    changing itis not allowed.
     Preamble
    
    The
    licenses formost software aredesigned totake away yourfreedom toshare andchange it.By
     contrast,
    theGNU General PublicLicense isintended toguarantee yourfreedom toshare andchange
     free
    software--to makesurethesoftware isfree forallitsusers. ThisGeneral PublicLicense appliesto
     most
    ofthe Free Software Foundations softwareandtoany other program whoseauthors committo
     using
    it.(Some otherFreeSoftware Foundation softwareiscovered bythe GNU Lesser General Public
     License
    instead.) Youcanapply itto your programs, too.
     When
    wespeak offree software, weare referring tofreedom, notprice. OurGeneral PublicLicenses are
     designed
    tomake surethatyouhave thefreedom todistribute copiesoffree software (andcharge for
     223 
    						
    							
    
    this
    service ifyou wish), thatyoureceive sourcecodeorcan getitifyou want it,that youcanchange the
     software
    oruse pieces ofitin new freeprograms; andthatyouknow youcandothese things.
     To
    protect yourrights, weneed tomake restrictions thatforbid anyone todeny youthese rightsortoask
     you
    tosurrender therights. These restrictions translatetocertain responsibilities foryou ifyou distribute
     copies
    ofthe software, orifyou modify it.
     For
    example, ifyou distribute copiesofsuch aprogram, whethergratisorfor afee, youmust givethe
     recipients
    allthe rights thatyouhave. Youmust make surethatthey, too,receive orcan getthesource
     code.
    Andyoumust show themthese terms sothey know theirrights.
     We
    protect yourrights withtwosteps: (1)copyright thesoftware, and(2)offer youthislicense which
     gives
    youlegal permission tocopy, distribute and/ormodify thesoftware.
     Also,
    foreach authors protection andours, wewant tomake certain thateveryone understands that
     there
    isno warranty forthis free software. Ifthe software ismodified bysomeone elseandpassed on,
     we
    want itsrecipients toknow thatwhat theyhave isnot theoriginal, sothat anyproblems introduced by
     others
    willnot reflect onthe original authors reputations.
     Finally,
    anyfree program isthreatened constantlybysoftware patents.Wewish toavoid thedanger that
     redistributors
    ofafree program willindividually obtainpatent licenses, ineffect making theprogram
     proprietary.
    Toprevent this,wehave made itclear thatanypatent mustbelicensed foreveryones free
     use
    ornot licensed atall.
     The
    precise termsandconditions forcopying, distribution andmodification follow.
     GNU
    GENERAL PUBLICLICENSE TERMSANDCONDITIONS FORCOPYING, DISTRIBUTION AND
     MODIFICATION
    
    0.
    This License appliestoany program orother workwhich contains anotice placed bythe copyright
     holder
    saying itmay bedistributed undertheterms ofthis General PublicLicense. TheProgram,
     below,
    referstoany such program orwork, andawork based onthe Program meanseitherthe
     Program
    orany derivative workunder copyright law:thatisto say, awork containing theProgram ora
     portion
    ofit,either verbatim orwith modifications and/ortranslated intoanother language. (Hereinafter,
     translation
    isincluded withoutlimitation inthe term modification.) Eachlicensee isaddressed asyou.
     Activities
    otherthancopying, distribution andmodification arenotcovered bythis License; theyare
     outside
    itsscope. Theactofrunning theProgram isnot restricted, andtheoutput fromtheProgram is
     covered
    onlyifits contents constitute awork based onthe Program (independent ofhaving beenmade
     by
    running theProgram). Whetherthatistrue depends onwhat theProgram does.
     1.
    You may copy anddistribute verbatimcopiesofthe Programs sourcecodeasyou receive it,in any
     medium,
    provided thatyouconspicuously andappropriately publishoneach copyanappropriate
     copyright
    noticeanddisclaimer ofwarranty; keepintact allthe notices thatrefer tothis License andtothe
     absence
    ofany warranty; andgive anyother recipients ofthe Program acopy ofthis License alongwith
     the
    Program.
     224 
    						
    							
    
    You
    may charge afee forthe physical actoftransferring acopy, andyoumay atyour option offer
     warranty
    protection inexchange forafee.
     2.
    You may modify yourcopy orcopies ofthe Program orany portion ofit,thus forming awork based on
     the
    Program, andcopy anddistribute suchmodifications orwork under theterms ofSection 1above,
     provided
    thatyoualso meet allofthese conditions:
     a)
    You must cause themodified filestocarry prominent noticesstatingthatyouchanged thefiles andthe
     date
    ofany change.
     b)
    You must cause anywork thatyoudistribute orpublish, thatinwhole orinpart contains orisderived
     from
    theProgram orany part thereof, tobe licensed asawhole atno charge toall third parties underthe
     terms
    ofthis License.
     c)
    Ifthe modified programnormally readscommands interactively whenrun,youmust cause it,when
     started
    running forsuch interactive useinthe most ordinary way,toprint ordisplay anannouncement
     including
    anappropriate copyrightnoticeandanotice thatthere isno warranty (orelse, saying thatyou
     provide
    awarranty) andthatusers mayredistribute theprogram undertheseconditions, andtelling the
     user
    howtoview acopy ofthis License. (Exception: ifthe Program itselfisinteractive butdoes not
     normally
    printsuch anannouncement, yourwork based onthe Program isnot required toprint an
     announcement.)
    
    These
    requirements applytothe modified workasawhole. Ifidentifiable sectionsofthat work arenot
     derived
    fromtheProgram, andcanbereasonably consideredindependent andseparate worksin
     themselves,
    thenthisLicense, anditsterms, donot apply tothose sections whenyoudistribute themas
     separate
    works.Butwhen youdistribute thesame sections aspart ofawhole whichisawork based on
     the
    Program, thedistribution ofthe whole mustbeonthe terms ofthis License, whosepermissions for
     other
    licensees extendtothe entire whole, andthus toeach andevery partregardless ofwho wrote it.
     Thus,
    itis not theintent ofthis section toclaim rights orcontest yourrights towork written entirely by
     you;
    rather, theintent isto exercise theright tocontrol thedistribution ofderivative orcollective works
     based
    onthe Program.
     In
    addition, mereaggregation ofanother worknotbased onthe Program withtheProgram (orwith a
     work
    based onthe Program) onavolume ofastorage ordistribution mediumdoesnotbring theother
     work
    under thescope ofthis License.
     3.
    You may copy anddistribute theProgram (orawork based onit,under Section 2)inobject codeor
     executable
    formunder theterms ofSections 1and 2above provided thatyoualso doone ofthe
     following:
    
    a)
    Accompany itwith thecomplete corresponding machine-readable sourcecode,which mustbe
     distributed
    undertheterms ofSections 1and 2above onamedium customarily usedforsoftware
     interchange;
    or,
     225 
    						
    							
    
    b)
    Accompany itwith awritten offer,validforatleast three years, togive anythird party, foracharge no
     more
    thanyourcostofphysically performing sourcedistribution, acomplete machine-readable copyof
     the
    corresponding sourcecode,tobe distributed undertheterms ofSections 1and 2above ona
     medium
    customarily usedforsoftware interchange; or,
     c)
    Accompany itwith theinformation youreceived astothe offer todistribute corresponding source
     code.
    (Thisalternative isallowed onlyfornoncommercial distributionandonly ifyou received the
     program
    inobject codeorexecutable formwithsuch anoffer, inaccord withSubsection babove.)
     The
    source codeforawork means thepreferred formofthe work formaking modifications toit.For an
     executable
    work,complete sourcecodemeans allthe source codeforallmodules itcontains, plusany
     associated
    interfacedefinition files,plusthescripts usedtocontrol compilation andinstallation ofthe
     executable.
    However,asaspecial exception, thesource codedistributed neednotinclude anything that
     is
    normally distributed (ineither source orbinary form)withthemajor components (compiler,kernel,and
     so
    on) ofthe operating systemonwhich theexecutable runs,unless thatcomponent itselfaccompanies
     the
    executable.
     If
    distribution ofexecutable orobject codeismade byoffering accesstocopy fromadesignated place,
     then
    offering equivalent accesstocopy thesource codefromthesame placecounts asdistribution of
     the
    source code,eventhough thirdparties arenotcompelled tocopy thesource alongwiththeobject
     code.
    
    4.
    You may notcopy, modify, sublicense, ordistribute theProgram exceptasexpressly providedunder
     this
    License. Anyattempt otherwise tocopy, modify, sublicense ordistribute theProgram isvoid, andwill
     automatically
    terminateyourrights under thisLicense. However, partieswhohave received copies,or
     rights,
    fromyouunder thisLicense willnot have theirlicenses terminated solong assuch parties remain
     in
    full compliance.
     5.
    You arenotrequired toaccept thisLicense, sinceyouhave notsigned it.However, nothingelse
     grants
    youpermission tomodify ordistribute theProgram orits derivative works.Theseactions are
     prohibited
    bylaw ifyou donot accept thisLicense. Therefore, bymodifying ordistributing theProgram
     (or
    any work based onthe Program), youindicate youracceptance ofthis License todo so, and allits
     terms
    andconditions forcopying, distributing ormodifying theProgram orworks based onit.
     6.
    Each timeyouredistribute theProgram (orany work based onthe Program), therecipient
     automatically
    receivesalicense fromtheoriginal licensor tocopy, distribute ormodify theProgram
     subject
    tothese terms andconditions. Youmay notimpose anyfurther restrictions onthe recipients
     exercise
    ofthe rights granted herein.Youarenotresponsible forenforcing compliance bythird parties to
     this
    License.
     7.
    If,as aconsequence ofacourt judgment orallegation ofpatent infringement orfor any other reason
     (not
    limited topatent issues), conditions areimposed onyou (whether bycourt order, agreement or
     otherwise)
    thatcontradict theconditions ofthis License, theydonot excuse youfrom theconditions of
     this
    License. Ifyou cannot distribute soastosatisfy simultaneously yourobligations underthisLicense
     and
    anyother pertinent obligations, thenasaconsequence youmay notdistribute theProgram atall.
     226 
    						
    							
    
    For
    example, ifa patent license wouldnotpermit royalty-free redistribution ofthe Program byallthose
     who
    receive copiesdirectly orindirectly throughyou,then theonly wayyoucould satisfy bothitand this
     License
    wouldbetorefrain entirely fromdistribution ofthe Program.
     If
    any portion ofthis section isheld invalid orunenforceable underanyparticular circumstance, the
     balance
    ofthe section isintended toapply andthesection asawhole isintended toapply inother
     circumstances.
    
    It
    is not thepurpose ofthis section toinduce youtoinfringe anypatents orother property rightclaims or
     to
    contest validityofany such claims; thissection hasthesole purpose ofprotecting theintegrity ofthe
     free
    software distribution system,whichisimplemented bypublic license practices. Manypeople have
     made
    generous contributions tothe wide range ofsoftware distributed throughthatsystem inreliance on
     consistent
    application ofthat system; itis up tothe author/donor todecide ifhe orshe iswilling to
     distribute
    softwarethroughanyother system andalicensee cannotimpose thatchoice.
     This
    section isintended tomake thoroughly clearwhatisbelieved tobe aconsequence ofthe rest ofthis
     License.
    
    8.
    Ifthe distribution and/oruseofthe Program isrestricted incertain countries eitherbypatents orby
     copyrighted
    interfaces,theoriginal copyright holderwhoplaces theProgram underthisLicense mayadd
     an
    explicit geographical distributionlimitationexcluding thosecountries, sothat distribution ispermitted
     only
    inor among countries notthus excluded. Insuch case, thisLicense incorporates thelimitation asif
     written
    inthe body ofthis License.
     9.
    The Free Software Foundation maypublish revised and/ornewversions ofthe General Public
     License
    fromtimetotime. Such newversions willbesimilar inspirit tothe present version, butmay differ
     in
    detail toaddress newproblems orconcerns.
     Each
    version isgiven adistinguishing versionnumber. Ifthe Program specifies aversion number ofthis
     License
    whichapplies toitand any laterversion, youhave theoption offollowing theterms and
     conditions
    eitherofthat version orofany later version published bythe Free Software Foundation. Ifthe
     Program
    doesnotspecify aversion number ofthis License, youmay choose anyversion everpublished
     by
    the Free Software Foundation.
     10.
    Ifyou wish toincorporate partsofthe Program intoother freeprograms whosedistribution conditions
     are
    different, writetothe author toask forpermission. Forsoftware whichiscopyrighted bythe Free
     Software
    Foundation, writetothe Free Software Foundation; wesometimes makeexceptions forthis.
     Our
    decision willbeguided bythe two goals ofpreserving thefree status ofall derivatives ofour free
     software
    andofpromoting thesharing andreuse ofsoftware generally.
