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 rst 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library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library.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library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.
Whena programislinkedwithalibrary, whetherstaticallyorusinga
sharedlibrary,thecombinationofthetwoislegallyspeakingacombined
work, a derivative of the original library.The ordinary General Public
Licensethereforepermitssuchlinkingonlyiftheentirecombinationts
