I'm somewhat experienced with OMake for small projects, so I'll try to
help with that.  You have lots of options, depending on if you want a
single OMakefile or one in each subdirectory, whether or not you're
using lexers and parsers, how modular you want things to be, and so
on.  To give you some idea, a quick single-file OMakefile like this in
the root directory would probably work.

.PHONY all test

   FILES = foo bar bat baz
   OCamlProgram(some-target, $(FILES))
   all: some-target

targetExe = $(file src/some-target$(EXE))
   test1: $(targetExe)
      $(targetExe) ./test1-input > ./test1-output

   test: test1


If you want an OMakefile in each subdirectory, just cut the bodies of
the .SUBDIRS blocks and put them into the corresponding OMakefile's,
then use a single .SUBDIRS line like this:
.SUBDIRS src test

I'm sure there are others on this list with more OMake experience, so
if I've got something wrong please speak up!
