It is indeed a lucky author who is given the opportunity to completely rewrite a book barely a year after its publication. Writing about software affords such
opportunities (especially if the original edition sold out), since the author is shooting
at a moving target.
I^TgX and ^v^S-I^TeX improved dramatically with the release of the new
standard LATeX (called 1^X2^) in June of 1994 and the revision of Aj^-WFeX
(version 1.2) in February of 1995. The change in Ajv\S-VFl^X is profound. LTeX2^
made it possible for Aj\y[S-JfT£X to join the IATeX world. One of the main points
of the present book is to make this clear. This book introduces IATeX as a tool
for mathematical typesetting, and treats Aj\/[S-Wi^X as a set of enhancements to
the standard I^TeX, to be used in conjunction with hundreds of other IATeX2^
enhancements.
