There is a small utility call ocamlify:
https://forge.ocamlcore.org/projects/ocamlify/
http://darcs.ocamlcore.org/repos/ocamlify/ocamlify/ (darcs repository)

You should look at ocaml-autobuild that use it extensively to include
files in the exec:
http://darcs.ocamlcore.org/repos/ocaml-autobuild/ocaml-autobuild/src/base/BaseDa\
ta.mlify

with the following rules in ocamlbuild:
let ocamlify = A"ocamlify";;

rule "ocamlify: %.mlify -> %.mlify.depends"
~prod:"%.mlify.depends"
~dep:"%.mlify"
begin
fun env _ ->
Cmd(S[ocamlify;
T(tags_of_pathname (env "%.mlify")++"ocamlify"++"depends");
A"--depends";
A"--output"; P(env "%.mlify.depends");
P(env "%.mlify");])
end
;;

rule "ocamlify: %.mlify & %.mlify.depends -> %.ml"
~prod:"%.ml"
~deps:["%.mlify"; "%.mlify.depends"]
begin
fun env build ->
depends_from_file
env
build
(env "%.mlify.depends");
Cmd(S[ocamlify; A"--output"; P(env "%.ml"); P(env "%.mlify")])
end
;;


This allow to create a .ml file containing the various file you want to
include as string or string list.

There is no release for now, as the project is tightly coupled with
ocaml-autobuild which is not yet released.
