How does one practice to develop super-mundane powers through meditation?

I have heard rumors of this happening and am curious if there is anything (especially textually according to the canon) on what practices may lead to this as i would like to see for myself if it is true or not. Please include references. An example being ESP or other psychic phenomena. Yes i know it is beside the point of practice and telling me that is not an answer to my question. Neither is the cop-out of "inappropriate question" so please refrain from posting such opinions!
