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modifiedby
someoneelseandpassedon,wewantitsrecipientstoknowthatwhattheyhaveisnotthe

reputations.
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.
