The licenses for most software are designed to take awa y your freedom to
share and change it. By c ontrast, the GN U General Public License is
intended to guarantee your freedom to share and cha nge free software—to
make sure the software is free for all its use rs. This General Public License
applies to most of the Fr ee Soft ware F oun dation’s soft ware and to any other
program whose autho rs commit to using i t. (Some o ther Free Sof t ware
Foundation software is covered by the GNU Lesser G eneral Public License
instead.) Y ou ca n apply it to your programs, too .
When we speak o f free software, we are ref err ing to freedom, no t price. Our
General Public Licenses are desi gned to make sure that you have the
free dom to distrib ute copi es of fr ee softwar e (and char ge for this service if
you wish), that you receive source cod e or can get it if you want it, tha t you
can chang e the software or use pi eces of it in n ew free progr ams; and that
you know you can do these things.
T o protect your rights, we need to make restricti ons that forbid anyone to
deny you these ri ghts or to ask you to surrender the rights. Thes e restrictions
translate to cer tain responsi bilities for you if you distr ibute copies of the
software, or if you modify it.
For ex ample, if you distr ibute copies of such a program, whe ther gratis or for
a fee , you m ust giv e the reci pients all the rig hts that you hav e. Y ou must
make sure that they , too, receive or can get the source cod e. And you must
show them thes e terms so they know their righ ts.
We prot ect your r ights with t wo steps: (1) co pyright the softwa re, and (2) off er
you this licens e which gives you legal per missi on to copy , distri bute and/or
modify th e sof t war e.
Also, f or ea ch author's protection and ours, we want to make certai n that
ev er yone understands that the re is no warranty for this free software. If the
sof t war e is modifi ed by someo ne else and passed on, we wan t its recipi ents
to know that what they have is not the or iginal, so that any problems
introduced by others will not reflect on th e origina l authors’ reputations.
Fina lly , any free pr ogram is t hreat ened consta ntly b y sof t war e patents . W e
wish to avoid the danger that redistr ibutors of a free program will individual ly
obtain patent lice nses, in effect making the program proprietar y . T o prev ent
this, we have made it clear that any patent must be licensed for everyone’s
free use or not licens ed at all.
The precise ter ms and cond itions for copying, distribution and modification

TERMS AND CONDITIONS FOR
COP YING, DISTRIBU TION AND
MODIFIC A TION
0. This License applie s to any pr ogra m or other work whi ch contains a
notice plac ed by the copyright ho lder saying it may be distr ibuted under
the terms o f this Genera l Pub lic Lice nse. The “Program”, b el ow, refers to
any such program or wor k, and a “wor k based o n the Prog ram” means
either the Progr am or any d erivative work under co pyright law: that is to
say , a work con taining the Program or a port ion of it, eit her verbatim or
with modifications and/or translated into another language. (Hereinafter ,
translation is included w ithout limitation in the ter m “modificatio n”.) Each
licensee i s addressed as “you”.
Activities other than copying, distribution and modificatio n are not
covered b y this L icense; they are outside its scope. The act of ru nning
the Pr ogram is no t restricted, and t he output f rom the P rogram is covered
only if its contents consti tute a work base d on the Pr ogram (indep endent
of having been mad e by running the P rogram). Whether that is tr ue
depends on wh at the Pr ogram does.
1. Y ou may cop y and distrib ute v erbatim copies of the P rogr am’s sour ce
code as you receive it, in any m edium, provided that you conspicuous ly
and appropriately publish on ea ch copy an appropriate co pyright notice
and disclaime r of warrant y; keep intact all the notices th at refer to this
License and to the absence of any warranty; and give any other
recipients of the Program a copy of this License along with the Pr ogram.
Y ou may charge a fee for the phy sical act of tran sferring a copy , and you
may at your opti on of fer w arranty prot ection in ex change f or a fee .
2. Y ou may modi fy your copy or copies of the P rogram or any por tion of it,
thus formin g a work bas ed on the Program, and copy and distribute such
modifi cations or wo rk under the terms of Sec tion 1 abov e, pr ovided t hat
you al so meet all of thes e conditions:
a) Y ou must cause the mo dified files to carr y prominent n otices stating
that you changed the files and the date of any change.
b)Y ou must ca use any work that you distri bute or publish, that in whol e
or in par t contain s or is der ived from the P rogram or any par t thereof,
to be licensed as a whole at no charge to all third par ties under the
terms of t his Licens e.
c) If the modified program normally reads com mands interactively when
run, you must cause it, whe n star ted runni ng for such interactive use
in the most ordinary way , to print o r display an announc ement
including an appropriate copyright notice and a notice th at there is no
warra nty (or else, sa ying that y ou provi de a warran ty) and that users
may redistribute the program under these conditio ns, and telling the
user how to view a copy of this Licens e. (Exception: if the Program
itself is interactive but does not n orm ally print such a n announc ement,
your work based on t he Pr ogram is not r equir ed to print an
announce ment.)
These r equir ements appl y to t he modifi ed work as a whole. If identif iable
sections of that work are no t derived from the Pr ogram, a nd can be
reasonably considered independ ent and separa te works in thems elves ,
then this L icense, and its ter ms, do not app ly to those sections when you
distrib ute them as sep arate w orks. But when y ou distrib ute the s ame
sections as par t of a whole which is a work based o n the Pr ogram, the
distribution of the whole mus t be on the ter ms of this Li cense, whose
perm issions for other lice nsees extend to the entire whole, and thus to
each and e very part reg ardless of wh o wrot e it.
Thus, it is not t he intent of this section to claim r ights o r contest your
rights to wor k written entirely b y you; rather , the intent is to ex ercise the
right to control the di stribution of d erivative or collective works ba sed on
the P rogram.
In addition, mere aggregation of another wor k not based on the Pr ogram
with the Program (or with a work based on the Program) on a volume of
a storage or distribution me dium does not br ing the other wor k under the
scope of this License.
3. Y ou may c opy and dis tribut e the P rogr am (or a work based on it, under
Section 2) in object cod e or executable f orm under the ter ms of Se ctions
1 and 2 above provided that you also do one of the following:
a) Accom pany it with the complet e corres ponding machine - readab le
source c ode, which must be distrib uted un der the te r ms of Sectio ns 1
and 2 above on a medium customarily used for sof t ware interchange;
or ,
b)Accomp any it with a written of fer , valid for at least three year s, to give
any thir d party , for a char ge no more tha n your cost of phy sically
performing so urce distr ibution, a complete mac hine- readable copy of
the correspon ding source code, to be dis tributed under the terms of
Sections 1 an d 2 abov e on a medium cus tomarily us ed for sof t ware
interchange; or,
c) Accompany it with the informatio n you received as to the off er to
distri bute corresponding so urce code. (This al ternative is al lowed only
for noncommercial distr ibution and only if you received the program in
object code or ex ecutab le form with su ch an of fer , in accord with
Subsecti on b abov e.)
The source code for a work m eans the preferred form of the wor k for
making mod ifications to it. F or an executable work, comple te source
code means all the sou rce code for all modul es it contains, pl us any
associated interface definition files, plus the scr ipts used to control
compilation and installati on of the executable . Ho wever , as a special
ex ception, th e source code dist ributed need not inc lude anything that i s
normally di stributed (in either sour ce or binary f orm) with the major
components (compile r , kernel , and so on ) of the operati ng system on
which the ex ecutable ru ns, unless th at compon ent itself accompanie s
the ex ecutable.
If distrib ution of e xec utable o r object code is mad e by of fering access to
copy f rom a desig nated pla ce, then of f ering equiv alent access t o copy
the sour ce code from t he same place count s as distributi on of the sour ce
code, e ve n though thir d parties are not c ompelled t o copy th e source
along with the objec t code.
