* Scope bug

* Support all backends for multiple entry points

* Fix extensions

* Name the generated binaries appropriately

* Turn on module aliasing for top level dir for bucklescript engine

* Add merlin support back

* Merlin works with mutliple entry points

* Refactor

+# OCaml that provides autocompletion, jump-to-location, recoverable syntax
+# errors, type errors detection, etc., that your editor can use. To activate it,
+# one usually provides a .merlin file at the Path.the_root of a project, describing where
+# the sources and artifacts are. Since we dictated the project structure, we can

+# jump-to-location work correctly in conjunction with our build & namespacing
+# setup, when you jump into a third-party file.
