explanations about playerview

[smacksoup]

Could someone kindly explain the readings for playerview? i dont have the program (well... have not began using yet) and would like to peruse the forums slightly more informed. if no one wants to elaborate, could he/she at least point me in the direction of a link? for example, what does vpip mean? im guessing pfr is preflop raise, but what about the scale/range of the numbers? probably a link would be best...
