;;; HIP -- hack in progress
+;;;
+;;; 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
+;;;
+;;; 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 $(pwd)/mf/out
+;;;
+;;; * lilypond-bin -fgnome input/simple-song.ly
+;;;
+;;; todo: hmm --output-base broken?
+;;; ### cd mf && mftrace --encoding=$(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
;;; move this into workbook?
