Although the Lesser General Public License is Less
protective of the users' freedom, it does ensure that the

freedomandthewherewithaltorunthatprogramusinga

Theprecisetermsandconditionsforcopying,distribution
and modification follow. Pay close attention to the
difference between a"work based on the library" and a
"work that uses the library". The former contains code
derived from the library, whereas the latter must be
combinedwiththelibraryinordertorun.

or any derivative work under copyright law: that is
to say, a work containing the Library or a portion
of it, either verbatim or with modifications and/or
translated straightforwardly into another language.
(Hereinafter,translationisincludedwithoutlimitation

AppendixE:SoftwareEndUserLicenseAgreement
1. You may copy and distribute verbatim copies of the
Library's complete 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
intactallthenoticesthatrefertothisLicenseandto

Youmaychargeafeeforthephysicalactoftransferring

2. YoumaymodifyyourcopyorcopiesoftheLibraryor
any portion of it, thus forming a work based on the
Library, and copy and distribute such modifications
orworkunderthetermsofSection1above,provided
thatyoualsomeetalloftheseconditions:

b. You must cause the files modified to carry
prominent notices stating that you changed the
filesandthedateofanychange.
c. You must cause the whole of the work to be
licensedatnochargetoallthirdpartiesunderthe
termsofthisLicense.
d. If a facility in the modified Library refers to a
function or a table of data to be supplied by an
application program that uses the facility, other
than as an argument passed when the facility is
invoked, then you must make a good faith effort
to ensure that, in the event an application does
not supply such function or table, the facility
still operates, and performs whatever part of its
purposeremainsmeaningful.
(Forexample,afunctioninalibrarytocomputesquare

2drequiresthatanyapplication-suppliedfunctionor
table used by this function must be optional: if the
applicationdoesnotsupplyit,thesquarerootfunction

These requirements apply to the modified work as
a whole.If identifiable sections ofthat work are not
derived from the Library, and can be reasonably
considered independent and separate works in
themselves, then this License, and its terms, do not
