Sublime Text 2: Setting file syntax inside the file itself (as Vim modelines)

There is a Modelines plugin for Sublime Text: https://github.com/SublimeText/Modelines

To do this for every file with a specific extension, with a file open go to menu View, Syntax, Open all with current extension as... and set your preference there.

It doesn't seem to be possible natively to set it per file or project, but propably you should take a look at this package: https://github.com/phillipkoebbe/DetectSyntax
