+"""Priority based json library imports.
+
+Always serializes to bytes instead of unicode for zeromq compatibility
+on Python 2 and 3.
+
+Use ``jsonapi.loads()`` and ``jsonapi.dumps()`` for guaranteed symmetry.
+
+Priority: ``simplejson`` > ``jsonlib2`` > stdlib ``json``
+
+``jsonapi.loads/dumps`` provide kwarg-compatibility with stdlib json.
+
+``jsonapi.jsonmod`` will be the module of the actual underlying implementation.
