%$Header$ \chapter{Acknowledgements} I am very grateful for all of the assistance I have received with this set of works (the book, the tool set, and supplemental materials). I would like to extend my gratitude to the following individuals and institutions. For assistance in procuring \LaTeXe{} (\emph{4allTex} Version 5), I am grateful to Mr. Erik Frambach, Mr. Gerard van Nes, and the Dutch \TeX{} User's Group. For assistance in learning how to use \LaTeX{} and \TeX{}, I am especially grateful to Mr. Tobias Oetiker\footnote{Author of \emph{The Not So Short Introduction To \LaTeXe{}}, which is available on the Web.}, who provided detailed e-mail answers to all of my questions. Mr. Oetiker also provided the source code for his document on the Web, and I was able to use this as a template to jump-start me in the direction of an aesthetically pleasing \LaTeX{} book. I am also grateful to the Dutch \TeX{} User's Group, the UK \TeX{} User's Group (UKTUG), and many helpful posters on the \texttt{comp.text.tex} newsgroup \cite{bibref:n:comptexttex} for support. For hosting this project (the book, the tool set, and all supporting materials), I am very grateful to \index{SourceForge}\emph{SourceForge} (\texttt{http://www.sourceforge.net})---coordinating and distributing this project simply would not have been possible without their support. At SourceForge, I am very grateful to Mr. Jacob Moorman for technical support and assistance on many, many occasions. I would like to acknowledge the contribution of \index{GNU}GNU (\texttt{http://www.gnu.org}), \index{Free Software Foundation (FSF)}The Free Software Foundation (\texttt{http://www.fsf.org}), and all of the open-source developers in the world who have produced many excellent and helpful products, including \LaTeX{} (used to write this book) and \index{Tcl}\emph{Tcl} (the basis for much of \emph{The ESRG Tool Set}). Finally, I would like to gratefully acknowledge the topic-specific contributions of the individuals who are acknowledged at the end of each chapter. \begin{figure}[b] \noindent\rule[-0.25in]{\textwidth}{1pt} \begin{tiny} \begin{verbatim} $HeadURL$ $Revision$ $Date$ $Author$ \end{verbatim} \end{tiny} \noindent\rule[0.25in]{\textwidth}{1pt} \end{figure} % %End of WORKACKS.TEX
