Usage: add stub for info about shared \includes.

This is aimed at non-lilypond-distributed projects, such as
Dr. Chubb's articulate.ly (better MIDI sound).  Ideally we'd have
nothing in this section (because anything useful would be merged
with lilypond, possibly about being cleaned up a bit), but adding
info here is a useful stepping stone.
