An Example for an Elementary Wiki Structure
===========================================
  >>> from cybertools.wiki.base.wiki import WikiManager, Wiki
We create a wiki manager with one wiki that in turn contains a simple
start page.
  >>> manager = WikiManager()
  >>> wiki = manager.addWiki(Wiki('demo_wiki'))
  >>> startPage = wiki.createPage('start_page')
We format the content of the start page using the restructured text format.
  >>> startPage.text = '''
  ... **Welcome to the Demo Wiki**
  ... '''
As we have not yet registered any formatting plugins rendering the page
returns it content unchanged.
  >>> tree = startPage.parse()
  >>> print startPage.render()
  <p><strong>Welcome to the Demo Wiki</strong></p>
**Welcome to the Demo Wiki**
A Very Basic Wiki Format
========================
We first set up a format (a utility) and create a format instance
from it. The instance needs a wiki page as its context - to simplify
things during testing we just use a bare object.
  >>> from cybertools.wiki.base.format import BasicFormat
  >>> format = BasicFormat()
  >>> page = object()
  >>> instance = format.getInstance(page)
Now we enter some simple text and request the format instance to
unmarshall it, i.e. to convert it from the editable to the internal
representation.
  >>> input = ('This is text with a [[Wiki Link]].\n\n'
  ...          'It also contains a second line.')
  >>> instance.unmarshall(input)
  'This is text with a [[${l0000001}]].\n\nIt also contains a second line.'
