-Sample Documentation
-====================
-
-Let's put something in the Sybil document's namespace:
-
-.. invisible-code-block: python
-
-  remember_me = b'see how namespaces work?'
-
-Suppose we define a function, convoluted and pointless but shows stuff nicely:
-
-.. code-block:: python
-
-  import sys
-
-  def prefix_and_print(message):
-      print('prefix:', message.decode('ascii'))
-
-Now we can use a doctest REPL to show it in action:
-
->>> prefix_and_print(remember_me)
-prefix: see how namespaces work?
-
-The namespace carries across from example to example, no matter what parser:
-
->>> remember_me
-b'see how namespaces work?'
