#! /usr/bin/python2.7 """Solitaire game, much like the one that comes with MS Windows. Limitations: - No cute graphical images for the playing cards faces or backs. - No scoring or timer. - No undo. - No option to turn 3 cards at a time. - No keyboard shortcuts. - Less fancy animation when you win. - The determination of which stack you drag to is more relaxed. Apology: I'm not much of a card player, so my terminology in these comments may at times be a little unusual. If you have suggestions, please let me know!
