Thank you for the comment! Yes, I think there was mild criticism of
the flags when I initially mentioned Gonville on this list; I
regrettably haven't got round to looking at them again, but I still
mean to...

Meanwhile, I've just had another go at making Lilypond (2.13.14)
work with Gonville, with a view to updating the Gonville web page to
supersede my current hacky installation instructions. I was able to
get most of the musical glyphs to appear in Gonville, but I haven't
worked out how to get the ASCII parts of the font - the time
signature and dynamics letters - to switch over as seamlessly.

I attach my test input files. 'test.ly' is the starting point,
before I do anything to the font configuration; 'testg.ly' is
transformed as specified in input/regression/gonville.ly (and I also
followed the download instructions also given in that file), which
has the effect of substituting Gonville for the Feta glyphs in the
music itself, but the time signature and dynamics are still in Feta.

The best I've managed to do for those (in testg2.ly) is to add

      \override Staff.TimeSignature #'font-name = #"Gonville"
      \override Staff.TimeSignature #'font-size = #5
      \override DynamicText #'font-name = #"Gonville"
      \override DynamicText #'font-size = #5

in the staff section; that generates a PS output file with Gonville
everywhere I expect it, but only at _approximately_ the right size,
and my guess is that it's hopelessly wrong as a general mechanism
since it won't automatically adapt if the staff size is
reconfigured. (Plus, of course, I apparently have to specify it
separately for every staff if I do it this way.)

Is there a more sensible piece of configuration language I should be
using for this part of the job? I wasn't able to find anything in
the docs, I'm afraid.

Cheers,
Simon
