When I run musicxml2ly on a music XML file containing breves e.g.
<duration>16</duration>
<voice>1</voice>
<type>breve</type>
it crashes with the diagnostic as follows:
Traceback (most recent call last):
File "C:\Program Files\LilyPond\usr\bin\musicxml2ly.py", line 675, in ?

File "C:\Program Files\LilyPond\usr\bin\musicxml2ly.py", line 672, in main

ValueError: negative shift count
Whilst Lilypond sems to know about breves and longas (though, sady not maximas)
I suspect that musicxml2ly does not. When I patched out the breves it converted
the file but without lyrics - should it handle them?.
Sadly, runnng under Windows XP Lilypond 2.10.33 fails to typeset the result,
without comment. Is there a way to find out what its problem is - the -V option
or --verpose seem to have no effect
