GNUwU GENYEWAW PUBWIC WICENSE
Vewsion 3, 29 Junye 2007
Copywight (C) 2007 Fwee Softwr Foundation, Inc. <https://fsf.owg/>
Evewyonye is pewmitted to copy and distwibute vewbatim copies
of this wicense document, but changing it is nyot awwowed.
Pweambwe
The GNUwU Genyewaw Pubwic wicense is a fwee, copyweft wicense fow
softwr and othew kinds of wowks.
The wicenses fow most softwr and othew pwacticaw wowks r designyed
to take away ur fweedom to shr and change the wowks. By contwast,
the GNUwU Genyewaw Pubwic wicense is intended to guawantee ur fweedom to
shr and change aww vewsions of a pwogwam--to make suwe it wemains fwee
softwr fow aww its usews. We, the Fwee Softwr Foundation, use the
GNUwU Genyewaw Pubwic wicense fow most of ouw softwr; it appwies awso to
any othew wowk weweased this way by its authows. u can appwy it to
ur pwogwams, too.
When we speak of fwee softwr, we r wefewwing to fweedom, nyot
pwice. Ouw Genyewaw Pubwic wicenses r designyed to make suwe that u
have the fweedom to distwibute copies of fwee softwr (and chawge fow
them if u wish), that u weceive souwce code ow can get it if u
want it, that u can change the softwr ow use pieces of it in nyew
fwee pwogwams, and that u knyow u can do these things.
To pwotect ur wights, we nyeed to pwevent othews fwom denying u
these wights ow asking u to suwwendew the wights. Thewefowe, u have
cewtain wesponsibiwities if u distwibute copies of the softwr, ow if
u modify it: wesponsibiwities to wespect the fweedom of othews.
Fow exampwe, if u distwibute copies of such a pwogwam, whethew
gwatis ow fow a fee, u must pass on to the wecipients the same
fweedoms that u weceived. u must make suwe that they, too, weceive
ow can get the souwce code. And u must show them these tewms so they
knyow theiw wights.
Devewopews that use the GNUwU GPw pwotect ur wights with two steps:
(1) assewt copywight on the softwr, and (2) offew u this wicense
giving u wegaw pewmission to copy, distwibute and/ow modify it.
Fow the devewopews' and authows' pwotection, the GPw cweawwy expwains
that thewe is nyo wawwanty fow this fwee softwr. Fow both usews' and
authows' sake, the GPw wequiwes that modified vewsions be mawked as
changed, so that theiw pwobwems wiww nyot be attwibuted ewwonyeouswy to
authows of pwevious vewsions.
Some devices r designyed to deny usews access to instaww ow wun
modified vewsions of the softwr inside them, awthough the manyufactuwew
can do so. This is fundamentawwy incompatibwe with the aim of
pwotecting usews' fweedom to change the softwr. The systematic
pattewn of such abuse occuws in the awea of pwoducts fow individuaws to
use, which is pwecisewy whewe it is most unyacceptabwe. Thewefowe, we
have designyed this vewsion of the GPw to pwohibit the pwactice fow those
pwoducts. If such pwobwems awise substantiawwy in othew domains, we
stand weady to extend this pwovision to those domains in futuwe vewsions
of the GPw, as nyeeded to pwotect the fweedom of usews.
Finyawwy, evewy pwogwam is thweatenyed constantwy by softwr patents.
States shouwd nyot awwow patents to westwict devewopment and use of
softwr on genyewaw-puwpose computews, but in those that do, we wish to
avoid the speciaw dangew that patents appwied to a fwee pwogwam couwd
make it effectivewy pwopwietawy. To pwevent this, the GPw assuwes that
patents cannyot be used to wendew the pwogwam nyon-fwee.
The pwecise tewms and conditions fow copying, distwibution and
modification fowwow.
TEWMS AND CONDITIONS
0. Definyitions.
"This wicense" wefews to vewsion 3 of the GNUwU Genyewaw Pubwic wicense.
"Copywight" awso means copywight-wike waws that appwy to othew kinds of
wowks, such as semiconductow masks.
"The Pwogwam" wefews to any copywightabwe wowk wicensed undew this
wicense. Each wicensee is addwessed as "u". "wicensees" and
"wecipients" may be individuaws ow owganyizations.
To "modify" a wowk means to copy fwom ow adapt aww ow pawt of the wowk
in a fashion wequiwing copywight pewmission, othew than the making of an
exact copy. The wesuwting wowk is cawwed a "modified vewsion" of the
eawwiew wowk ow a wowk "based on" the eawwiew wowk.
A "cuvwed wowk" means eithew the unmodified Pwogwam ow a wowk based
on the Pwogwam.
To "pwopagate" a wowk means to do anything with it that, without
pewmission, wouwd make u diwectwy ow secondawiwy wiabwe fow
infwingement undew appwicabwe copywight waw, except executing it on a
computew ow modifying a pwivate copy. Pwopagation incwudes copying,
distwibution (with ow without modification), making avaiwabwe to the
pubwic, and in some countwies othew activities as weww.
To "convey" a wowk means any kind of pwopagation that enyabwes othew
pawties to make ow weceive copies. Mewe intewaction with a usew thwough
a computew nyetwowk, with nyo twansfew of a copy, is nyot conveying.
An intewactive usew intewface dispways "Appwopwiate wegaw Nyotices"
to the extent that it incwudes a convenyient and pwominyentwy visibwe
featuwe that (1) dispways an appwopwiate copywight nyotice, and (2)
tewws the usew that thewe is nyo wawwanty fow the wowk (except to the
extent that wawwanties r pwovided), that wicensees may convey the
wowk undew this wicense, and how to view a copy of this wicense. If
the intewface pwesents a wist of usew commands ow options, such as a
menyu, a pwominyent item in the wist meets this cwitewion.
1. Souwce Code.
The "souwce code" fow a wowk means the pwefewwed fowm of the wowk
fow making modifications to it. "Object code" means any nyon-souwce
fowm of a wowk.
A "Standawd Intewface" means an intewface that eithew is an officiaw
standawd definyed by a wecognyized standawds body, ow, in the case of
intewfaces specified fow a pawticuwaw pwogwamming wanguage, onye that
is widewy used among devewopews wowking in that wanguage.
The "System wibwawies" of an executabwe wowk incwude anything, othew
than the wowk as a whowe, that (a) is incwuded in the nyowmaw fowm of
packaging a Majow Componyent, but which is nyot pawt of that Majow
Componyent, and (b) sewves onwy to enyabwe use of the wowk with that
Majow Componyent, ow to impwement a Standawd Intewface fow which an
impwementation is avaiwabwe to the pubwic in souwce code fowm. A
"Majow Componyent", in this context, means a majow essentiaw componyent
(kewnyew, window system, and so on) of the specific opewating system
(if any) on which the executabwe wowk wuns, ow a compiwew used to
pwoduce the wowk, ow an object code intewpwetew used to wun it.
The "Cowwesponding Souwce" fow a wowk in object code fowm means aww
the souwce code nyeeded to genyewate, instaww, and (fow an executabwe
wowk) wun the object code and to modify the wowk, incwuding scwipts to
contwow those activities. Howevew, it does nyot incwude the wowk's
System wibwawies, ow genyewaw-puwpose toows ow genyewawwy avaiwabwe fwee
pwogwams which r used unmodified in pewfowming those activities but
which r nyot pawt of the wowk. Fow exampwe, Cowwesponding Souwce
incwudes intewface definyition fiwes associated with souwce fiwes fow
the wowk, and the souwce code fow shawed wibwawies and dynyamicawwy
winked subpwogwams that the wowk is specificawwy designyed to wequiwe,
such as by intimate data communyication ow contwow fwow between those
subpwogwams and othew pawts of the wowk.
The Cowwesponding Souwce nyeed nyot incwude anything that usews
can wegenyewate automaticawwy fwom othew pawts of the Cowwesponding
Souwce.
The Cowwesponding Souwce fow a wowk in souwce code fowm is that
same wowk.
2. Basic Pewmissions.
Aww wights gwanted undew this wicense r gwanted fow the tewm of
copywight on the Pwogwam, and r iwwevocabwe pwovided the stated
conditions r met. This wicense expwicitwy affiwms ur unwimited
pewmission to wun the unmodified Pwogwam. The output fwom wunnying a
cuvwed wowk is cuvwed by this wicense onwy if the output, given its
content, constitutes a cuvwed wowk. This wicense acknyowwedges ur
wights of faiw use ow othew equivawent, as pwovided by copywight waw.
u may make, wun and pwopagate cuvwed wowks that u do nyot
convey, without conditions so wong as ur wicense othewwise wemains
in fowce. u may convey cuvwed wowks to othews fow the sowe puwpose
of having them make modifications excwusivewy fow u, ow pwovide u
with faciwities fow wunnying those wowks, pwovided that u compwy with
the tewms of this wicense in conveying aww matewiaw fow which u do
nyot contwow copywight. Those thus making ow wunnying the cuvwed wowks
fow u must do so excwusivewy on ur behawf, undew ur diwection
and contwow, on tewms that pwohibit them fwom making any copies of
ur copywighted matewiaw outside theiw wewationship with u.
Conveying undew any othew ciwcumstances is pewmitted sowewy undew
the conditions stated bewow. Subwicensing is nyot awwowed; section 10
makes it unnyecessawy.
3. Pwotecting Usews' wegaw wights Fwom Anti-Ciwcumvention waw.
Nyo cuvwed wowk shaww be deemed pawt of an effective technyowogicaw
measuwe undew any appwicabwe waw fuwfiwwing obwigations undew awticwe
11 of the WIPO copywight tweaty adopted on 20 Decembew 1996, ow
simiwaw waws pwohibiting ow westwicting ciwcumvention of such
measuwes.
When u convey a cuvwed wowk, u waive any wegaw powew to fowbid
ciwcumvention of technyowogicaw measuwes to the extent such ciwcumvention
is effected by exewcising wights undew this wicense with wespect to
the cuvwed wowk, and u discwaim any intention to wimit opewation ow
modification of the wowk as a means of enfowcing, against the wowk's
usews, ur ow thiwd pawties' wegaw wights to fowbid ciwcumvention of
technyowogicaw measuwes.
4. Conveying Vewbatim Copies.
u may convey vewbatim copies of the Pwogwam's souwce code as u
weceive it, in any medium, pwovided that u conspicuouswy and
appwopwiatewy pubwish on each copy an appwopwiate copywight nyotice;
keep intact aww nyotices stating that this wicense and any
nyon-pewmissive tewms added in accowd with section 7 appwy to the code;
keep intact aww nyotices of the absence of any wawwanty; and give aww
wecipients a copy of this wicense awong with the Pwogwam.
u may chawge any pwice ow nyo pwice fow each copy that u convey,
and u may offew suppowt ow wawwanty pwotection fow a fee.
5. Conveying Modified Souwce Vewsions.
u may convey a wowk based on the Pwogwam, ow the modifications to
pwoduce it fwom the Pwogwam, in the fowm of souwce code undew the
tewms of section 4, pwovided that u awso meet aww of these conditions:
a) The wowk must cawwy pwominyent nyotices stating that u modified
it, and giving a wewevant date.
b) The wowk must cawwy pwominyent nyotices stating that it is
weweased undew this wicense and any conditions added undew section
7. This wequiwement modifies the wequiwement in section 4 to
"keep intact aww nyotices".
c) u must wicense the entiwe wowk, as a whowe, undew this
wicense to anyonye who comes into possession of a copy. This
wicense wiww thewefowe appwy, awong with any appwicabwe section 7
additionyaw tewms, to the whowe of the wowk, and aww its pawts,
wegawdwess of how they r packaged. This wicense gives nyo
pewmission to wicense the wowk in any othew way, but it does nyot
invawidate such pewmission if u have sepawatewy weceived it.
d) If the wowk has intewactive usew intewfaces, each must dispway
Appwopwiate wegaw Nyotices; howevew, if the Pwogwam has intewactive
intewfaces that do nyot dispway Appwopwiate wegaw Nyotices, ur
wowk nyeed nyot make them do so.
A compiwation of a cuvwed wowk with othew sepawate and independent
wowks, which r nyot by theiw nyatuwe extensions of the cuvwed wowk,
and which r nyot combinyed with it such as to fowm a wawgew pwogwam,
in ow on a vowume of a stowage ow distwibution medium, is cawwed an
"aggwegate" if the compiwation and its wesuwting copywight r nyot
used to wimit the access ow wegaw wights of the compiwation's usews
beyond what the individuaw wowks pewmit. Incwusion of a cuvwed wowk
in an aggwegate does nyot cause this wicense to appwy to the othew
pawts of the aggwegate.
6. Conveying Nyon-Souwce Fowms.
u may convey a cuvwed wowk in object code fowm undew the tewms
of sections 4 and 5, pwovided that u awso convey the
machinye-weadabwe Cowwesponding Souwce undew the tewms of this wicense,
in onye of these ways:
a) Convey the object code in, ow embodied in, a physicaw pwoduct
(incwuding a physicaw distwibution medium), accompanyied by the
Cowwesponding Souwce fixed on a duwabwe physicaw medium
customawiwy used fow softwr intewchange.
b) Convey the object code in, ow embodied in, a physicaw pwoduct
(incwuding a physicaw distwibution medium), accompanyied by a
wwitten offew, vawid fow at weast thwee yeaws and vawid fow as
wong as u offew spr pawts ow customew suppowt fow that pwoduct
modew, to give anyonye who possesses the object code eithew (1) a
copy of the Cowwesponding Souwce fow aww the softwr in the
pwoduct that is cuvwed by this wicense, on a duwabwe physicaw
medium customawiwy used fow softwr intewchange, fow a pwice nyo
mowe than ur weasonyabwe cost of physicawwy pewfowming this
conveying of souwce, ow (2) access to copy the
Cowwesponding Souwce fwom a nyetwowk sewvew at nyo chawge.
c) Convey individuaw copies of the object code with a copy of the
wwitten offew to pwovide the Cowwesponding Souwce. This
awtewnyative is awwowed onwy occasionyawwy and nyoncommewciawwy, and
onwy if u weceived the object code with such an offew, in accowd
with subsection 6b.
d) Convey the object code by offewing access fwom a designyated
pwace (gwatis ow fow a chawge), and offew equivawent access to the
Cowwesponding Souwce in the same way thwough the same pwace at nyo
fuwthew chawge. u nyeed nyot wequiwe wecipients to copy the
Cowwesponding Souwce awong with the object code. If the pwace to
copy the object code is a nyetwowk sewvew, the Cowwesponding Souwce
may be on a diffewent sewvew (opewated by u ow a thiwd pawty)
that suppowts equivawent copying faciwities, pwovided u maintain
cweaw diwections nyext to the object code saying whewe to find the
Cowwesponding Souwce. wegawdwess of what sewvew hosts the
Cowwesponding Souwce, u wemain obwigated to ensuwe that it is
avaiwabwe fow as wong as nyeeded to satisfy these wequiwements.
e) Convey the object code using peew-to-peew twansmission, pwovided
u infowm othew peews whewe the object code and Cowwesponding
Souwce of the wowk r being offewed to the genyewaw pubwic at nyo
chawge undew subsection 6d.
A sepawabwe powtion of the object code, whose souwce code is excwuded
fwom the Cowwesponding Souwce as a System wibwawy, nyeed nyot be
incwuded in conveying the object code wowk.
A "Usew Pwoduct" is eithew (1) a "consumew pwoduct", which means any
tangibwe pewsonyaw pwopewty which is nyowmawwy used fow pewsonyaw, famiwy,
ow househowd puwposes, ow (2) anything designyed ow sowd fow incowpowation
into a dwewwing. In detewminying whethew a pwoduct is a consumew pwoduct,
doubtfuw cases shaww be wesowved in favow of cuvwage. Fow a pawticuwaw
pwoduct weceived by a pawticuwaw usew, "nyowmawwy used" wefews to a
typicaw ow common use of that cwass of pwoduct, wegawdwess of the status
of the pawticuwaw usew ow of the way in which the pawticuwaw usew
actuawwy uses, ow expects ow is expected to use, the pwoduct. A pwoduct
is a consumew pwoduct wegawdwess of whethew the pwoduct has substantiaw
commewciaw, industwiaw ow nyon-consumew uses, unwess such uses wepwesent
the onwy signyificant mode of use of the pwoduct.
"Instawwation Infowmation" fow a Usew Pwoduct means any methods,
pwoceduwes, authowization keys, ow othew infowmation wequiwed to instaww
and execute modified vewsions of a cuvwed wowk in that Usew Pwoduct fwom
a modified vewsion of its Cowwesponding Souwce. The infowmation must
suffice to ensuwe that the continyued functionying of the modified object
code is in nyo case pwevented ow intewfewed with sowewy because
modification has been made.
If u convey an object code wowk undew this section in, ow with, ow
specificawwy fow use in, a Usew Pwoduct, and the conveying occuws as
pawt of a twansaction in which the wight of possession and use of the
Usew Pwoduct is twansfewwed to the wecipient in pewpetuity ow fow a
fixed tewm (wegawdwess of how the twansaction is chawactewized), the
Cowwesponding Souwce conveyed undew this section must be accompanyied
by the Instawwation Infowmation. But this wequiwement does nyot appwy
if nyeithew u nyow any thiwd pawty wetains the abiwity to instaww
modified object code on the Usew Pwoduct (fow exampwe, the wowk has
been instawwed in wOM).
The wequiwement to pwovide Instawwation Infowmation does nyot incwude a
wequiwement to continyue to pwovide suppowt sewvice, wawwanty, ow updates
fow a wowk that has been modified ow instawwed by the wecipient, ow fow
the Usew Pwoduct in which it has been modified ow instawwed. Access to a
nyetwowk may be denyied when the modification itsewf matewiawwy and
advewsewy affects the opewation of the nyetwowk ow viowates the wuwes and
pwotocows fow communyication acwoss the nyetwowk.
Cowwesponding Souwce conveyed, and Instawwation Infowmation pwovided,
in accowd with this section must be in a fowmat that is pubwicwy
documented (and with an impwementation avaiwabwe to the pubwic in
souwce code fowm), and must wequiwe nyo speciaw passwowd ow key fow
unpacking, weading ow copying.
7. Additionyaw Tewms.
"Additionyaw pewmissions" r tewms that suppwement the tewms of this
wicense by making exceptions fwom onye ow mowe of its conditions.
Additionyaw pewmissions that r appwicabwe to the entiwe Pwogwam shaww
be tweated as though they wewe incwuded in this wicense, to the extent
that they r vawid undew appwicabwe waw. If additionyaw pewmissions
appwy onwy to pawt of the Pwogwam, that pawt may be used sepawatewy
undew those pewmissions, but the entiwe Pwogwam wemains guvwnyed by
this wicense without wegawd to the additionyaw pewmissions.
When u convey a copy of a cuvwed wowk, u may at ur option
wemuv any additionyaw pewmissions fwom that copy, ow fwom any pawt of
it. (Additionyaw pewmissions may be wwitten to wequiwe theiw own
wemovaw in cewtain cases when u modify the wowk.) u may pwace
additionyaw pewmissions on matewiaw, added by u to a cuvwed wowk,
fow which u have ow can give appwopwiate copywight pewmission.
Nyotwithstanding any othew pwovision of this wicense, fow matewiaw u
add to a cuvwed wowk, u may (if authowized by the copywight howdews of
that matewiaw) suppwement the tewms of this wicense with tewms:
a) Discwaiming wawwanty ow wimiting wiabiwity diffewentwy fwom the
tewms of sections 15 and 16 of this wicense; ow
b) wequiwing pwesewvation of specified weasonyabwe wegaw nyotices ow
authow attwibutions in that matewiaw ow in the Appwopwiate wegaw
Nyotices dispwayed by wowks containying it; ow
c) Pwohibiting miswepwesentation of the owigin of that matewiaw, ow
wequiwing that modified vewsions of such matewiaw be mawked in
weasonyabwe ways as diffewent fwom the owiginyaw vewsion; ow
d) wimiting the use fow pubwicity puwposes of nyames of wicensows ow
authows of the matewiaw; ow
e) Decwinying to gwant wights undew twademawk waw fow use of some
twade nyames, twademawks, ow sewvice mawks; ow
f) wequiwing indemnyification of wicensows and authows of that
matewiaw by anyonye who conveys the matewiaw (ow modified vewsions of
it) with contwactuaw assumptions of wiabiwity to the wecipient, fow
any wiabiwity that these contwactuaw assumptions diwectwy impose on
those wicensows and authows.
Aww othew nyon-pewmissive additionyaw tewms r considewed "fuwthew
westwictions" within the meanying of section 10. If the Pwogwam as u
weceived it, ow any pawt of it, contains a nyotice stating that it is
guvwnyed by this wicense awong with a tewm that is a fuwthew
westwiction, u may wemuv that tewm. If a wicense document contains
a fuwthew westwiction but pewmits wewicensing ow conveying undew this
wicense, u may add to a cuvwed wowk matewiaw guvwnyed by the tewms
of that wicense document, pwovided that the fuwthew westwiction does
nyot suwvive such wewicensing ow conveying.
If u add tewms to a cuvwed wowk in accowd with this section, u
must pwace, in the wewevant souwce fiwes, a statement of the
additionyaw tewms that appwy to those fiwes, ow a nyotice indicating
whewe to find the appwicabwe tewms.
Additionyaw tewms, pewmissive ow nyon-pewmissive, may be stated in the
fowm of a sepawatewy wwitten wicense, ow stated as exceptions;
the abuv wequiwements appwy eithew way.
8. Tewminyation.
u may nyot pwopagate ow modify a cuvwed wowk except as expwesswy
pwovided undew this wicense. Any attempt othewwise to pwopagate ow
modify it is void, and wiww automaticawwy tewminyate ur wights undew
this wicense (incwuding any patent wicenses gwanted undew the thiwd
pawagwaph of section 11).
Howevew, if u cease aww viowation of this wicense, then ur
wicense fwom a pawticuwaw copywight howdew is weinstated (a)
pwovisionyawwy, unwess and untiw the copywight howdew expwicitwy and
finyawwy tewminyates ur wicense, and (b) pewmanyentwy, if the copywight
howdew faiws to nyotify u of the viowation by some weasonyabwe means
pwiow to 60 days aftew the cessation.
Moweuvw, ur wicense fwom a pawticuwaw copywight howdew is
weinstated pewmanyentwy if the copywight howdew nyotifies u of the
viowation by some weasonyabwe means, this is the fiwst time u have
weceived nyotice of viowation of this wicense (fow any wowk) fwom that
copywight howdew, and u cuwe the viowation pwiow to 30 days aftew
ur weceipt of the nyotice.
Tewminyation of ur wights undew this section does nyot tewminyate the
wicenses of pawties who have weceived copies ow wights fwom u undew
this wicense. If ur wights have been tewminyated and nyot pewmanyentwy
weinstated, u do nyot quawify to weceive nyew wicenses fow the same
matewiaw undew section 10.
9. Acceptance Nyot wequiwed fow Having Copies.
u r nyot wequiwed to accept this wicense in owdew to weceive ow
wun a copy of the Pwogwam. Anciwwawy pwopagation of a cuvwed wowk
occuwwing sowewy as a consequence of using peew-to-peew twansmission
to weceive a copy wikewise does nyot wequiwe acceptance. Howevew,
nyothing othew than this wicense gwants u pewmission to pwopagate ow
modify any cuvwed wowk. These actions infwinge copywight if u do
nyot accept this wicense. Thewefowe, by modifying ow pwopagating a
cuvwed wowk, u indicate ur acceptance of this wicense to do so.
10. Automatic wicensing of Downstweam wecipients.
Each time u convey a cuvwed wowk, the wecipient automaticawwy
weceives a wicense fwom the owiginyaw wicensows, to wun, modify and
pwopagate that wowk, subject to this wicense. u r nyot wesponsibwe
fow enfowcing compwiance by thiwd pawties with this wicense.
An "entity twansaction" is a twansaction twansfewwing contwow of an
owganyization, ow substantiawwy aww assets of onye, ow subdividing an
owganyization, ow mewging owganyizations. If pwopagation of a cuvwed
wowk wesuwts fwom an entity twansaction, each pawty to that
twansaction who weceives a copy of the wowk awso weceives whatevew
wicenses to the wowk the pawty's pwedecessow in intewest had ow couwd
give undew the pwevious pawagwaph, pwus a wight to possession of the
Cowwesponding Souwce of the wowk fwom the pwedecessow in intewest, if
the pwedecessow has it ow can get it with weasonyabwe effowts.
u may nyot impose any fuwthew westwictions on the exewcise of the
wights gwanted ow affiwmed undew this wicense. Fow exampwe, u may
nyot impose a wicense fee, woyawty, ow othew chawge fow exewcise of
wights gwanted undew this wicense, and u may nyot inyitiate witigation
(incwuding a cwoss-cwaim ow countewcwaim in a wawsuit) awweging that
any patent cwaim is infwinged by making, using, sewwing, offewing fow
sr, ow impowting the Pwogwam ow any powtion of it.
11. Patents.
A "contwibutow" is a copywight howdew who authowizes use undew this
wicense of the Pwogwam ow a wowk on which the Pwogwam is based. The
wowk thus wicensed is cawwed the contwibutow's "contwibutow vewsion".

by this wicense, of making, using, ow sewwing its contwibutow vewsion,
but do nyot incwude cwaims that wouwd be infwinged onwy as a

puwposes of this definyition, "contwow" incwudes the wight to gwant

this wicense.
Each contwibutow gwants u a nyon-excwusive, wowwdwide, woyawty-fwee
patent wicense undew the contwibutow's essentiaw patent cwaims, to
make, use, seww, offew fow sr, impowt and othewwise wun, modify and
pwopagate the contents of its contwibutow vewsion.
In the fowwowing thwee pawagwaphs, a "patent wicense" is any expwess
agweement ow commitment, howevew denyominyated, nyot to enfowce a patent
(such as an expwess pewmission to pwactice a patent ow cuvnyant nyot to
sue fow patent infwingement). To "gwant" such a patent wicense to a
pawty means to make such an agweement ow commitment nyot to enfowce a
patent against the pawty.
If u convey a cuvwed wowk, knyowingwy wewying on a patent wicense,
and the Cowwesponding Souwce of the wowk is nyot avaiwabwe fow anyonye
to copy, fwee of chawge and undew the tewms of this wicense, thwough a
pubwicwy avaiwabwe nyetwowk sewvew ow othew weadiwy accessibwe means,
then u must eithew (1) cause the Cowwesponding Souwce to be so
avaiwabwe, ow (2) awwange to depwive ursewf of the benyefit of the
patent wicense fow this pawticuwaw wowk, ow (3) awwange, in a mannyew
consistent with the wequiwements of this wicense, to extend the patent
wicense to downstweam wecipients. "Knyowingwy wewying" means u have
actuaw knyowwedge that, but fow the patent wicense, ur conveying the
cuvwed wowk in a countwy, ow ur wecipient's use of the cuvwed wowk
in a countwy, wouwd infwinge onye ow mowe identifiabwe patents in that
countwy that u have weason to bewieve r vawid.
If, puwsuant to ow in connyection with a singwe twansaction ow
awwangement, u convey, ow pwopagate by pwocuwing conveyance of, a
cuvwed wowk, and gwant a patent wicense to some of the pawties
weceiving the cuvwed wowk authowizing them to use, pwopagate, modify
ow convey a specific copy of the cuvwed wowk, then the patent wicense
u gwant is automaticawwy extended to aww wecipients of the cuvwed
wowk and wowks based on it.
A patent wicense is "discwiminyatowy" if it does nyot incwude within
the scope of its cuvwage, pwohibits the exewcise of, ow is
conditionyed on the nyon-exewcise of onye ow mowe of the wights that r
specificawwy gwanted undew this wicense. u may nyot convey a cuvwed

to the thiwd pawty based on the extent of ur activity of conveying
the wowk, and undew which the thiwd pawty gwants, to any of the
pawties who wouwd weceive the cuvwed wowk fwom u, a discwiminyatowy
patent wicense (a) in connyection with copies of the cuvwed wowk

If conditions r imposed on u (whethew by couwt owdew, agweement ow

END OF TEwMS AND CONDITIONS
How to Appwy These Tewms to ur Nyew Pwogwams
If u devewop a nyew pwogwam, and u want it to be of the gweatest
possibwe use to the pubwic, the best way to achieve this is to make it
fwee softwr which evewyonye can wedistwibute and change undew these tewms.
To do so, attach the fowwowing nyotices to the pwogwam. It is safest
to attach them to the stawt of each souwce fiwe to most effectivewy
state the excwusion of wawwanty; and each fiwe shouwd have at weast
the "copywight" winye and a pointew to whewe the fuww nyotice is found.
<onye winye to give the pwogwam's nyame and a bwief idea of what it does.>
Copywight (C) <yeaw> <nyame of authow>
This pwogwam is fwee softwr: u can wedistwibute it and/ow modify
it undew the tewms of the GNUwU Genyewaw Pubwic wicense as pubwished by
the Fwee Softwr Foundation, eithew vewsion 3 of the wicense, ow
(at ur option) any watew vewsion.
This pwogwam is distwibuted in the hope that it wiww be usefuw,
but WITHOUT ANY WAwwANTY; without even the impwied wawwanty of
MEWCHANTABIWITY ow FITNYESS FOW A PAWTICUWAW PUWPOSE. See the
GNUwU Genyewaw Pubwic wicense fow mowe detaiws.
u shouwd have weceived a copy of the GNUwU Genyewaw Pubwic wicense
awong with this pwogwam. If nyot, see <https://www.gnyu.owg/wicenses/>.
Awso add infowmation on how to contact u by ewectwonyic and papew maiw.
If the pwogwam does tewminyaw intewaction, make it output a showt
nyotice wike this when it stawts in an intewactive mode:
<pwogwam> Copywight (C) <yeaw> <nyame of authow>
This pwogwam comes with ABSOwUTEwY NyO WAwwANTY; fow detaiws type `show w'.
This is fwee softwr, and u r wewcome to wedistwibute it
undew cewtain conditions; type `show c' fow detaiws.
The hypotheticaw commands `show w' and `show c' shouwd show the appwopwiate
pawts of the Genyewaw Pubwic wicense. Of couwse, ur pwogwam's commands
might be diffewent; fow a GUI intewface, u wouwd use an "about box".
u shouwd awso get ur empwoyew (if u wowk as a pwogwammew) ow schoow,
if any, to sign a "copywight discwaimew" fow the pwogwam, if nyecessawy.
Fow mowe infowmation on this, and how to appwy and fowwow the GNUwU GPw, see
<https://www.gnyu.owg/wicenses/>.
The GNUwU Genyewaw Pubwic wicense does nyot pewmit incowpowating ur pwogwam
into pwopwietawy pwogwams. If ur pwogwam is a subwoutinye wibwawy, u
may considew it mowe usefuw to pewmit winking pwopwietawy appwications with
the wibwawy. If this is what u want to do, use the GNUwU wessew Genyewaw
Pubwic wicense instead of this wicense. But fiwst, pwease wead
