No; just take the simplest possible .lytex file (such as the
template from the docs).  Run
  lilypond-book --pdf --out=/tmp foo.lytex
  lilypond-book --pdf --out=/tmp foo.lytex

Both times, it compiles all the lilypond snippets and creates a
new foo.tex in /tmp/.  I think this is because lilypnod-book looks
for a foo.tex in the same directory, instead of looking in the
output directory.

If you add -I=/tmp/  then lilypond-book won't recompile all the
snippets on the second (idential) run.  This works fine for me,
but since John's familiar with lilypnod-book, python, and was
offering, I figured it was worth mentioning.
