CreeperFramework is what it says, a framework for Creeper-services, just like MediaCreeper. In fact, MediaCreeper is all CreeperFramework, as I use it as my pet-project for developing CreeperFramework. In the future I hope to release CreeperFramework as Open Source.
The framework consists of loadable parts, where the framework loads just the parts that is absolutely necessary and only them, to serve a request. The general idea is to keep it lean, clean and simple as possible. No code should be duplicated between classes.
Update 2014-08-08: The CreeperFramework will be reworked to be an API. Work on this is already under way. This will also shrink the code base as less code is needed on the back end of the framework.
