W e p rotect your righ ts with two steps: (1) copyright the
soware, a nd (2) oer you this license which gives y ou legal
permission to cop y , distribute a nd/or modify the soware.
Also, fo r each author ’ s pr otection and ours, w e want to make
certain that everyone understands tha t there is no warran ty for
this free soware. I f the soware is modied by someone e lse
and passed on, we wan t its recip ients to know tha t what they
have is n ot the original, so that any p roblems in troduced by
others will not reect on the o riginal authors ’ repu tations.
Finally , an y free program is threa tened constan tly by soware

making the program p roprietary . T o prevent this, we ha ve made

TERMS AND CONDITIONS FO R COPYING,
DISTRIB UTION AND MODIFI CA TION
is License applies t o any pr ogram or other work which
contain s a notice placed by the copyrigh t holder saying it ma y
be distributed under the terms o f this General Public License.
e ‘Pr ogram ’ , belo w , refer s to any such p rogram or wor k, and
a ‘work based on the P rogram ’ mean s either the Program or
any deriva tive work under co pyright law: that is to say , a work
containin g the Program or a portion of i t, either verbatim or
with modications a nd/or translated in to another langua ge.
(Her einaer , transla tion is included withou t limitation in the
term ‘modica tion ’ .) Eac h licensee is addressed as ‘you ’ .
Activities o ther than copying, distribu tion and modication ar e
not cov ered by this License; they are outside i ts scope. e act
of running the Program i s not restricted, and the ou tput from
the Program is co vered only if its co ntents co nstitute a w ork
based on the Program (independen t of having been made by
running the Program). Wh ether that is true depends on what
the Program does.

1. Y ou may cop y and distribute v erbatim copies of the P rogram ’ s
source code as you r eceive it, in an y medium, provided tha t
you con spicuously and a ppro priately pu blish on each copy
an ap propria te copyright notice a nd disclaimer of warran ty ;
keep intact all the notices that r efer to this License and to
the absence of an y warranty; and give an y other recipien ts
of the Progra m a copy of this License along with the
Program.
Y ou may cha rge a fee for the ph ysical act of transferring a
copy , and you may a t your option o er warranty pr otection
in exchang e for a fee.
2. Y ou may modify your cop y or copies of the P rogram or an y
portion of it, th us forming a work based on the Pr ogram,
and cop y and distribute suc h modications or wo rk under
the terms of Section 1 above, p rovided that yo u also meet
all of these conditions:
a). Y o u must cau se the modie d les to carry prominent
notices stating tha t you chang ed the les and the date of
any change.
b). Y ou must ca use any wor k that you distribu te or publish,
that in whole or in pa rt contains or is deriv ed from the
Program o r any part thereof, t o be licensed as a w hole at n o
charge t o all third parties under the terms of this License.
c). I f the modied program normally reads co mmands
interactivel y when run, you must cause i t, when started
running for such in teractive use in the most ordina r y
way , t o print or disp lay an announcemen t including a n
app ropriat e copyright notice and a n otice that there is
no warranty (o r else, saying that yo u provide a warra nty)
and that users ma y redistribute the p rogram under these
condition s, and telling the user how to view a cop y of this
License. (Exception: if the Pr ogram itself is interactive
but does not no rmally print such an a nnouncement, yo ur
work based on the Pr ogram is not requir ed to print an
announcemen t.)
ese requiremen ts appl y to the modied work as a whole.
If identiab le sect ions of tha t work ar e not derived from the
Program, an d can be reasonably con sidered independent
and separate w orks in themselves, then this License, and i ts
terms, do not a pply to those sections when you distribu te
them as separate wo rks. But when you distrib ute the same
sections as part of a whole which is a work based on the
Program, the distrib ution of the whole mus t be on the
terms of this License, whose permissions fo r other licensees
extend to the entir e whole, and thus to each a nd ever y part
regardless o f who wrote it.
us, it i s not the inten t of this section to claim rights or
cont est your rights to wo rk written entirel y by you; ra ther ,
the inten t is to exercise the right to con trol the distributio n
of derivativ e or collective works based on the Pr ogram.
In addition, m ere aggregation o f another work no t based
on the Progra m with the Program (or with a wo rk based
on the Progra m) on a volume of a s torage or distrib ution
medium does not bring the o ther work under the scope of
this License.
3. Y ou may cop y and distribute the P rogram (or a wor k based on
it, under Section 2) in object code or executable fo rm under
the terms of Sections 1 and 2 abov e provided tha t you also
do one of the fo llowing:
a). A ccom pany it wi th the complete corr esponding machine-
readable source code, which m ust be distributed under the
terms of Sections 1 and 2 abo ve on a medium customa rily
used for soware in terchan ge; or ,
b). Acco mpany i t with a written oer , valid f or at least three
years, to give a ny third party , fo r a charge no mo re than
your cost o f physically performing source dis tribution,
a comp lete machine-readable cop y of the correspondin g
source code, to be distribut ed under the terms of Sections
1 and 2 abov e on a medium customarily used fo r soware
inter change; or ,
c). A ccompa ny it with the info rmation you recei ved as to
the oer to distrib ute correspondin g source code. (is
alternativ e is allowed only for no ncommercial distribu tion
and only if yo u received the program in o bject code
or executable f orm with such an oer , in acco rd with
Subsection b above.)
e source code for a w ork means the pr eferred form of
the work fo r making modications to it. F or an executable
work, co mplete source code means all the sour ce code
for all modules it co ntains, plus a ny associated int erface
denition les, plu s the scr ipts used to con trol com pilation
and installation o f the executable. Ho wever , as a special
exception, the sour ce code distributed need not include
anything tha t is normally distribut ed (in either source
or bina r y form) with the majo r componen ts (compiler ,
kernel, and so on) o f the operating system on which the
executable runs, unless that co mponent i tself accompanies
the executable.
If distribu tion of executable or o bject code is made by
oering access to co py from a designa ted place, then
oering equivalen t access to copy the sour ce code from the
same place coun ts as distribution of the sour ce code, even
though third parties are not co mpelled to copy the sour ce
along with the object code.
4. Y ou may not co py , modify , sublicen se, or distribute the
Program excep t as expressly p rovided under this License.
Anya ttempt o ther wise to copy , m odif y , sublicen se or
distribute the P rogram is void, an d will automa tically
terminate y our rights under this License. Ho wever , parties
who have r eceived copies, or rights, fro m you under this
License will not have their licenses termina ted so long as
such parties remain in full com pliance.
5. Y ou are not r equired to accept this License, since yo u have not
signed it. Ho wever , nothing else gran ts you permission to
modify or distribute the Pr ogram or its derivativ e works.
ese actions are p rohibited b y law if you do no t accept
this License. erefor e, by modifying or distributin g the
Program (o r any wor k based on the Program), you indica te
your acceptan ce of this License to do so, and all its terms
and condi tions for cop ying, distributing or m odif ying the
Program o r works based on it.
6. Each time you redistribu te the Program (or a ny work based
on the Progra m), the recipient a utoma tically receives a
license from the original licensor to co py , distribu te or
modify the Program subject to these terms and con ditions.
Y ou may not im pose any further restrictions on the
recipien ts’ ex ercise of the rights grant ed herein. Y ou are not
responsib le for enfor cing complian ce by third parties to
this License.
7. If, as a co nsequence of a court judgment o r allegation of paten t
infringement or f or any o ther reason (not limited to
paten t issues), condition s are imposed on you (whether b y
court order , a greement or otherwise) that con tradict t he
condition s of this License, they do not excuse you from the
condition s of this License. If you ca nnot distribute so as to
satisfy simultaneou sly your obliga tions under this License
and an y other pertinent obligation s, then as a consequence
you ma y not distribute the Pr ogram at all. Fo r example, if a
paten t license would not permit ro yalty-free redistribution
of the Progra m by all those who receive copies directly or
indirectly through yo u, then the only way you co uld satisfy
both it and this License would be to r efrain entirely from
distribution o f the Program. If an y portion of this section
is held invalid o r unenforceable under a ny particular
circumstance, the balance o f the sec tion is int ended to
app ly and the section as a whole is intended to a pply in
other circumstances. I t is not the p urpos e of this section to
induce you t o infringe any pat ents or other pr operty right
claims or t o contest validity o f any such cla ims; this sect ion
has the sole purpose of prot ecting the integrity of the free
soware distribu tion system, which is imp lemented by
public license practices. M any people ha ve made generous

Everyone is permitt ed to copy and distrib ute verbatim cop ies of
this license document, but ch anging it is not allo wed.
Preamble
e licenses for most so ware are designed to take a way your
freedom to shar e and change i t. By contrast, the GNU General
Public License is inten ded to guarantee yo ur freedom to share
and chan ge free soware--to make sur e the soware is free for
all its users. is General Public License app lies to most of the
Free Sowar e Foundatio n ’ s s oware a nd to any o ther program
whose author s commit to using it. (Some o ther Free Soware
Founda tion soware is co vered by the GNU Lesser General
Public License instead.) Y ou can a pply it to y our programs, t oo.
When we speak of free sowar e, we are ref erring to freedom,
not price. Our General Public Licenses ar e designed to make
sure that y ou have the freedom to di stribute copies o f free
soware (an d charge for this service if you wish), that y ou
receive sour ce code or can get it if you wa nt it, that y ou can
change the so ware or use pieces of i t in new free programs;
and that y ou know you can do these things.
T o p rotect your righ ts, we need to make restrictions that f orbid
any one to deny y ou these rights or to ask you t o surrender the
rights. ese restrictions transla te to certain responsib ilities for
you if yo u distribute copies o f the soware, or if y ou modify
it. Fo r example, if yo u distribute cop ies of such a progra m,
whether gratis or fo r a fee, you mus t give the recipien ts all the
rights that yo u have. Y ou m ust make sure that they , t oo, receive
or can get the sour ce code. And you must s how them these
terms so they know their rights.
of that syst em; it is up to the au thor/donor to decide if
he or she is willing to dis tribute soware thro ugh any
other system and a licen see cannot impose that choice .
is section is intended to make tho roughly clear what is
believed to be a consequence of the res t of this License.
8. If the distribu tion and/or use of the Pr ogram is restricted
in certain countries either b y patents or b y copyrighted
interfaces, the original cop yright holder who places
the Program under this License ma y add an explicit
geographical distribu tion limitation exc luding those
countries, so that distrib ution is permitted only in o r
among co untries not thus exc luded. In such case, this
License incorporates the limi tation as if written in the body
of this License.
9. e Free Sowar e Founda tion may publis h revised and/or new
versions o f the General Public License from time to time.
Such new versio ns will be simil ar in spiri t to the present
version, b ut may dier in detail to addr ess new problems
or concerns. Each ver sion is given a distinguishing v ersion
number . I f the Program species a version n umber of this
License which applies t o it and ‘ an y later versio n ’ , y ou have
the option o f following the terms and co nditions either o f
that versio n or of an y later version p ublished by the Fr ee
Soware F oundation. If the P rogram does not specify
a version n umber of this License, you ma y choose any
version ever p ublished by the Fr ee Soware Founda tion.
10. I f you wish to incorpora te parts of the Program in to other
free programs whose distrib ution condition s are dieren t,
write to the au thor to ask for permissio n. For soware
which is copyright ed by the Free Soware F oundation,
write to the Fr ee Soware Founda tion; we sometimes make
exceptions f or this. Our decision will be guided by the two
goals of pr eser ving the free status of all deriva tives of our
free soware and o f promo ting the sharing and reuse o f
soware generally .

Ho w to Ap ply ese T erm s to Y our New Program s
If you deve lop a new program, and y ou want it t o be of the
greatest possib le use to the public, the best way to achieve this
is to make it free sowa re which ever yone can r edistribute and
change un der these terms.
T o do so , attach the f ollowing notices to the pr ogram. It i s safest
to attach them t o the start of each source le to most eectively
conv ey the exclusion of wa rranty; and each le should have a t
least the ‘ co pyright’ line a nd a pointer to where the full notice
is found.
