acceptance of this License to do so, and all
itsterms and conditions lbr copying,

works based on it.
6. Each time you redistribute the Program lot
any work based on the Program), the
recipient automaticaUy receives a license
from the original licensor to copy, distribute
or modil3,the Program subject to these
terms and conditions. You may not impose
any further restrictions on tile recipients'
exercise of the rights granted herein. You
are not responsible lbr enforcing
compliance by third parties to this License.
7. IL as aconsequence of a court.judgment or
allegation of patent infringementor for any
other reason (not limited to patent issues),
conditions are imposed on you {whether by
court order, agreement or otherwise) that
contradict Ihe conditions of this License,
they do not excuse you from the conditions
ofthis License. lfyou cannot distribute soas
to satisfy simultaneously your obligations
under this License and any other pertinent
obligations, then as a consequence you may
not distribute the Program at all. For
example, if a patent license would not
permit royaltyq'reeredistribution of the
Program by all those who receive copies
directly or indirectly through you, then the
only way you could satisl_ both it and this
License would be to refrain entirely from
distribution of the Program.
Ifany portion of this section isheld invalid
or unenlbrceable under any pal_icular
circumstance, tile balance of Ihe section is
intendedtoapply and the section is a whole
is intended to apply inother circumstances.
It isnot the purpose of Ihis section to induce
you to infringe any patents orother properly
right claims or to contest validity of any
such claims: this section has the sole
puq)ose of protecting the integrity of the
free software distribution system, which is
implementedby public license practices.
Many people have made generous
contributions to the wide range of sol}wire
distributed tim)ugh that system in reliance
onconsistent application of that system; it is
up to the authoddonor to decide ifhe or she
iswilling to distribute software through any
other system and a licensee cannot impose
that choice.
This section isintended to make thoroughly
clelr what isbelieved to be a consequence
of the rest of this License.
8. Ifthe distribution and/or use of the Program
isrestricted in certain countries either by
patents or by copyrighted interfaces, the
original copyright holder who places the
Program under this License may add an
explicit geographical distribution limitation
excluding those countries, so that
distribution is permitted only in or among
countries not thus excluded. In such case,
this License incorporates thelimitation as if
written in the body of this License.
9. The Free Software Foundation may publish
revised and/or new versions of the General
Public License from time to time. Such new
versions will be similar in spirit to the
present version, but may differ indetail to
address new problems or concerns.
Each version is given a distinguishing
version number. If the Program specifies a
version number of this License which
applies to it and "any later version", you
have Ihe option of following the terms and
conditions either of that version or of any
later version published by the Free Soflw im
Foundation. If the Program does not specify
a version number of this License, you may
choose any version ever published by the
Free Software Foundation.
10. Ifyou wish to incorporate paris of the
Program into other ftce programs whose
distribution conditions aredifferent, write to
the author to ask for permission. For
software which iscopyrighted by the Free
Software Foundation, write to the Free
Software Foundation: we sometimes make
exceplions for this. Our decision will be
guided by the two goals of preserving the
free status of all derivatives of our free
software and of promoting the sharing and
reuse of soflware generally.

New Programs
Ifyou devcl%_a newprogram, and you want it to
be of Ihe greatest possible use to the public, the
best way to achieve this is tomake itfree
software which everyone can redistribute and
change under these terms.
To do so, attach the following notices to tile
program. It is safest to attach them tothe start of
each source file to most effectively convey the
exclusion of warranty: and each file should have
at least tile "copyright" line and a pointer to
where the full notice is Rmnd.
<one line to give the program's name and an

This General Pnblic License does not permit
incorporating your progr m_into proprietary

permit linking proprietary applications with Ihe
library. Ifthis is what you want to do, use the

Everyone ispermitted to copy and distribute

changing it is not allowed.

4,Preamble
The licenses for most sol}ware 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 youfirst think carefully about
whether this license or the ordinary General
Public License isthe 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 ,re designed to make surethat you have
the fieedom to distribute copies of free software
(rod 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
inlom/ed that you can do these things.
To protect your rights, we need tomake
restrictions that fi)rbid 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 grltis orfor a IL.e,you must give
therecipients 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 files to
the recipients, so that they can relink them with
the library after making changes tothe library
