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

Cmdliner can be installed with opam:
opam install cmdliner
If you don't use opam consult the opam file for build
instructions.
The documentation can be consulted online or via odig doc bytesrw.
Questions are welcome but better asked on the OCaml forum than on the issue tracker.
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
