ocamlbuild - The OCaml project compilation tool

ocamlbuild(1) orchestrates the compilation process of your OCaml project.  It is similar in  function  to
       make(1)  except that it is tailor-made to automatically compile most OCaml projects with very little user
       input.

       ocamlbuild should be invoked in the root of a clean project tree  (e.g.,  with  no  leftover  compilation
       files).  Given one or more targets to compile, it scans the required subdirectories to gather information
       about the various files present, running tools such as ocamldep(1) to extract dependency information, and
       gathering optional files that fine-tune its behaviour.  Target names are very significant.

ocamlbuild  uses  a  set  of  target naming conventions to select the kind of objects to produce.  Target
       names are of the form base.extension where base is usually the name of the underlying  OCaml  module  and
       extension  denotes  the  kind  of  object  to  produce from that file -- a byte code executable, a native
       executable, documentation...  Of course extensions such as  .cmo,.cma,.cmi...   map  to  their  usual
       counterparts.  Here is a list of the most important ocamlbuild-specific extensions:

       .native             Native code executable

       .byte               Byte code executable

       .inferred.mli       Interface inferred with ocamlc-i
