+  (description
+   "Logs provides a logging infrastructure for OCaml.  Logging is performed on
+sources whose reporting level can be set independently.  Log message report is
+decoupled from logging and is handled by a reporter.  A few optional log
+reporters are distributed with the base library and the API easily allows to
+implement your own. `Logs` has no dependencies.  The optional `Logs_fmt`
+reporter on OCaml formatters depends on [Fmt][fmt].  The optional `Logs_browser`
+reporter that reports to the web browser console depends on [js_of_ocaml][jsoo].
+ The optional `Logs_cli` library that provides command line support for
+controlling Logs depends on [`Cmdliner`][cmdliner].  The optional `Logs_lwt`
+library that provides Lwt logging functions depends on [`Lwt`][lwt] Logs and its
+reporters are distributed under the ISC license. [fmt]:
