+\section{User documentation}
+
+This package provides a way to check if a document is being processed with \XeTeX. It may be loaded with
+
+\bigskip
+\begin{tabular}{l@{\quad}l}
+{|\usepackage{ifxetex}|} & for \LaTeX, or \\ 
+{|\input ifxetex.sty|} & for Plain \TeX.
+\end{tabular}
+\bigskip
+
+\noindent
+This defines the conditional \cmd\ifxetex\ that is used in the standard way:
+
+\bigskip
+|\ifxetex|\par
+\hspace{2em}\meta{material for \XeTeX}\par
+|\else|\par
+\hspace{2em}\meta{material not for \XeTeX}\par
+|\fi|
+\bigskip
+
+\noindent 
+Users of \LaTeX's \pkg{ifthen} package can also use it as |\boolean{xetex}|:
+
+\bigskip
+|\ifthenelse{ \boolean{xetex} }{|\texttt{\char`\%}\par
+\hspace{2em}\meta{material for \XeTeX}\par
+|}{|\texttt{\char`\%}\par
+\hspace{2em}\meta{material not for \XeTeX}\par
+|}|
+\bigskip
+
+\noindent
+Finally, the |\RequireXeTeX| command tests for \XeTeX\ use and
+throws an error if a different engine is being used. This is used
+for packages like \pkg{fontspec} that take advantage of \XeTeX's new
+features and cannot be used otherwise.
