+     "@code{ocaml-mdx} allows to execute code blocks inside markdown files.
+There are (currently) two sub-commands, corresponding
+to two modes of operations: pre-processing (@code{ocaml-mdx pp})
+and tests (@code{ocaml-mdx test}]).
+
+The pre-processor mode allows to mix documentation and code,
+and to practice @dfn{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.
+
+@code{ocaml-mdx} is released as two binaries called @code{ocaml-mdx} and
+@code{mdx} which are the same, mdx being the deprecated name, kept for now for
+compatibility.")
