This is the core library for Lithium Bootstrap. It holds all of the functionality and core assets. Most likely you will be using the li3_bootstrap repository for a new project and that includes this library automatically.
However, if you like, you can clone this to your project. Keep in mind that you may have some conflicting routes. Also keep in mind that there may be other configuration conflicts between your application and Lithium Bootstrap and also other libraries that have been built for use with Lithium Bootstrap.
This library relies on li3_flash_messages: https://github.com/michaelhue/li3_flash_message
Of course, it also requires the Lithium framework: https://github.com/UnionOfRAD/lithium
