 \section{Introduction}
 The base frame and main idea of this document was taken from the article \textit{A brief history of \TeX,~volume~II} by Arthur Reutenauer in the proceedings of \textsf{EuroBacho\TeX 2007} and his talk there (see~references on page~\pageref{sec:refs}). Additional information is taken from original documentations and some review articles. For old, historic information, the \textsf{historic~archive} maintained by Ulrik Vieth and hosted on \url{ftp.tug.org} (see~refs) was very useful, especially in the reconstruction of \LaTeX\ versions. Many thanks for that great archive!

 \begin{description}
 \item[evince] Shows the document correct and complete. Tested using Linux.
 
 \item[Acrobat Reader] will show all the information but might hide some text of very long tooltips (at least that's the case on my machine). Also, it draws annoying green boxes around the tooltips which do not belong there.
