Writing out a table of contents to a file

[Reinhold Kainhofer]

I recently discovered that for full scores, it's easiest to write things like 
the preface in Latex and then merge together the PDFs. I discovered the 
pdfpages LaTeX package, which allows you to include whole PDF files page-wise, 
so I have one LaTeX document where I simply include the whole ~100 pages PDF 
produced by LilyPond. However, to automate the table of contents, I'd need 
some page information about where LilyPond places new pieces. 


Basically, for each headline, I add a TOC entry using 
#(toplevel-music-handler parser (add-toc-item! 'tocItemMarkup piecename))

in Lilypond, which adds the piece to the TOC. The TOC can then be printed in 
lilypond via:
\markuplines \table-of-contents 


However, I would rather get the page information into latex's TOC instead and 
for this I need to write out the TOC entries to a separate file, preferrably 
in the form 
    page-number, "section", 1, title, toc-label
for each entry (since the addtotoc argument for the includepdf latex command 
expects exactly such a list).

Now, it seems that I am unable to find a proper place where I have access to 
the TOC entries list with the page numbers properly determined and 
available...

Can anyone help me?

Cheers,
Reinhold
