Be warned that sometimes lilypond-book has hash collisions in the
filename, which can lead to weird compile errors when one process
finished dealing with aa/lily-aaaa.ps (and thus deletes it), while
another process has finished generating aa/lily-aaaa.ps but hasn't
started running ps2pdf yet, and thus doesn't find the file that it
just wrote.

If you use that command and something breaks, run "make check", wait
10 seconds or so, then cancel that, and then re-run the fancier
command.
