sourcehighlight is annoyingly slow, but it does support wiki directives
in comments. See [here](http://www.cs.unb.ca/~bremner/teaching/java_examples/snippet/ListMerge/)
for an example (tags).

+I think having the option to choose source code page types from the
+dropdown list is definitely a feature. This gives users an easy way
+to contribute programs (say `.pl` files) or code snippets (like, for
+example, the Elisp area of the EmacsWiki). Actually, would there any
+other way to create a `.pl` file without write access to the
+repository? --[[JasonBlevins]]
