+synopsis: "Executable code blocks inside markdown files"
+description: """
+`ocaml-mdx` allows to execute code blocks inside markdown files.
+There are (currently) two sub-commands, corresponding
+to two modes of operations: pre-processing (`ocaml-mdx pp`)
+and tests (`ocaml-mdx test`).
+
+The pre-processor mode allows to mix documentation and code,
+and to practice "literate programming" using markdown and OCaml.
+
+The test mode allows to ensure that shell scripts and OCaml fragments
+in the documentation always stays up-to-date."""
