-;;; HIP -- hack in progress
+;;; TODO:
;;;
+;;; * Figure out and fix font scaling and character placement
+;;; * EC font package: add missing X font directories and AFMs
+;;; * User-interface, keybindings
+;;; * Implement missing stencil functions
+;;; * Implement missing commands
+;;; * More information in stencils, e.g., location and grob tag.
+;;; * Embedded Lily:
+;;; - allow GnomeCanvas or `toplevel' GtkWindow to be created
+;;; outside of LilyPond
+;;; - lilylib.
+;;; * Release schedule and packaging of dependencies. This hack
+;;; depends on several CVS and TLA development sources. In the works.
+;;; * Maybe we need to have a unicode mapping somehow, we could
+;;; - use OpenType instead of Type1
+;;; http://lists.gnu.org/archive/html/lilypond-devel/2004-05/msg00098.html
+;;; - or fix the pangofc-afm-decoder and add it to Pango (no chance?)
+;;; or have fontconfig read AFM files
+;;; http://lists.gnu.org/archive/html/lilypond-devel/2004-05/msg00103.html

-;;; * Install gnome/gtk development stuff and g-wrap, guile-gnome
+;;; * Install pango, g-wrap and guile-gnome from CVS or arch:
