+Lout offers an unprecedented range of advanced features, including optimal
+paragraph and page breaking, automatic hyphenation, PostScript EPS file
+inclusion and generation, equation formatting, tables, diagrams, rotation and
+scaling, sorted indexes, bibliographic databases, running headers and
+odd-even pages, automatic cross referencing, multilingual documents including
+hyphenation (most European languages are supported), formatting of computer
+programs, and much more, all ready to use.  Furthermore, Lout is easily
+extended with definitions which are very much easier to write than troff of
+TeX macros because Lout is a high-level, purely functional language, the
+outcome of an eight-year research project that went back to the
+beginning.")
