Well, the links you give just prove my point that `/opt/lilypond'
would be a better choice than `/usr/local/lilypond' – I don't want
mpkg to install into `/usr/local/bin', `/usr/local/lib', etc.
Instead, we have a complete bundle, with a separate directory
hierarchy.

Normally, the directory structure below `/usr/local' mimics `/usr'.
Having stuff like `/usr/local/texlive' is thus an exception, basically
violating FHS.  Not everyone likes it; see the thread starting at
