+description: """
+Findlib is a library manager for OCaml. It provides a convention how
+to store libraries, and a file format ("META") to describe the
+properties of libraries. There is also a tool (ocamlfind) for
+interpreting the META files, so that it is very easy to use libraries
+in programs and scripts.
