+synopsis: "A tool for writing definitions of programming languages and calculi"
+description: """
+Ott 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 output:
+- a LaTeX source file that defines commands to build a typeset version of the definition;
+- a Coq version of the definition;
+- a HOL version of the definition;
+- an Isabelle/HOL version of the definition;
+- a Lem version of the definition;
+- an OCaml version of the syntax of the definition.
+Additionally, it can be run as a filter, taking a
+LaTeX/Coq/Isabelle/HOL/Lem/OCaml source file
+with embedded (symbolic) terms of the defined language, parsing them and
+replacing them by typeset terms.
