+     "XeTeX is a TeX typesetting engine using Unicode and supporting modern font
+technologies such as OpenType, TrueType or Apple Advanced Typography (AAT),
+including OpenType mathematics fonts.  XeTeX supports many extensions that
+reflect its origins in linguistic research; it also supports micro-typography
+(as available in pdfTeX).  XeTeX was developed by the SIL (the first version
+was specifically developed for those studying linguistics, and using Macintosh
+computers).  XeTeX's immediate output is an extended variant of DVI format,
+which is ordinarily processed by a tightly bound processor (called
+@code{xdvipdfmx}), that produces PDF.")
