Coda and Markdown?

[eluser]kilishan[/eluser]
I know we've got quite a few on these boards that use Coda, so I'm hoping you can help me. I've looked for a few days, now, and haven't had any luck finding a syntax file for Markdown that will work with Coda. I don't need conversion to html or anything like that, just to be able to have syntax highlighting.

Has anyone seen a beast like this out in the wild?

Thanks!
