below,referstoanysuch programorwork,and a"workbased
onthe Program" means either the Program or any derivative

Programoraportionofit,eitherverbatimorwithmodications
and/ortranslatedintoanother language.(Hereinafter,translation
isincluded without limitation in the term“modication".) Each
licensee is addressed as“you”. Activities other than copying,
distributionand modication are not covered by this License;
theyareoutsideitsscope.TheactofrunningtheProgramisnot
restricted,andtheoutputfromtheProgramis coveredonlyifits
contentsconstituteaworkbasedon theProgram(independent
ofhavingbeenmade byrunningthe Program).Whetherthatis
truedependsonwhattheProgramdoes.
1.  Youmaycopyand distributeverbatimcopies oftheProgram's
sourcecode as you receive it, in any medium,provided that
youconspicuously and appropriately publish on each copy an
appropriatecopyright notice and disclaimer of warranty; keep
intactallthenoticesthatrefertothisLicenseandtotheabsence
ofanywarranty;andgive anyotherrecipientsofthe Programa

2. Youmay modify your copy or copies of the Program or any
portionof it,thusforming awork basedon theProgram,and
copyanddistributesuchmodicationsorworkunder theterms
ofSection 1 above, provided that youalso meet all of these
conditions:
 a)Youmustcausethemodiedlestocarr yprominentnotices
statingthatyouchangedthelesandthedateofanychange.
 b)Youmustcauseanyworkthatyoudistributeorpublish,thatin
wholeorinpar tcontainsoris derivedfromthe Programor
anypartthereof,tobelicensedasawholeat nochargetoall
thirdpartiesunderthetermsofthisLicense.
 c)Ifthemodiedprogramnormallyreadscommandsinteractively
whenrun,you mustcauseit,when started runningforsuch
interactiveuseinthemostordinaryway,toprintordisplayan
announcementincludinganappropriatecopyrightnoticeanda
noticethatthereisnowarranty(orelse,sayingthatyouprovide
awarranty)andthatusersmayredistributetheprogramunder
theseconditions,andtellingtheuserhowtoviewacopyofthis
License.(Exception:iftheProgramitselfisinteractivebutdoes
notnormallyprintsuchanannouncement,yourworkbasedon
theProgramisnotrequiredtoprintanannouncement.)
Theserequirementsapply to the modied work as a whole .
Ifidentiable sections of that work are not derived from the
Program,and can be reasonably considered independent and
separateworksinthemselves,thenthisLicense,anditsterms,do
notapplytothosesectionswhenyoudistributethemasseparate
works.Butwhen youdistributethe samesectionsas partof a
wholewhichisaworkbasedontheProgram,thedistributionof
thewholemustbeonthetermsofthisLicense,whosepermissions
forotherlicenseesextendtotheentirewhole,andthus toeach
andeverypartregardlessofwhowroteit.
 Thus,itisnottheintentofthissectionto claimrightsorcontest
yourrightsto workwrittenentirely byyou;rather,theintentis
toexercisetheright tocontrolthe distributionofderivative or

Inaddition,mere aggregation of another work not based on
