By contrast, the GNU GeneralPublic License is intended to guarantee your freedom to shareand change free software - to make sure the software is free forall its users. This General Public License applies to most ofthe Free Software Foundation's software and to any other programwhose authors commit to using it. (Some other Free SoftwareFoundation software is covered by the GNU Library General PublicLicense instead.) You can apply it to your programs, too.</P><P> When we speak of free software, we are referring to freedom, notprice. Our General Public Licenses are designed to make surethat you have the freedom to distribute copies of free software(and charge for this service if you wish), that you receivesource code or can get it if you want it, that you can changethe software or use pieces of it in new free programs; and thatyou know you can do these things.</P><P> To protect your rights, we need to make restrictions that forbidanyone to deny you these rights or to ask you to surrender therights. These restrictions translate to certain responsibilitiesfor you if you distribute copies of the software, or if youmodify it.</P><P> For example, if you distribute copies of such a program, whethergratis or for a fee, you must give the recipients all the rightsthat you have. You must make sure that they, too, receive or canget the source code. And you must show them these terms so theyknow their rights.</P><P> We protect your rights with two steps:<P></P><OLTYPE="1"><LI><P> copyright the software, and</P></LI><LI><P> offer you this license which gives you legal permission tocopy, distribute and/or modify the software.</P></LI></OL></P><P> Also, for each author's protection and ours, we want to makecertain that everyone understands that there is no warranty forthis free software. If the software is modified by someone elseand passed on, we want its recipients to know that what theyhave is not the original, so that any problems introduced byothers will not reflect on the original authors' reputations.</P><P> Finally, any free program is threatened constantly by softwarepatents. We wish to avoid the danger that redistributors of afree program will individually obtain patent licenses, in effectmaking the program proprietary. To prevent this, we have made itclear that any patent must be licensed for everyone's free useor not licensed at all.</P><P> The precise terms and conditions for copying, distribution andmodification follow.</P></DIV></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="c1968.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="book1.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="gpl-terms.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Dithering</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"> </TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</TD></TR></TABLE></DIV></BODY></HTML>
