EULA

An EULA (End User License Agreement) is an agreement between the maker of a product and its end users. It is a binding agreement that if broken, voids the copy of the software owned by the user who voids the agreement. Nearly all proprietary software comes with an EULA that must be agreed to, such as Game Maker. The Game Maker EULA, like all EULAs, allows the distributing company to sue anyone who violates the agreement, just as Yoyo Games can sue the makers of decompliers.
