The followings are required for building an ocaml parser using Planck
* pa_monad_custom -- from http://bitbucket.org/camlspotter/pa_monad_custom/
-* ocaml 3.12.0 source code tree, compiled, and its toplevel directory is symlinked as `ocaml' in this directory.
+* ocaml 3.12.0 source code tree, compiled, and its toplevel directory is symlinked as `ocaml/ocaml' in this directory. I mean, cat ocaml/ocaml/VERSION must show you a text "3.12.1...".
* (optional) lablgtk-2.14.2 source code for test parsing of oo codes. Its toplevel directory must be symlinked as `lablgtk-2.14.2' in this directory.
If you are not interesting in preparing these things for the ocaml parser, edit around the last line of OMakefile.
