OCaml Library Managerhttp://projects.camlcity.org/projects/findlib.html
Findlib is a library manager for Objective Caml. 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.
Findlib is the de-facto standard for library management in OCaml.
