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