 111 "The Lout document formatting system reads a high-level description of
 112 a document similar in style to LaTeX and produces a PostScript or plain text
 113 output file.
 114
 115 Lout offers an unprecedented range of advanced features, including optimal
 116 paragraph and page breaking, automatic hyphenation, PostScript EPS file
 117 inclusion and generation, equation formatting, tables, diagrams, rotation and
 118 scaling, sorted indexes, bibliographic databases, running headers and
 119 odd-even pages, automatic cross referencing, multilingual documents including
 120 hyphenation (most European languages are supported), formatting of computer
 121 programs, and much more, all ready to use.  Furthermore, Lout is easily
 122 extended with definitions which are very much easier to write than troff of
 123 TeX macros because Lout is a high-level, purely functional language, the
 124 outcome of an eight-year research project that went back to the
 125 beginning.")
