-Features you cannot find in the doco as working, should be mentioned here.
-
-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.

- 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.

- *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...)
-
-

-3RD PARTY BUGS:
-
- * redhat (v?) graphical install bomb-out?
-
- * egcs-1.03 ice: stem.cc:327; should localize bug (mine's still 10K)
-
- * gcc 2.8.1: see ice and RESIZE_ICE
-
- * xdvi: PS in magnifying glass.
-
- * GNU patch 2.1: hardcoded limit of 1024 to the linelength
-
- * GNU diff 2.7: diff -rN does not see a new directory with empty file
-
- * GNU patch 2.1: <must find simple example> if patch chokes on a
- hunk, or on allegedly unsorted hunks in a diff, it may stop
- without a trace of failure (create .rej file, print error or
- dump core) and just ignore any further diffs.
-
- * glibc 2.0:
-
- f = fopen ("/dev/null", "r")
- assert (feof (f))
-
