;;; HIP -- hack in progress
+;;;
+;;; 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
## ugh: get janneke's stuff -- should make build-config, I guess?
