+Meta Data Extension for Python-Markdown
+=======================================
+
+This extension adds Meta Data handling to markdown.
+
+Basic Usage:
+
+    >>> import markdown
+    >>> text = '''Title: A Test Doc.
+    ... Author: Waylan Limberg
+    ...         John Doe
+    ... Blank_Data:
+    ...
+    ... The body. This is paragraph one.
+    ... '''
+    >>> md = markdown.Markdown(['meta'])
+    >>> md.convert(text)
+    u'<p>The body. This is paragraph one.</p>'
+    >>> md.Meta
+    {u'blank_data': [u''], u'author': [u'Waylan Limberg', u'John Doe'], u'title': [u'A Test Doc.']}
+
+Make sure text without Meta Data still works (markdown < 1.6b returns a <p>).
+
+    >>> text = '    Some Code - not extra lines of meta data.'
+    >>> md = markdown.Markdown(['meta'])
+    >>> md.convert(text)
+    u'<pre><code>Some Code - not extra lines of meta data.\\n</code></pre>'
+    >>> md.Meta
+    {}
