
+;;;
+;;; See also: guile-gtk-general@gnu.org
+
;;; Try it
;;;
-;;; * Use latin1 encoding for gnome backend, do
-;;; make -C mf clean
-;;; make -C mf ENCODING_FILE=$(kpsewhich cork.enc)
-;;; (cd mf/out && mkfontdir)
-;;; xset +fp $(pwd)/mf/out
+;;; [* Get cvs and tla]
+;;;
+;;; * Install gnome/gtk and libffi development stuff
+;;;
+;;; * Install pango, g-wrap and guile-gnome from CVS or arch:
+;;; see buildscripts/guile-gnome.sh
;;;
-;;; * lilypond-bin -fgnome input/simple-song.ly
+;;; * Build LilyPond with gui support: configure --enable-gui
;;;
-;;; todo: hmm --output-base broken?
-;;; ### cd mf && mftrace --encoding=$(kpsewhich cork.enc) --autotrace --output-base=feta-cork-20 feta20.mf && mf feta20.pfa out
-
-;;; Set XEDITOR and add
-;;; #(ly:set-point-and-click 'line-column)
-;;; to your .ly to get point-and-click
-
-;;; TODO:
-;;; * pango+feta font (see archives gtk-i18n-list@gnome.org and
-;;; lilypond-devel)
-;;; - wait for/help with pango 1.6
-;;; - convert feta to OpenType (CFF) or TrueType (fontforge?)
-;;; - hack feta20/feta20.pfa?:
-;;; * font, canvas, scaling?
-;;; * implement missing stencil functions
-;;; * implement missing commands (next, prev? page)
-;;; * user-interface, keybindings
-
-;;; Note: this install information is volatile
-;;; you'll probably want to pull all from
-;;; from guile-gnome-devel@gnu.org--2004 soon
-;;;
-;;; move this into workbook?
-
+;;; * Supposing that LilyPond was built in ~/cvs/savannah/lilypond,
+;;; tell fontconfig about the feta fonts dir and run fc-cache
