NAME

       ocamlbuild - The Objective Caml project compilation tool

SYNOPSIS

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

       (same options)

DESCRIPTION

       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.

TARGET NAMES

       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
