See the asset pipeline for Ruby on Rails:
Or the equivalent in the Java Play! framework:
These kinds of frameworks are our "competition" so to speak since we are trying to build similar levels of functionality into KRAD.
At any rate, I would love to see KRAD having a similar level of capability as the Rails asset pipeline where it can automatically minify, etag, and fingerprint for you and the developer gets all of that for free without having to configure anything. I wonder if someone has already built something similar in Java that we could use?
