Subject: ocamlbuild is VERY nifty
I asked around before settling on a build system since I'm new to  
OCaml. I looked at OMake, OCamlMakefile and found them complex and  
confusing. Then William Neuman pointed me to ocamlbuild and Nicolas  
Pouillard helped me hook it up to external libraries via a plugin.

Deep into my first project I confirm that ocamlbuild is VERY nifty. I  
can automatically rebuild when any parts of my project change and  
then run my unit tests.

All I need to do is:

ocamlbuild test.byte --

*** my project ***

      189 easy.mli
      282 easy_lexer.mll
      420 easy_parser.mly
       17 myocamlbuild.ml
       14 parser_util.ml
       30 symtab.ml
        8 test.ml
      284 parser_test.ml
     1355 total

*** test.ml ***

open OUnit

let suite = "Morpher" >:::

let _ =
   run_test_tt_main suite

*** myocamlbuild.ml ***

open Ocamlbuild_plugin;;
open Command;;

let packages = "ounit" (* "pkg1,pkg2,..." *);;

let ocamlfind cmd =
S[A"ocamlfind"; A cmd; A"-package"; A packages];;

flag ["ocaml"; "link"] (A"-linkpkg");;

dispatch begin function
| After_options ->
      Options.ocamlc := ocamlfind "ocamlc";
      Options.ocamlopt := ocamlfind "ocamlopt";
| _ -> ()
