I whipped up a wiki plugin that parses Nginx configuration examples and automatically links directives to their documentation. This should make it *much* easier to understand examples in our cookbook. Here's an example of the plugin in action:

http://wiki.codemongers.com/NginxFullExample2

To use the plugin, just add a shebang line to the top of examples, like this:

{{{#!nginx user www www; ... }}}

And it'll add links as appropriate. Cool, eh? Try it out by posting a tricky snippet from your config.

Let me know if you find any bugs or want to see the plugin source.
