East west quantum leap how to use it with cubase 6???

I have a question, probably a stupid one, but how do I use EWQL (east west quantum leap) in cubase 6? I currently own cubase 6 (full version), and I have some EWQL packages, and I want to know how I can use them in cubase. Can I use EWQL just like HALionSE in cubase? and how do I “install” EWQL, so I can use EWQL in cubase 6?
thanks for answers!
