Ever yone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take awa y your freedom to
share and change it. By contrast, the GNU Gener al Public License is intended
to guarantee your freedom to share and change free software--to make sure
the software is free for all its users. This General Public License applies to most
of the Free Software Foundation’ s software and to any other program whose
author s commit to using it. (Some other Free Software Foundation software
is covered b y the GNU Lesser Gener al Public License instead.) Y ou can apply
it to your programs, too.
When we speak of free software, we are referring to freedom, not price .
Our General Public Licenses are designed to make sure that you ha ve the
freedom to distribute copies of free software (and char ge for this ser vice if
you wish), that you receiv e source code or can get it if you want it, that you
can change the software or use pieces of it in new free programs; and that you
know you can do these things.
T o protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restrictions
translate to cer tain responsibilities for you if y ou distr ibute copies of the
software, or if you modify it. For example , if you distribute copies of such a
program, whether gr atis or for a fee, you must give the recipients all the
rights that you have. Y ou must mak e sure that they , too, receive or can get the
source code. And y ou must show them these terms so they know their r ights.
W e protect your rights with two steps: (1) copyright the software , and (2)
offer you this license which giv es you legal permission to copy , distr ibute and/
or modify the software.
Also, for each author’ s protection and our s, we want to make cer tain that
ever yone understands that there is no war ranty for this free software . If the
software is modified by someone else and passed on, w e want its recipients to
know that what they ha ve is not the original, so that any problems introduced
by others will not reflect on the or iginal author s’ reputations.
Finally , any free program is threatened constantly by software patents. W e wish
to av oid the danger that redistributor s of a free program will individually obtain
patent licenses, in effect making the program proprietar y . T o prevent this, we
hav e made it clear that any patent must be licensed for ev er yone’ s free use or
not licensed at all.
The precise terms and conditions for copying, distribution and modification
follow .
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFIC A TION
0. This License applies to any program or other work which contains a
notice placed by the copyright holder saying it ma y be distributed under
the terms of this Gener al Public License. The “Program”, below , refers to
any such program or work, and a “wor k based on the Program” means
either the Program or any derivative wor k under copyright law: that is to
say , a work containing the Program or a por tion of it, either verbatim or
with modifications and/or translated into another language. (Hereinafter ,
translation is included without limitation in the ter m “modification”.) Each
licensee is addressed as “you”.
Activities other than copying, distribution and modification are not
covered b y this License; they are outside its scope . The act of running the
Program is not restr icted,and the output from the Program is covered
only if its contents constitute a work based on the Progr am (independent
of having been made b y r unning the Program). Whether that is tr ue
depends on what the Program does.
1. Y ou ma y copy and distribute verbatim copies of the Program’s source
code as you receive it, in an y medium, provided that you conspicuously
and appropriately publish on each copy an appropriate copyright notice
and disclaimer of warr anty; keep intact all the notices that 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 Program.
Y ou ma y char ge a fee for the physical act of transferring a copy , and you
may at your option off er war r anty protection in exchange for a fee..
2. Y ou ma y modify your copy or copies of the Program or any por tion of it,
thus forming a wor k based on the Program, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that
you also meet all of these conditions:
a) Y ou m ust cause the modified files to carr y prominent notices stating
that you changed the f iles and the date of any change.
b) Y ou m ust cause any work that you distribute or publish, that in
whole or in par t contains or is der ived from the Program or any
par t thereof, to be licensed as a whole at no charge to all third
par ties under the ter ms of this License .
c) If the modif ied progr am normally reads commands inter actively
when r un, you must cause it, when star ted r unning for such
interactive use in the most ordinar y way , to pr int or display an
announcement including an appropriate copyright notice and a
notice that there is no warr anty (or else, saying that you pro vide a
warr anty) and that user s may redistribute the program under these
conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is inter active but does not normally
print such an announcement, your work based on the Progr am is
not required to print an announcement.)
These requirements apply to the modified w or k as a whole . If identifiable
sections of that work are not der ived from the Program, and can be reasonably
considered independent and separate wor ks in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate wor ks. But when you distribute the same sections as par t of a whole
which is a work based on the Progr am, the distribution of the whole must be
on the terms of this License ,whose permissions for other licensees extend to
the entire whole, and thus to each and ever y par t regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work wr itten entirely by you; rather , the intent is to exercise the right to control
the distribution of der ivative or collective w or ks based on the Progr am.
In addition, mere aggregation of another work not based on the Progr am with
the Program (or with a wor k based on the Program) on a volume of a stor age
or distribution medium does not br ing the other work under the scope of
this License.
3. Y ou ma y copy and distribute the Program (or a wor k based on it, under
Section 2) in object code or executable f or m under the ter ms of Sections
1 and 2 above pro vided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distr ibuted under the terms of
Sections 1 and 2 above on a medium customarily used for software
interchange; or ,
b) Accompany it with a written offer , valid for at least three y ear s, to
give any third par ty , for a charge no more than your cost of physically
performing source distr ibution, a complete machine-readable cop y
of the corresponding source code , to be distr ibuted under the
terms of Sections 1 and 2 above on a medium customarily used for
software interchange; or ,
c) Accompany it with the information you receiv ed as to the offer to
distribute cor responding source code. (This alter native is allowed
only for noncommercial distribution and only if you receiv ed the
program in object code or executable form with such an offer , in
accord with Subsection b above.)
The source code for a work means the preferred for m of the work for making
modifications to it. For an executab le wor k, complete source code means all the
source code for all modules it contains, plus any associated interface def inition
files, plus the scripts used to control compilation and installation of the executable.
Howev er , as a special exception, the source code distr ibuted need not include
anything that is normally distributed (in either source or binar y form) with the
major components (compiler , kernel, and so on) of the oper ating system on which
the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by off er ing access to copy
from a designated place, then offer ing equivalent access to copy the source code
from the same place counts as distribution of the source code , even though
third par ties are not compelled to copy the source along with the object code .
4. Y ou may not copy , modify , sublicense, or distribute the Progr am except
as expressly provided under this License. Any attempt otherwise to copy ,
modify , sublicense or distribute the Program is void, and will automatically
terminate your rights under this License . However , par ties who have
received copies, or rights, from you under this License will not hav e their
licenses terminated so long as such par ties remain in full compliance.
5. Y ou are not required to accept this License, since you hav e not signed
it. Howev er , nothing else grants you permission to modify or distr ibute
