+WikiLink Extention for Python-Markdown
+======================================
+
+Converts CamelCase words to relative links.  Requires Python-Markdown 1.6+
+
+Basic usage:
+
+    >>> import markdown
+    >>> text = "Some text with a WikiLink."
+    >>> md = markdown.markdown(text, ['wikilink'])
+    >>> md
+    '\\n<p>Some text with a <a href="/WikiLink/" class="wikilink">WikiLink</a>.\\n</p>\\n\\n\\n'
+
+To define custom settings the simple way:
+
+    >>> md = markdown.markdown(text, 
+    ...     ['wikilink(base_url=/wiki/,end_url=.html,html_class=foo)']
+    ... )
+    >>> md
+    '\\n<p>Some text with a <a href="/wiki/WikiLink.html" class="foo">WikiLink</a>.\\n</p>\\n\\n\\n'
+    
+Custom settings the complex way:
+
+    >>> md = markdown.Markdown(text, 
+    ...     extensions = ['wikilink'], 
+    ...     extension_configs = {'wikilink': [
+    ...                                 ('base_url', 'http://example.com/'), 
+    ...                                 ('end_url', '.html'),
+    ...                                 ('html_class', '') ]},
+    ...     encoding='utf8',
+    ...     safe_mode = True)
+    >>> str(md)
+    '\\n<p>Some text with a <a href="http://example.com/WikiLink.html">WikiLink</a>.\\n</p>\\n\\n\\n'
+
+From the command line:
+
+    python markdown.py -x wikilink(base_url=http://example.com/,end_url=.html,html_class=foo) src.txt
