The Free On-line Dictionary of Computing (30 December 2018):

Lout

   Lout is a batch text formatting system and an embedded
   language by Jeffrey H. Kingston .  The
   language is procedural, with Scribe-like syntax.

   Lout features equation formatting, tables, diagrams, rotation
   and scaling, sorted indexes, bibliographic databases, running
   headers and odd-even pages and automatic cross-referencing.
   Lout is easily extended with definitions which are very much
   easier to write than troff of TeX macros because Lout is
   a high-level language, the outcome of an eight-year research
   project that went back to the beginning.

   Version 2.05 includes a translator from Lout to PostScript
   and documentation. and runs under Unix and on the Amiga.
