-;;; HIP -- hack in progress
-;;;
-;;; You need:
-;;;
-;;; * guile-1.6.4 (NOT CVS)
-;;; * Rotty's g-wrap--tng, possibly Janneke's if you have libffi-3.4.
-;;;
-;;; see also: guile-gtk-general@gnu.org
-;;;
-;;; Try it
-;;;
-;;; * If using GUILE CVS , then compile LilyPond with GUILE 1.6,
-;;;
-;;; PATH=/usr/bin/:$PATH ./configure --enable-config=g16 ; make conf=g16
-;;;
-;;; * Install gnome/gtk development stuff and g-wrap, guile-gnome
-;;; see buildscripts/guile-gnome.sh
-;;;
-;;; * Use latin1 encoding for gnome backend, do
-;;;
-"
- ./configure --prefix=$(pwd) --enable-config=g16
- make -C mf conf=g16 clean
- make -C mf conf=g16 ENCODING_FILE=$(kpsewhich cork.enc)
- (cd mf-g16/out && mkfontdir)
- xset +fp $(pwd)/mf-g16/out
-"
-;;;
-;;; * Setup environment
-"
-export GUILE_LOAD_PATH=$HOME/usr/pkg/g-wrap/share/guile/site:$HOME/usr/pkg/g-wrap/share/guile/site/g-wrap:$HOME/usr/pkg/guile-gnome/share/guile
-export LD_LIBRARY_PATH=$HOME/usr/pkg/g-wrap/lib:$HOME/usr/pkg/guile-gnome/lib
-export XEDITOR='/usr/bin/emacsclient --no-wait +%l:%c %f'
-"
-;;; * For GNOME point-and-click, add
-;;; #(ly:set-point-and-click 'line-column)
-;;; to your .ly; just click an object on the canvas.
-;;;
-;;; * Run lily:
-"
-lilypond-bin -fgnome input/simple-song.ly
-"
-
-
-;;; 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
-;;; * user-interface, keybindings
-;;; * cleanups: (too many) global vars
-;;; * papersize, outputscale from book
