[Wonder-disc] Resource substitution property

[Ramsey G. <rg...@sm...>]

I could be mistaken, but isn't there a property that can be used to substitute resources for different files? For instance, if I have a resource in my app called main.css then in Properties.dev I could specify 

er.something.something.app.main.css=devmain.css

To substitute the devmain.css in for the main.css.

I've dug around a bit but not having any luck finding it. Maybe it just doesn't exist.
