i want to use Yahoobb pack http://github.com/xdite/yahoobb-pack/tree/master as a lib and integrate into a new rails project created by me, but this Yahoobb pack is a rails project, how to do? thanks...

sorry for my poor english

Just start with that project instead of creating your own. Then edit and modify to suit your needs. It's just a way for you to start out with some pre-written code.
