"""Remote API version 2 baserlib.library.
+ PUT or POST?
+ ============
+
+ According to RFC2616 the main difference between PUT and POST is that
+ POST can create new resources but PUT can only create the resource the
+ URI was pointing to on the PUT request.
+
+ To be in context of this module for instance creation POST on
+ /2/instances is legitim while PUT would be not, due to it does create a
+ new entity and not just replace /2/instances with it.
+
+ So when adding new methods, if they are operating on the URI entity itself,
+ PUT should be prefered over POST.
