46 \translator with no name and without assigning it to an
51 * \type Voice \times 2/3 { [c8 c16 c16 c16 c16] }
53 * fix singleStaffBracket

106 * strip EXEs before installing
108 * zip target for binary windows dist (JBR)
110 * revise documentation
112 * junking \skip req in lyrics

154 gs: Error: /undefined in draw_beam
157 * run texhash after installing .tex
159 * fix vertical alignment and stafflines
161 * GrandStaff needs more work -- I want a single word
162 `harpsichord' to the left of the grandstaff, not one on each
163 stave. (Organ staff -- with separate pedal -- but common
164 properties may be something to think about. Of course for
165 organ you want to be able to give stop indications on the way
166 through, so the \property Voice.Instrument would be a stop,
167 and \property GrandStaff.instrument would be PipeOrgan...)
169 * make Tie_req a "command" { <c g> ~ <c g> }

195 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
196 think about, analogous to pitch:
197 * { a4 a16 } c <-- duration of c?
198 * <a4 b8> c <-- duration of c?
202 * fix audio-items (don't use (input) requests, but copy data)
204 * junk My_lily_parser::abbrev_beam_type_i_

262 * disable spaces in TeX stuff
264 * handle ^C for tmp/file creation.
266 * dots & rest collisions.
274 * versioning for Feta
276 * the warning about the negative slur/tie length appears twice
279 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
282 * the bracket is ugly (wings are too parabolic, should be more circular)
284 * better hshift (dots, distance, head dependent)
286 * clefs (AG): The "8" should appear closer to the actual clef,
289 * put errorlevel in Input class
293 * integrate midi-elts from mi2mu and lily?

337 hunk, or on allegedly unsorted hunks in a diff, it may stop
338 without a trace of failure (create .rej file, print error or
339 dump core) and just ignore any further diffs.
343 f = fopen ("/dev/null", "r")

384 - bartypes (get rid of derived Span_bar_engravers)
389 - optimal pagebreaking.
391 * Unicode support? -> man 7 unicode
394 - detect of 16/8 bit files

476 - PostScript output (esp. Beams, Slurs, etc)
477 - Move all Score_elems, into libmutype.a
481 - Doc (C) stuff of sheet music
482 - a better format? SGML? TeX? Info?
