Ott is a tool for writing definitions of programming languages and calculi

It takes as input a definition of a language syntax and semantics, in a concise and readable ASCII notation that is close to what one would write in informal mathematics. It generates LaTeX to build a typeset version of the definition, and Coq, HOL, and Isabelle versions of the definition. Additionally, it can be run as a filter, taking a LaTeX/Coq/Isabelle/HOL source file with embedded (symbolic) terms of the defined language, parsing them and replacing them by target-system terms.
