GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for software and
other kinds of works.
The licenses for most software and other practical works are designed to
take away your freedom to share and change the works. By contrast, the GNU
General Public License is intended to guarantee your freedom to share and change
all versions of a program--to make sure it remains free software for all its
users. We, the Free Software Foundation, use the GNU General Public License for
most of our software; it applies also to any other work released this way by its
authors. You 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 have the freedom to
distribute copies of free software (and charge for them if you wish), that you
receive 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.
To protect your rights, we need to prevent others from denying you these
rights or asking you to surrender the rights. Therefore, you have certain
responsibilities if you distribute copies of the software, or if you modify it:
responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must pass on to the recipients the same freedoms that you
received. You must make sure that they, too, receive or can get the source code.
And you must show them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1)
assert copyright on the software, and (2) offer you this License giving you
legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains that
there is no warranty for this free software. For both users' and authors' sake,
the GPL requires that modified versions be marked as changed, so that their
problems will not be attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modified
versions of the software inside them, although the manufacturer can do so. This
is fundamentally incompatible with the aim of protecting users' freedom to
change the software. The systematic pattern of such abuse occurs in the area of
products for individuals to use, which is precisely where it is most
unacceptable. Therefore, we have designed this version of the GPL to prohibit
the practice for those products. If such problems arise substantially in other
domains, we stand ready to extend this provision to those domains in future
versions of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents. States
should not allow patents to restrict development and use of software on
general-purpose computers, but in those that do, we wish to avoid the special
danger that patents applied to a free program could make it effectively
proprietary. To prevent this, the GPL assures that patents cannot be used to
render the program non-free.
The precise terms and conditions for copying, distribution and modification
follow.
TERMS AND CONDITIONS
0. Definitions.
---------------
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
“The Program” refers to any copyrightable work licensed under this License.
Each licensee is addressed as “you”. “Licensees” and “recipients” may be
individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a
fashion requiring copyright permission, other than the making of an exact copy.
The resulting work is called a “modified version” of the earlier work or a work
“based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the
Program.
To “propagate” a work means to do anything with it that, without permission,
would make you directly or secondarily liable for infringement under applicable
copyright law, except executing it on a computer or modifying a private copy.
Propagation includes copying, distribution (with or without modification),
making available to the public, and in some countries other activities as well.
To “convey” a work means any kind of propagation that enables other parties
to make or receive copies. Mere interaction with a user through a computer
network, with no transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the
extent that it includes a convenient and prominently visible feature that (1)
displays an appropriate copyright notice, and (2) tells the user that there is
no warranty for the work (except to the extent that warranties are provided),
that licensees may convey the work under this License, and how to view a copy of
this License. If the interface presents a list of user commands or options, such
as a menu, a prominent item in the list meets this criterion.
1. Source Code.
---------------
The “source code” for a work means the preferred form of the work for making
modifications to it. “Object code” means any non-source form of a work.
A “Standard Interface” means an interface that either is an official
standard defined by a recognized standards body, or, in the case of interfaces
specified for a particular programming language, one that is widely used among
developers working in that language.
The “System Libraries” of an executable work include anything, other than
the work as a whole, that (a) is included in the normal form of packaging a
Major Component, but which is not part of that Major Component, and (b) serves
only to enable use of the work with that Major Component, or to implement a
Standard Interface for which an implementation is available to the public in
source code form. A “Major Component”, in this context, means a major essential
component (kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to produce the
work, or an object code interpreter used to run it.
The “Corresponding Source” for a work in object code form means all the
source code needed to generate, install, and (for an executable work) run the
object code and to modify the work, including scripts to control those
activities. However, it does not include the work's System Libraries, or
general-purpose tools or generally available free programs which are used
unmodified in performing those activities but which are not part of the work.
For example, Corresponding Source includes interface definition files associated
with source files for the work, and the source code for shared libraries and
dynamically linked subprograms that the work is specifically designed to
require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate
automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
---------------------
All rights granted under this License are granted for the term of copyright
on the Program, and are irrevocable provided the stated conditions are met. This
License explicitly affirms your unlimited permission to run the unmodified
Program. The output from running a covered work is covered by this License only
if the output, given its content, constitutes a covered work. This License
acknowledges your rights of fair use or other equivalent, as provided by
copyright law.
You may make, run and propagate covered works that you do not convey,
without conditions so long as your license otherwise remains in force. You may
convey covered works to others for the sole purpose of having them make
modifications exclusively for you, or provide you with facilities for running
those works, provided that you comply with the terms of this License in
conveying all material for which you do not control copyright. Those thus making
or running the covered works for you must do so exclusively on your behalf,
under your direction and control, on terms that prohibit them from making any
copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the
conditions stated below. Sublicensing is not allowed; section 10 makes it
unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
--------------------------------------------------------------
No covered work shall be deemed part of an effective technological measure
under any applicable law fulfilling obligations under article 11 of the WIPO
copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention is
effected by exercising rights under this License with respect to the covered
work, and you disclaim any intention to limit operation or modification of the
work as a means of enforcing, against the work's users, your or third parties'
legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
-----------------------------
You may convey verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish on
each copy an appropriate copyright notice; keep intact all notices stating that
this License and any non-permissive terms added in accord with section 7 apply
to the code; keep intact all notices of the absence of any warranty; and give
all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you
may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
--------------------------------------
You may convey a work based on the Program, or the modifications to produce
it from the Program, in the form of source code under the terms of section 4,
provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and
giving a relevant date.
b) The work must carry prominent notices stating that it is released under
this License and any conditions added under section 7. This requirement
modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to
anyone who comes into possession of a copy. This License will therefore
apply, along with any applicable section 7 additional terms, to the whole
of the work, and all its parts, regardless of how they are packaged. This
License gives no permission to license the work in any other way, but it
does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your work need
not make them do so.
A compilation of a covered work with other separate and independent works,
which are not by their nature extensions of the covered work, and which are not
combined with it such as to form a larger program, in or on a volume of a
storage or distribution medium, is called an “aggregate” if the compilation and
its resulting copyright are not used to limit the access or legal rights of the
compilation's users beyond what the individual works permit. Inclusion of a
covered work in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
------------------------------
You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by the Corresponding Source
fixed on a durable physical medium customarily used for software
interchange.
b) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by a written offer, valid
for at least three years and valid for as long as you offer spare parts
or customer support for that product model, to give anyone who possesses
the object code either (1) a copy of the Corresponding Source for all the
software in the product that is covered by this License, on a durable
physical medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this conveying of
source, or (2) access to copy the Corresponding Source from a network
server at no charge.
c) Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is allowed
only occasionally and noncommercially, and only if you received the
object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis
or for a charge), and offer equivalent access to the Corresponding Source
in the same way through the same place at no further charge. You need not
require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the
Corresponding Source may be on a different server (operated by you or a
third party) that supports equivalent copying facilities, provided you
maintain clear directions next to the object code saying where to find
the Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is available
for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you
inform other peers where the object code and Corresponding Source of the
work are being offered to the general public at no charge under
subsection 6d.
A separable portion of the object code, whose source code is excluded from
the Corresponding Source as a System Library, need not be included in conveying
the object code work.
A “User Product” is either (1) a “consumer product”, which means any
tangible personal property which is normally used for personal, family, or
household purposes, or (2) anything designed or sold for incorporation into a
dwelling. In determining whether a product is a consumer product, doubtful cases
shall be resolved in favor of coverage. For a particular product received by a
particular user, “normally used” refers to a typical or common use of that class
of product, regardless of the status of the particular user or of the way in
which the particular user actually uses, or expects or is expected to use, the
product. A product is a consumer product regardless of whether the product has
substantial commercial, industrial or non-consumer uses, unless such uses
represent the only significant mode of use of the product.
“Installation Information” for a User Product means any methods, procedures,
authorization keys, or other information required to install and execute
modified versions of a covered work in that User Product from a modified version
of its Corresponding Source. The information must suffice to ensure that the
continued functioning of the modified object code is in no case prevented or
interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as part of a
transaction in which the right of possession and use of the User Product is
transferred to the recipient in perpetuity or for a fixed term (regardless of
how the transaction is characterized), the Corresponding Source conveyed under
this section must be accompanied by the Installation Information. But this
requirement does not apply if neither you nor any third party retains the
ability to install modified object code on the User Product (for example, the
work has been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates for a
work that has been modified or installed by the recipient, or for the User
Product in which it has been modified or installed. Access to a network may be
denied when the modification itself materially and adversely affects the
operation of the network or violates the rules and protocols for communication
across the network.
Corresponding Source conveyed, and Installation Information provided, in
accord with this section must be in a format that is publicly documented (and
with an implementation available to the public in source code form), and must
require no special password or key for unpacking, reading or copying.
7. Additional Terms.
--------------------
“Additional permissions” are terms that supplement the terms of this License
by making exceptions from one or more of its conditions. Additional permissions
that are applicable to the entire Program shall be treated as though they were
included in this License, to the extent that they are valid under applicable
law. If additional permissions apply only to part of the Program, that part may
be used separately under those permissions, but the entire Program remains
governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any
additional permissions from that copy, or from any part of it. (Additional
permissions may be written to require their own removal in certain cases when
you modify the work.) You may place additional permissions on material, added by
you to a covered work, for which you have or can give appropriate copyright
permission.
Notwithstanding any other provision of this License, for material you add to
a covered work, you may (if authorized by the copyright holders of that
material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of
sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices
displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in reasonable
ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors
of the material; or
e) Declining to grant rights under trademark law for use of some trade
names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by
anyone who conveys the material (or modified versions of it) with
contractual assumptions of liability to the recipient, for any liability
that these contractual assumptions directly impose on those licensors and
authors.
All other non-permissive additional terms are considered “further
restrictions” within the meaning of section 10. If the Program as you received
it, or any part of it, contains a notice stating that it is governed by this
License along with a term that is a further restriction, you may remove that
term. If a license document contains a further restriction but permits
relicensing or conveying under this License, you may add to a covered work
material governed by the terms of that license document, provided that the
further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must
place, in the relevant source files, a statement of the additional terms that
apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of
a separately written license, or stated as exceptions; the above requirements
apply either way.
8. Termination.
---------------
You may not propagate or modify a covered work except as expressly provided
under this License. Any attempt otherwise to propagate or modify it is void, and
will automatically terminate your rights under this License (including any
patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from
a particular copyright holder is reinstated (a) provisionally, unless and until
the copyright holder explicitly and finally terminates your license, and (b)
permanently, if the copyright holder fails to notify you of the violation by
some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated
permanently if the copyright holder notifies you of the violation by some
reasonable means, this is the first time you have received notice of violation
of this License (for any work) from that copyright holder, and you cure the
violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under this
License. If your rights have been terminated and not permanently reinstated, you
do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
---------------------------------------------
You are not required to accept this License in order to receive or run a
copy of the Program. Ancillary propagation of a covered work occurring solely as
a consequence of using peer-to-peer transmission to receive a copy likewise does
not require acceptance. However, nothing other than this License grants you
permission to propagate or modify any covered work. These actions infringe
copyright if you do not accept this License. Therefore, by modifying or
propagating a covered work, you indicate your acceptance of this License to
do so.
10. Automatic Licensing of Downstream Recipients.
-------------------------------------------------
Each time you convey a covered work, the recipient automatically receives a
license from the original licensors, to run, modify and propagate that work,
subject to this License. You are not responsible for enforcing compliance by
third parties with this License.
An “entity transaction” is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered work results
from an entity transaction, each party to that transaction who receives a copy
of the work also receives whatever licenses to the work the party's predecessor
in interest had or could give under the previous paragraph, plus a right to
possession of the Corresponding Source of the work from the predecessor in
interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights
granted or affirmed under this License. For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted under this
License, and you may not initiate litigation (including a cross-claim or
counterclaim in a lawsuit) alleging that any patent claim is infringed by
making, using, selling, offering for sale, or importing the Program or any
portion of it.
11. Patents.
------------
A “contributor” is a copyright holder who authorizes use under this License
of the Program or a work on which the Program is based. The work thus licensed
is called the contributor's “contributor version”.
A contributor's “essential patent claims” are all patent claims owned or
controlled by the contributor, whether already acquired or hereafter acquired,
that would be infringed by some manner, permitted by this License, of making,
using, or selling its contributor version, but do not include claims that would
be infringed only as a consequence of further modification of the contributor
version. For purposes of this definition, “control” includes the right to grant
patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent
license under the contributor's essential patent claims, to make, use, sell,
offer for sale, import and otherwise run, modify and propagate the contents of
its contributor version.
In the following three paragraphs, a “patent license” is any express
agreement or commitment, however denominated, not to enforce a patent (such as
an express permission to practice a patent or covenant not to sue for patent
infringement). To “grant” such a patent license to a party means to make such an
agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free of
charge and under the terms of this License, through a publicly available network
server or other readily accessible means, then you must either (1) cause the
Corresponding Source to be so available, or (2) arrange to deprive yourself of
the benefit of the patent license for this particular work, or (3) arrange, in a
manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. “Knowingly relying” means you have actual
knowledge that, but for the patent license, your conveying the covered work in a
country, or your recipient's use of the covered work in a country, would
infringe one or more identifiable patents in that country that you have reason
to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work, and grant a
patent license to some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of the covered work,
then the patent license you grant is automatically extended to all recipients of
the covered work and works based on it.
A patent license is “discriminatory” if it does not include within the scope
of its coverage, prohibits the exercise of, or is conditioned on the
non-exercise of one or more of the rights that are specifically granted under
this License. You may not convey a covered work if you are a party to an
arrangement with a third party that is in the business of distributing software,
under which you make payment to the third party based on the extent of your
activity of conveying the work, and under which the third party grants, to any
of the parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work conveyed by you
(or copies made from those copies), or (b) primarily for and in connection with
specific products or compilations that contain the covered work, unless you
entered into that arrangement, or that patent license was granted, prior to
28 March 2007.
Nothing in this License shall be construed as excluding or limiting any
implied license or other defenses to infringement that may otherwise be
available to you under applicable patent law.
12. No Surrender of Others' Freedom.
------------------------------------
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not excuse
you from the conditions of this License. If you cannot convey a covered work so
as to satisfy simultaneously your obligations under this License and any other
pertinent obligations, then as a consequence you may not convey it at all. For
example, if you agree to terms that obligate you to collect a royalty for
further conveying from those to whom you convey the Program, the only way you
could satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
13. Use with the GNU Affero General Public License.
---------------------------------------------------
Notwithstanding any other provision of this License, you have permission to
link or combine any covered work with a work licensed under version 3 of the GNU
Affero General Public License into a single combined work, and to convey the
resulting work. The terms of this License will continue to apply to the part
which is the covered work, but the special requirements of the GNU Affero
General Public License, section 13, concerning interaction through a network
will apply to the combination as such.
14. Revised Versions of this License.
-------------------------------------
The Free Software Foundation may publish revised and/or new versions of the
GNU General Public License from time to time. Such new versions will be similar
in spirit to the present version, but may differ in detail to address new
problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies that a certain numbered version of the GNU General Public License
“or any later version” applies to it, you have the option of following the terms
and conditions either of that numbered version or of any later version published
by the Free Software Foundation. If the Program does not specify a version
number of the GNU General Public License, you may choose any version ever
published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of
the GNU General Public License can be used, that proxy's public statement of
acceptance of a version permanently authorizes you to choose that version for
the Program.
Later license versions may give you additional or different permissions.
However, no additional obligations are imposed on any author or copyright holder
as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
---------------------------
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
----------------------------
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY
TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
-----------------------------------------
If the disclaimer of warranty and limitation of liability provided above
cannot be given local legal effect according to their terms, reviewing courts
shall apply local law that most closely approximates an absolute waiver of all
civil liability in connection with the Program, unless a warranty or assumption
of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible
use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively state the
exclusion of warranty; and each file should have at least the “copyright” line
and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short notice
like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands might be
different; for a GUI interface, you would use an “about box”.
You should also get your employer (if you work as a programmer) or school,
if any, to sign a “copyright disclaimer” for the program, if necessary. For more
information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General Public
License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
