"""
Generic wiki markup PreFormatter 2002-11-18, for pyblosxom
CHANGE wikibaseurl to point to your wiki, & wikinamepattern to yours
Bug reports, comments, presents, etc. to John Abbe at [email protected]
ToDo: Lists; code/<pre>; InterWiki links; other wikinamepatterns

You can configure this as your default preformatter by configuring it in your
L{config} file as follows::

    py['parser'] = 'genericwiki'

or in your blosxom entries, place a C{#parser wiki} line after the title of
your blog::

    My Little Blog Entry
    #parser genericwiki
    This is a text in '''wiki''' format

This preformatter also supports WikiWirds, you need to point out where your
Wiki site is. This is configured with a new variable in your config.py file,
'genericwiki_baseurl'::

    py['genericwiki_baseurl'] = 'http://www.google.com/search?q='

The above example would expand 'WikiWord' to
http://www.google.com/search?q=WikiWord
