+Node environments
+-----------------
+At least Salt and Puppet support the notion of "environments", but the Salt
+adapter just puts everything into the "base" environment at the moment.
+
+Part of the reason that multiple environments aren't (yet) supported is

+a use-case, then please help me understand it and let's figure out a good way
+to introduce this concept into |reclass|.
