    A binary executable.

library [OPTION]… NAME [PATH]
    An OCaml library.

project [OPTION]… NAME [PATH]
    A project is a predefined composition of components arranged in a standard directory structure. The kind of project initialized is determined by the value of the --kind flag and defaults to an executable project, composed of a library, an executable, and a test component.

test [OPTION]… NAME [PATH]

EXAMPLES

1.  Generate a project skeleton for an executable named `myproj' in a new directory named `myproj', depending on the bos library and using inline tests along with ppx_inline_test:

      dune init proj myproj --libs bos --ppx ppx_inline_test --inline-tests

2.  Configure an executable component named `myexe' in a dune file in the current directory:

      dune init exe myexe

3.  Configure a library component named `mylib' in a dune file in the ./src directory depending on the core and cmdliner libraries, the ppx_let and ppx_inline_test preprocessors, and declared as using inline tests:

      dune init lib mylib src --libs core,cmdliner --ppx ppx_let,ppx_inline_test --inline-tests

4.  Configure a test component named `mytest' in a dune file in the ./test directory that depends on `mylib':

      dune init test mytest test --libs mylib
