Fine with me! However, lilypond-book currently fails in several ways
in Windows.

- Problem 1: The python package is broken, so lilypond-book fails with:
AttributeError: 'module' object has no attribute 'pipe'
 Workaround: Install the native Python package and call lilypond-book
 using
"C:\Program Files\Python2.4\python.exe" "C:\Program 
Files\LilyPond\usr\bin\lilypond-book.py" ...

- Problem 2: It seems that you can't use single quotes to quote
 arguments in Windows. The printouts from lilypond-book -V --pdf ...  include:

 Double quotes seem to work much better and shouldn't cause any 
problems in  Linux and OSX(?), therefore I proposed a patch in  
http://lists.gnu.org/archive/html/bug-lilypond/2006-03/msg00182.html
 but it was never accepted.

Problem 3: Even with that patch, lilypond-book --pdf ... fails with

 and if I run with --verbose, the warning: can't find file: `'
 appears in the following context:

----------------------------------------------------------------

 However, all lily-*.ly files are processed correctly so if I just
 rerun lilypond-book once more, it will succeed and it works well
 to produce a PDF using pdflatex from MikTeX.
