+preMudelaExample[eps]{}, and change it in document body sometimes.

+. * Lyrics and scripts collide.
+. * a note with a circle after it, meaning:
+
+ note + circle = note + 1/4 of its length
+
+ the circle is like a dot that's not filled in. for example, on
+ page three, the c-sharp on the second line should be a quarter with

+. * Aha, the problem is the new TeX code generation for changing fonts.
+> (The explanation below is mostly intended for Han-Wen and Jan)
+> Before, the font was changed with macros declared separately for
+> pure TeX and LaTeX, but now all the fonts are declared directly in
+> the generated code using the low-level TeX commands. This circumvents
+> the fontencoding mechanism of LaTeX and is a potential source of
+> problems also for us users of the Latin-1 character set.
+> I think it still works since the inputencoding latin1 is
+> declared by ly2dvi, but it still means that e.g. an o with
+> umlaut is typeset as a combination of the two symbols 'o' and
+> 'umlaut' instead of as a single character, as would be the case
+> if fontencoding OT1 had been used. This shouldn't give any
+> difference in layout, though. One of the main argument for using
+> fontencoding OT1 is for the hyphenation mechanism to work, an
+> argument that's clearly irrelevant in our application. Yet we
+> see the problem for August.
+. * Abstraction for engravers:
+. * make "in-between" engraver (Tie, Extender)
+. * make wide_spanner_engraver (line_group_spanner, staff_symbol)
+. * do scaled fonts generally
+. * The Lilypond accidental symbols are available through the TeX macros,
+\textflat, \textsharp and \textnatural defined in the init file
+lilyponddefs.tex. All the symbols are defined in the files fetaXX.tex

+My wish list for lyrics. I dream of a time when I will have enough time to
+become familiar enough with the source code to be able to implement some of
+these myself, but I don't know when that will be, so I thought I'd "publish"
+my suggestions in case someone else is in a position to give them some
+priority. Otherwise, perhaps they could go on the todo list?
+
+If any of these are already implemented, please let me what the syntax is to
+use them!
+
+1. Stanza numbering. Numbering at the beginning of a song with the number
+set to the left of the first note. It would also be nice (but not as
+important) to be able to have some form of automatic numbering at the
+beginning of each new line. This would make it easier to follow songs with a
+large number of stanzas.
+
+2. Hyphens between syllables. At the moment there appears to be no easy way
+to position a hyphen mid-way between the syllables it breaks.
+
+3. Notes centred above/below lyrics rather than left-aligned.
+
+4. It would be very nice to be able to build some kind of phrasing into the
+lyrics of hymns, etc, so that the first words of a phrase are left aligned
+with each other, the last words are right aligned, and the words in between
+are centred.
+
+5. In a song, with (say) four stanzas and a chorus, it would be nice to be
+able to vertically align the chorus midway between the staves.
+
+6. It would be nice to be able to put vertical brackets either side of a
+repeated section with different words for each repeat.
+
+. * Give # lines in linebreaking.
+. * arrows on slurs.
+. * rewrite context defs using Scheme
+. * \selectmusic to cut pieces from music.
+. * TODO: merge atom & molecule; make tree from molecule.
+. * Align_element::padding ?
+. * typo checks on property names?
+. * use streambufs and iostream
to provide IO handling for TeX stream, mudela stream, data-file.
-
- * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
-
- * strip EXEs before installing
-
- * zip target for binary windows dist (JBR)
-
- * text continuations

- * fix vertical alignment and stafflines
-
- * 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...)

+> Would it be hard to add support for proper dynamics in MIDI output? I
+> would really like to have this feature...
+
+Concretely spoken, for dynamics you have to write a performer
+(Dynamics_performer), that will take the input requests. If I
+understand correctly, every MIDI note played must have its dynamic
+strength set separately. That means the the Dynamics_performer must
+set the strength of every Audio_note it finds. This means that one
+has to modify existing Audio items. The best way of doing this is
+with a broadcast/acknowledge process.
+
+So the best way of handling this, is
+
+ 1 supporting dynamic settings in Audio_note
+
+ 2 Write a Dynamics_performer that will modify
+ any notes it finds to set appropriate strengths.
+
+I'd say that the work involved is not hard, but you have to be fluent
+with C++ and need some insight into the working of Notation Contexts
+and friends. I guess I could do it in a day or so, but if you are not
+so fluent with the inner workings of LilyPond, it could take you some
+more time (A few more days?).
+
+Please note, that I am *not* going to code this myself: my days are
+valuable, and I think I have more interesting things to do than fixing
+the MIDI output (I don't even have a soundcard). But I *do* want to help
+you or other people with implementing this, so if you need help, don't
+hesitate to ask.
