       ocamlbuild - The Objective Caml project compilation tool


       ocamlbuild  [  -Is  dir1,...  ] [ -libs lib1,...  ] [ -lflags flag1,...  ] [ -pp flags ] [
       -tags tag1,...  ] [ -j  parallel-jobs ] target.native [ -- arg1 arg2 ...  ]

       (same options)


       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

       .docdir/index.html  HTML documentation generated with ocamldoc


       The following command-line options are recognized by ocamlbuild(1).
