On my default install of FreeBSD-5.2 there is a
/usr/share/doc which does not contain any lilypond files or
subdirectories. There is also
/usr/local/share/lilypond/2.2.2 directory which contains
subdirectories or files of dvips, fonts, ls-R, ly, make, ps, python,
scm, tex, vim.
And then there is
/usr/local/share/doc/lilypond which contain these files AUTHORS.txt,
INSTALL.txt, NEWS.txt, README.txt.
Then there is /usr/local/info/lilypond and /usr/local/lib/lilypond and
/usr/local/share/examples all of which do not contain the docs.
Thats it.

Chip
