http://twistedmatrix.com/documents/10.1.0/web/howto/resource-templates.html includes some Quixote template markup. It's colorized, because Quixote is just Python.
But, eg, http://buildbot.twistedmatrix.com/builds/sphinx-html-15665/projects/web/howto/resource-templates.html does not have the markup colorized. I suppose this is because Sphinx doesn't recognize the .rtl extension? But apparently this could be fixed by including a "language" directive on the "literalinclude" directive. This makes sense anyway, because the Lore markup says "py-listing" - explicitly denoting it is Python.
