The question is, even if there was such a thing, would you know what to do with it?
Probably not. You would have to dig into caps, and interpret how things work. Then even if the source was adequately commented, you still can't copy from one cap to another.
On the other hand the forum is littered with a mountain of bits and pieces that are usually explained, and free to use, since nobody here is going to charge for an idea.
