I would like to have syntax highlighting while perusing my configs - does anybody know of a good Cisco IOS syntax highlighting bundle for TextMate or Sublime Text?

Edited (2015-09-21) to add:

GitHub Atom Editor has a Cisco IOS syntax highlighter in their built in "packages" repo and it is easy to install. I think that Sublime Text is a better editor, but if you are not already invested in ST, I recommend giving Atom a look.
