Cmdliner provides a simple and compositional mechanism
to convert command line arguments to OCaml values and pass them to
your functions.

The library automatically handles command line completion, syntax
errors, help messages and UNIX man page generation. It supports
programs with single or multiple commands (like [git]) and respect
most of the
{{:http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap12.html}
POSIX} and
{{:http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html}
GNU} conventions.
