 102      "The Lout document formatting system reads a high-level description of
 103 a document similar in style to LaTeX and produces a PostScript or plain text
 104 output file.
 105
 106 Lout offers an unprecedented range of advanced features, including optimal
 107 paragraph and page breaking, automatic hyphenation, PostScript EPS file
 108 inclusion and generation, equation formatting, tables, diagrams, rotation and
 109 scaling, sorted indexes, bibliographic databases, running headers and
 110 odd-even pages, automatic cross referencing, multilingual documents including
 111 hyphenation (most European languages are supported), formatting of computer
 112 programs, and much more, all ready to use.  Furthermore, Lout is easily
 113 extended with definitions which are very much easier to write than troff of
 114 TeX macros because Lout is a high-level, purely functional language, the
 115 outcome of an eight-year research project that went back to the
 116 beginning.")
