This is an assorted collection of stuff that will be done, might be
done, or is an idea that I want to think about
Most of the items are marked in the code as well, with full explanation.

-**********************
-HKN buglist:
+ * include MIDI list
-\bar || ook dunne streepjes? Sluit de balk niet af! (soms met de
-ruimte van een hele maat erachter (bij unmatching staffs)
+ * make separate translation property list.
-Hele rusten ook in andere maatsoort dan 4/4 (en centreren in de maat)
+ * make GNU style webpages.
-noten staan vaak te dicht aan de rechterkant van de maatstreep.
+ * There seems to be an install error in lilypond-1.0.0. Most of the
+ files in the "init" directory don't get installed in the
+ /usr/local/share/lilypond directory. The files installed are of
+ the form feta*.ly. In particular init.ly doesn't get installed.
+ I installed the files by hand and then the system seems to work.
-optie om nummers/markers boven maatstrepen te zetten
+ * midi_instrument -> midiInstrument
-tekst staat erg ver van notenbalken af
+ * horizontal centering of dynamics
-waarom geen ; achter dingen in \paper? (\textwidth 180\mm)
-(sowieso: wanneer wel en geen ; ?)
+ * \font\fontA=feta20.afm (.afm?)
-Onduidelijk wanneer wel en geen \ voor een woord. Maak liever
-verplichte regels
+ * gzip RH manpage
-implementeren versieringen door duration *0 ofzo? (geeft nu assertion,
-zie duration0.ly)
+ * stable make/config stuff
-Triolen enzo: het zou handig zijn als je het cijfer "3" ook _tussen_
-twee noten kon plaatsen. Dat is bijvoorbeeld nodig in
-c4*2/3 c8*2/3
+ * stemup/stemdown; see test/updown.fly
+ - check examples; add \type Staff hither and thether
----------------\
-\bar "||" \meter 6/8; op het eind van de regel staat door elkaar

+ * GrandStaff needs more work -- I want a single word
+ `harpsichord' to the left of the grandstaff, not one on each
+ stave. (Organ staff -- with separate pedal -- but common
+ properties may be something to think about. Of course for
+ organ you want to be able to give stop indications on the way
+ through, so the \property Voice.Instrument would be a stop,
+ and \property GrandStaff.instrument would be PipeOrgan...)
