=== Horizontal Rules ===
You can insert a horizontal rule across the page by typing four or more dashes.  The number of dashes in a horizontal rule markup determines how thick it is, up to a limit of 10.

For more information on the possible markup, see HelpOnEditing. 

==== Example ====
<pre><nowiki>
