This readme describes the Robotlegs codebase. For usage and a general overview see the root readme file.
The best way to start learning the Robotlegs 2 codebase is to have a look at the MVCSBundle in src/robotlegs/bender/bundles/mvcs.
This bundle installs a number of extensions into your context. By reading the source for these extensions you can get a good overview of how everything ties together.
