Description

Cmdliner allows the declarative definition of command line interfaces for OCaml.

It provides a simple and compositional mechanism to convert command line arguments to OCaml values and pass them to your functions. The module automatically handles command line completion, syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the POSIX and GNU conventions.

Cmdliner has no dependencies and is distributed under the ISC license.
