Hey Tapani

Yes, makefile is a good way to go.
I started using it in the last weeks and I think it's very very useful 
with LilyPond. I've been wanting to try to improve the doc about 
Makefile but didn't find the time to study it a bit more and try a 
patch.

Basically you'll have to do something like this (replace "[TAB] " with 
a real TAB character):

# Rule to compile any .ly file to PDF and MIDI
# The pattern is "output: input". I'll use % (same as * in bash), to 
catch all files ending with...
# $< is the input file
#
%.pdf, %.midi: %.ly
[TAB] lilypond $<

# Rule to build a lilypond-book file
mybook.pdf: mybook.lytex
[TAB] lilypond-book OPTIONS... $<

# Targets
book: mybook.pdf

clean:
[TAB] rm *.pdf *.midi
