General Public Licenses are designed to make sure that you have the freedom to
distributecopiesoffreesoftware(andchargeforthisserviceifyouwish),thatyou

usepiecesofitinnewfreeprograms;andthatyouknowyoucandothesethings.
Toprotectyourrights,weneedtomakerestrictionsthatforbidanyonetodeny
you these rights or to ask you to surrender the rights. These restrictions translate
tocertainresponsibilitiesforyouifyoudistributecopiesofthesoftware,orifyou
modify it.
Forexample,ifyoudistributecopiesofsuchaprogram,whethergratisorfora
fee, you must give the recipients all the rights that you have. You must make sure
thatthey,too,receiveorcangetthesourcecode.Andyoumust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,distributeand/ormodifythe
software.
Also,foreachauthor’sprotectionandours,wewanttomakecertainthateveryone
understandsthatthereisnowarrantyforthisfreesoftware.Ifthesoftwareis

Finally,anyfreeprogramisthreatenedconstantlybysoftwarepatents.Wewishto
avoidthedangerthatredistributorsofafreeprogramwillindividuallyobtainpatent
licenses,ineffectmakingtheprogramproprietary.Topreventthis,wehavemadeit
clear that any patent must be licensed for everyone’s free use or not licensed at all.
