I tried to copy from the Piano-centered dynamics template and it's
Dynamics context, which seems to be similar. I ended up with the
attached output, which looks quite okay.

However, during compilation Lily complains /a lot/ about the direction
property of RehearsalMark, MetronomeMark and TextSpanner:
        "Programmierfehler: [programming error:] direction unknown, but
aligned-side wanted"
and later
        "Ein Objekt außerhalb der Notenzeile sollte eine Richtung haben,
Vorgabe ist »nach oben«"
        [An object outside of the staff should have a direction, default is UP.]

What's up with this?


And how can I convince Lilypond of telling me errors in English? (This
is Mac OS X Leopard, from the bash. Tried LANG=C and LANG=en_US without
any success...)
