Cmdliner â Declarative definition of command line interfaces for OCaml ------------------------------------------------------------------------------- %%VERSION%% 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 syntax errors, help messages and UNIX man page generation. It supports programs with single or multiple commands and respects most of the [POSIX][1] and [GNU][2] conventions. Cmdliner has no dependencies and is distributed under the ISC license.

It can be consulted [online][doc] or via `odig doc cmdliner`. [doc]: http://erratique.ch/software/cmdliner/doc/Cmdliner ## Sample programs If you installed Cmdliner with `opam` sample programs are located in the directory `opam config var cmdliner:doc`. These programs define the command line of some classic programs. In the distribution sample programs are located in the `test` directory of the distribution. They can be built and run with: topkg build --tests true && topkg test
