Haar Cascade OpenCV: [duplicate]

Question

I can't find any information about Data used for training Haar classifiers in OpenCV. I want to know what kind of, how many and how(manually or via program) these classifiers were generated.

You can find these classifier's xml files in ..OpenCV2.3.1\opencv\data\haarcascades.. directory. Thanks
