NAME
dune - composable build system for OCaml
SYNOPSIS
dune build [--watch]

dune exec NAME
dune utop [DIR]
dune install
dune init project NAME [PATH] [--libs=l1,l2 --ppx=p1,p2
--inline-tests]
DESCRIPTION
Dune is a build system designed for OCaml projects only. It focuses on
providing the user with a consistent experience and takes care of most
of the low-level details of OCaml compilation. All you have to do is
provide a description of your project and Dune will do the rest.
The scheme it implements is inspired from the one used inside Jane
Street and adapted to the open source world. It has matured over a
long time and is used daily by hundreds of developers, which means
that it is highly tested and productive.
