certainresponsibilitiesifyoudistributecopiesofthesoftware,orif
you modifyit: responsibilitiestorespectthefreedomofothers.

DevelopersthatusetheGNUGPLprotectyourrightswith two steps:
(1)assertcopyrightonthesoftware,and(2)offeryouthisLicense
givingyoulegalpermissiontocopy,distributeand/ormodifyit.

Forthedevelopers' and authors'protection,theGPLclearlyexplains
thatthereisnowarrantyforthisfreesoftware.Forbothusers' and
authors' sake, the GPL requires that modified versions be marked as
changed,sothattheirproblemswillnotbeattributederroneouslyto
authorsofpreviousversions.

Somedevicesaredesignedtodenyusersaccesstoinstallorrun
modifiedversionsofthesoftwareinsidethem,althoughthemanufacturer
candoso.Thisisfundamentallyincompatiblewiththeaimof
protectingusers' freedom to change the software. The systematic
patternofsuchabuseoccursintheareaofproductsforindividualsto
use,whichispreciselywhereitismostunacceptable.Therefore,we
havedesignedthisversionoftheGPLtoprohibitthepracticeforthose
products.Ifsuchproblemsarisesubstantiallyinotherdomains,we
standreadytoextendthisprovisiontothosedomainsinfutureversions
oftheGPL,asneededtoprotectthefreedomofusers.

Finally,everyprogramisthreatenedconstantlybysoftwarepatents.

avoidthespecialdangerthatpatentsappliedtoafreeprogramcould
