 \section{Introduction}
-The base frame and main idea of this document was taken from the article \textsf{A brief history of \TeX,~volume~II} by Arthur Reutenauer in the proceedings of \textsf{EuroBacho\TeX 2007} and his talk there (see references). Additional information is taken from original documentations (see references on page \pageref{sec:refs}) 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. Many thanks for that great archive!
