+      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.
