--001a11404268b1a100054ae7e030 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Yes, having a config.ml file with the configuration options you want to share would make sense. Note if you want to refer to the variable x in config.ml, you can either do "open Config" and then use "x", or just use "Config.x". The latter tends to be preferred as it is more precise and does not clutter the global environment of available names. If you find yourself using Config a lot in a part of the code, you can always to "let open Config in ..." locally to restrict the scope open the environment-changing "open" command.
