deny you these rights or to ask you to surrender the rights. Theserestrictions translate to certain responsibilities for you if you distributecopies of the software, or if you modify it.For example, if you distribute copies of such a program, whether gratis orfor a fee, you must give the recipients all the rights that you have. Youmust make sure that they, too, receive or can get the source code. And youmust show them these terms so they know their rights.We protect your rights with two steps: (1) copyright the software, and (2)offer you this license which gives you legal permission to copy, distributeand/or modify the software.Also, for each author's protection and ours, we want to make certain thateveryone understands that there is no warranty for this free software. Ifthe software is modified by someone else and passed on, we want itsrecipients to know that what they have is not the original, so that anyproblems introduced by others will not reflect on the original authors'reputations.Finally, any free program is threatened constantly by software patents. Wewish to avoid the danger that redistributors of a free program willindividually obtain patent licenses, in effect making the programproprietary. To prevent this, we have made it clear that any patent must belicensed for everyone's free use or not licensed at all.The precise terms and conditions for copying, distribution and modificationfollow.TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION0.
