title: Syntax highlight Ruby code in RDoc file?
body: <p>I am documenting a Ruby library I am writing. In my README.rdoc file, I am including an example of the usage with some demo Ruby code.</p>
  
  <p>However, the resulting HTML documentation does not show the Ruby code with syntax highlighting, merely as a block of code.</p>
  
  <p>When I look at the source of e.g. <a href="http://rdoc.rubyforge.org/README_rdoc.html" rel="nofollow">http://rdoc.rubyforge.org/README_rdoc.html</a>, all I see is a piece of Ruby code, just like I included in my README.rdoc. Is there a special option to pass to the rdoc command?</p>
