Lout is a document formatting system similar to LaTeX. The system reads a high-level description of a document similar in style to LaTeX and produces a PostScript file which can be printed on most laser printers and graphic display devices. Plain text and PDF (starting from version 3.12) output are also available. Furthermore, Lout is easily extended with definitions which are easier to write than troff or TeX macros because Lout is a high-level language. Lout offers an unprecedented range of advanced features, including:

  • optimal paragraph 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, including Russian)
  • formatting of C, C++, Java, Eiffel, and other programs

  • User's guide (PS) (PDF)
