Some text with a [[WikiLink]].

A link with [[ white space and_underscores ]] and a empty [[ ]] one.

Another with [[double  spaces]] and [[double__underscores]] and 
one that [[has _emphasis_ inside]] and one [[with_multiple_underscores]] 
and one that is _[[emphasised]]_.

And a <a href="http://example.com/RealLink">RealLink</a>.

<http://example.com/And_A_AutoLink>

And a [MarkdownLink](/MarkdownLink/ "A MarkdownLink") for
completeness.
