Polygen is a program for generating random sentences according to a grammar definition, that is following custom syntactical and lexical rules.

formally, it is an interpreter of a language itself designed to define languages, where to interpret means executing a source program in real time and eventually outputting its result.

here a source program is a grammar definition, the execution consists in the exploration of such grammar by selecting a random path and the result is the sentence built on the way.

this package contains various grammar files suited for polygen.
