PRINTING HISTORY • First Edition: Printed in June of 2000. Plain-ASCII illustrations for universal computer readability. • Second Edition: Printed in September of 2000. Illustrations reworked in standard graphic (eps and jpeg) format. Source files translated to Texinfo format for easy online and printed publication. • Third Edition: Equations and tables reworked as graphic images rather than plain-ASCII text. • Fourth Edition: Printed in November 2001. Source files translated to SubML format. SubML is a simple markup language designed to easily convert to other markups like A LTEX, HTML, or DocBook using nothing but search-and-replace substitutions. • Fifth Edition: Printed in November 2002. New sections added, and error corrections made, since the fourth edition. • Sixth Edition: Printed in June 2006. Added CH 13, sections added, and error corrections made, figure numbering and captions added, since the fifth edition.
