-;;;
-;;; status: hello-world
-;;;
-;;; This first working version needs rotty's g-wrap--tng
-;;; and janneke's guile-gnome patches, instructions below.
-;;;
-;;; Try it:
-;;; lilypond-bin -fgnome input/simple-song.ly
-;;;
-
-;;; TODO: pango+feta font (wait for pango 1.6?)
-
-;;; 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?
