+''' This file is part of a plan to clean up the ckan.lib.helpers whilst
+keeping existing versions of ckan from breaking.
+
+
+When it is decided that we will make the template var cleanup
+permanent we will need to implement this using __all__ = [...] in
+lib.helpers itself.  Unused imports can also be removed at this time.
+
+yes, yes `from ... import ...` is the work of Satan but this is just a
+short term botch :)
