;;; HIP -- hack in progress
+;;;
+;;; status: hello-world
+;;;
+;;; This first working version needs rotty's g-wrap--tng.
+;;; (janneke's guile-gnome patches now in main archive).
+;;;
+;;; Try it:
+;;; 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: use latin1 encoding for gnome backend
+;;; * implement missing stencil functions
+;;; * implement missing commands (next, prev? page)
+
+;;; 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?
