Sorry if I was unclear: that is the version that LaTeX complains about
with "missing \begin{document}". The complete code is:

\documentclass{article}

\usepackage{pdfpages}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \includescore{PossibleExtension}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Read in the TOC entries for a PDF file from the corresponding .toc file.
% This requires some heave latex tweaking, since reading in things from 
a file
% and inserting it into the arguments of a macro is not (easily) possible

% Solution by Patrick Fimml on #latex on April 18, 2009:
% \readfile{filename}{\variable}
% reads in the contents of the file into \variable (undefined if file
% doesn't exist)
\newread\readfile@f
\def\readfile@line#1{%
{\catcode`\^^M=10\global\read\readfile@f to \readfile@tmp}%
\edef\do{\noexpand\g@addto@macro{\noexpand#1}{\readfile@tmp}}\do%
\ifeof\readfile@f\else%
\readfile@line{#1}%
\fi%
}
\def\readfile#1#2{%
\openin\readfile@f=#1 %
\ifeof\readfile@f%
\typeout{No TOC file #1 available!}%
\else%
\gdef#2{}%
\readfile@line{#2}%
\fi
\closein\readfile@f%
}%

\newcommand{\includescore}[1]{
\def\oly@fname{\oly@basename\@ifmtarg{#1}{}{_#1}}
\let\oly@addtotoc\undefined
\readfile{\oly@xxxxxxxxx}{\oly@addtotoc}
\ifx\oly@addtotoc\undefined
\includepdf[pages=-]{\oly@fname}
\else
\edef\includeit{\noexpand\includepdf[pages=-,addtotoc={\oly@addtotoc}]
{\oly@fname}}\includeit
\fi
}

\begin{document}

\includescore{toc}

\end{document}


Thanks,
Jean
