\def\AbstractText{%
Donald Knuth's \TeX\ is a text processing system with many powerful
and convenient features.  Its architecture and user interface are substantially
different from the {\it troff\/} family of programs with which most
\font\cmcsc=cmcsc10
{\cmcsc Unix$^{\rm TM}$} users are familiar.  An introduction to
the archi\TeX ture of Knuth's system is presented, with many references
to the corresponding features of {\it troff\/}.
This version corresponds to Version 1.1 of \TeX;  `\TeX' is a
Trademark of the American Mathematical Society.}
