 will have an ~id~ attribute with that name in the HTML export. This
 enables one to create links to these elements in other places, e.g.,
 ~<a href="#name">text</a>~.

+You may want to add ~.listing-number { display: none; }~ to the CSS
+used.

 The ~-n~ option to ~SRC~ and ~EXAMPLE~ blocks can now take a numeric
 argument to specify the staring line number for the source or example
