+==================
+Test viewlet order
+==================
+
+If one wants the viewlets rendered in a certain order it's possible
+to use the grok.order() directive.
+
+Set up a content object in the application root::
+
+  >>> root = getRootFolder()
+  >>> root['fred'] = Fred()
+
+Traverse to the view on the model object. We get the viewlets
+registered for the default layer, with the anybody permission::
+
+  >>> from zope.testbrowser.testing import Browser
+  >>> browser = Browser()
+  >>> browser.handleErrors = False
+  >>> browser.open("http://localhost/fred/@@orderview")
+  >>> print browser.contents
+  Gold
+  Bone
+  Fred
+  Cave
+  Wilma
+  Barney
+  <BLANKLINE>
