Preamble
Thelicensesformostsoftwarearedesignedtotakeawayyourfreedom
toshareandchangeit.Bycontrast,theGNUGeneralPublicLicensesare
intendedtoguaranteeyourfreedomtoshareandchangefreesoftware
tomakesurethesoftwareisfreeforallitsusers.
Thislicense,theLesserGeneralPublicLicense,appliestosomespecially
designatedsoftware packages--typically libraries--of the Free Software
Foundationandotherauthorswho decidetouseit.Youcanuseittoo,
butwesuggest you r st think carefully about whether this license or
theordinaryGeneralPublic Licenseisthebetterstrategy touseinany
particularcase,basedontheexplanationsbelow.
Whenwespeakof freesoftware,weare referringto freedomofuse,
notprice.Our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receivesourcecodeorcangetitif
youwantit;thatyoucanchangethesoftwareandusepiecesofitinnew
freeprograms;andthatyouareinformedthatyoucandothesethings.
To protect your rights,we need to make restrictions that forbid
distributorstodeny youtheserightsor toaskyouto surrenderthese
rights.Theserestrictionstranslatetocertainresponsibilitiesforyouifyou
distributecopiesofthelibraryorifyoumodifyit.
Forexample,ifyoudistributecopiesofthelibrary,whethergratisorfora
fee,youmustgivetherecipientsalltherightsthatwegaveyou.Youmust
makesurethatthey,too,receiveorcangetthesourcecode.If youlink
othercodewiththe library,youmustprovidecomplete objectlesto
therecipients,sothattheycanrelinkthemwiththelibrar yaftermaking
changestothelibraryandrecompilingit.Andyoumustshowthemthese
termssotheyknowtheirrights.
Weprotectyourrights withatwo-stepmethod: (1)wecopyrightthe
library,and(2)weofferyouthislicense,whichgivesyoulegalpermission
tocopy,distributeand/ormodifythelibrary.
Toprotecteachdistributor,wewanttomakeitveryclearthatthereisno
warrantyforthefreelibrar y.Also,ifthelibraryismodiedbysomeone
elseandpassedon,therecipientsshouldknowthatwhattheyhaveisnot
theoriginalversion,so thattheoriginal author'sreputationwillnot be
affectedbyproblemsthatmightbeintroducedbyothers.
Finally,softwarepatentsposeaconstantthreat totheexistenceof any
freeprogram.Wewishtomakesurethatacompany cannoteffectively
restricttheusersofafreeprogrambyobtainingarestrictivelicensefrom
apatentholder.Therefore,weinsistthatanypatentlicenseobtained for
aversionofthelibrar ymustbeconsistentwiththefull freedomofuse
speciedinthislicense.
MostGNUsoftware,includingsomelibraries,iscoveredbytheordinary
GNUGeneral Public License.This license ,the GNU Lesser General
PublicLicense,appliestocertaindesignatedlibraries,andisquitedifferent
fromtheordinaryGeneralPublicLicense.Weusethislicenseforcertain
librariesinordertopermitlinkingthoselibrariesintonon-freeprograms.
