+"""A more liberal autolinker
+
+Inspired by Django's urlize function.
+
+Positive examples:
+
+>>> import markdown
+>>> md = markdown.Markdown(extensions=['urlize'])
+
+>>> md.convert('http://example.com/')
+u'<p><a href="http://example.com/">http://example.com/</a></p>'
+
+>>> md.convert('go to http://example.com')
+u'<p>go to <a href="http://example.com">http://example.com</a></p>'
+
+>>> md.convert('example.com')
+u'<p><a href="http://example.com">example.com</a></p>'
+
+>>> md.convert('example.net')
+u'<p><a href="http://example.net">example.net</a></p>'
+
+>>> md.convert('www.example.us')
+u'<p><a href="http://www.example.us">www.example.us</a></p>'

+>>> md.convert('(www.example.us/path/?name=val)')
+u'<p>(<a href="http://www.example.us/path/?name=val">www.example.us/path/?name=val</a>)</p>'
+
+>>> md.convert('go to <http://example.com> now!')
