GNU GENERAL PUBLIC LICENSE |
||||
Version 3, 29 June 2007 |
||||
|
||||
Copyright (C) 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 |

|
||||
Basic Installation |
||||
================== |
||||
|
||||
Briefly, the shell commands `./configure; make; make install' should |
||||
configure, build, and install this package. The following |
||||
more-detailed instructions are generic; see the `README' file for |
||||
instructions specific to this package. Some packages provide this |
||||
`INSTALL' file but do not implement all of the features documented |
||||
below. The lack of an optional feature in a given package is not |
||||
necessarily a bug. More recommendations for GNU packages can be found |
||||
in *note Makefile Conventions: (standards)Makefile Conventions. |
||||
|
||||
The `configure' shell script attempts to guess correct values for |
||||
various system-dependent variables used during compilation. It uses |
||||
those values to create a `Makefile' in each directory of the package. |
||||
It may also create one or more `.h' files containing system-dependent |
||||
definitions. Finally, it creates a shell script `config.status' that |
||||
you can run in the future to recreate the current configuration, and a |
||||
file `config.log' containing compiler output (useful mainly for |
||||
debugging `configure'). |
||||
|
||||
It can also use an optional file (typically called `config.cache' |
||||
and enabled with `--cache-file=config.cache' or simply `-C') that saves |
||||
the results of its tests to speed up reconfiguring. Caching is |
||||
disabled by default to prevent problems with accidental use of stale |
||||
cache files. |
||||
|
||||
If you need to do unusual things to compile the package, please try |
||||
to figure out how `configure' could check whether to do them, and mail |
||||
diffs or instructions to the address given in the `README' so they can |
||||
be considered for the next release. If you are using the cache, and at |
||||
some point `config.cache' contains results you don't want to keep, you |
||||
may remove or edit it. |
||||
|
||||
The file `configure.ac' (or `configure.in') is used to create |
||||
`configure' by a program called `autoconf'. You need `configure.ac' if |
||||
you want to change it or regenerate `configure' using a newer version |
||||
of `autoconf'. |
||||
|
||||
The simplest way to compile this package is: |
||||
|
||||
1. `cd' to the directory containing the package's source code and type |
||||
`./configure' to configure the package for your system. |
||||
|
||||
Running `configure' might take a while. While running, it prints |
||||
some messages telling which features it is checking for. |
||||
|
||||
2. Type `make' to compile the package. |
||||
|
||||
3. Optionally, type `make check' to run any self-tests that come with |
||||
the package, generally using the just-built uninstalled binaries. |
||||
|
||||
4. Type `make install' to install the programs and any data files and |
||||
documentation. When installing into a prefix owned by root, it is |
||||
recommended that the package be configured and built as a regular |
||||
user, and only the `make install' phase executed with root |
||||
privileges. |
||||
|
||||
5. Optionally, type `make installcheck' to repeat any self-tests, but |
||||
this time using the binaries in their final installed location. |
||||
This target does not install anything. Running this target as a |
||||
regular user, particularly if the prior `make install' required |
||||
root privileges, verifies that the installation completed |
||||
correctly. |
||||
|
||||
6. You can remove the program binaries and object files from the |
||||
source code directory by typing `make clean'. To also remove the |
||||
files that `configure' created (so you can compile the package for |
||||
a different kind of computer), type `make distclean'. There is |
||||
also a `make maintainer-clean' target, but that is intended mainly |
||||
for the package's developers. If you use it, you may have to get |
||||
all sorts of other programs in order to regenerate files that came |
||||
with the distribution. |
||||
|
||||
7. Often, you can also type `make uninstall' to remove the installed |
||||
files again. In practice, not all packages have tested that |
||||
uninstallation works correctly, even though it is required by the |
||||
GNU Coding Standards. |
||||
|
||||
8. Some packages, particularly those that use Automake, provide `make |
||||
distcheck', which can by used by developers to test that all other |
||||
targets like `make install' and `make uninstall' work correctly. |
||||
This target is generally not run by end users. |
||||
|
||||
Compilers and Options |
||||
===================== |
||||
|
||||
Some systems require unusual options for compilation or linking that |
||||
the `configure' script does not know about. Run `./configure --help' |
||||
for details on some of the pertinent environment variables. |
||||
|
||||
You can give `configure' initial values for configuration parameters |
||||
by setting variables in the command line or in the environment. Here |
||||
is an example: |
||||
|
||||
./configure CC=c99 CFLAGS=-g LIBS=-lposix |
||||
|
||||
*Note Defining Variables::, for more details. |
||||
|
||||
Compiling For Multiple Architectures |
||||
==================================== |
||||
|
||||
You can compile the package for more than one kind of computer at the |
||||
same time, by placing the object files for each architecture in their |
||||
own directory. To do this, you can use GNU `make'. `cd' to the |
||||
directory where you want the object files and executables to go and run |
||||
the `configure' script. `configure' automatically checks for the |
||||
source code in the directory that `configure' is in and in `..'. This |
||||
is known as a "VPATH" build. |
||||
|
||||
With a non-GNU `make', it is safer to compile the package for one |
||||
architecture at a time in the source code directory. After you have |
||||
installed the package for one architecture, use `make distclean' before |
||||
reconfiguring for another architecture. |
||||
|
||||
On MacOS X 10.5 and later systems, you can create libraries and |
||||
executables that work on multiple system types--known as "fat" or |
||||
"universal" binaries--by specifying multiple `-arch' options to the |
||||
compiler but only a single `-arch' option to the preprocessor. Like |
||||
this: |
||||
|
||||
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ |
||||
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ |
||||
CPP="gcc -E" CXXCPP="g++ -E" |
||||
|
||||
This is not guaranteed to produce working output in all cases, you |
||||
may have to build one architecture at a time and combine the results |
||||
using the `lipo' tool if you have problems. |
||||
|
||||
Installation Names |
||||
================== |
||||
|
||||
By default, `make install' installs the package's commands under |
||||
`/usr/local/bin', include files under `/usr/local/include', etc. You |
||||
can specify an installation prefix other than `/usr/local' by giving |
||||
`configure' the option `--prefix=PREFIX', where PREFIX must be an |
||||
absolute file name. |
||||
|
||||
You can specify separate installation prefixes for |
||||
architecture-specific files and architecture-independent files. If you |
||||
pass the option `--exec-prefix=PREFIX' to `configure', the package uses |
||||
PREFIX as the prefix for installing programs and libraries. |
||||
Documentation and other data files still use the regular prefix. |
||||
|
||||
In addition, if you use an unusual directory layout you can give |
||||
options like `--bindir=DIR' to specify different values for particular |
||||
kinds of files. Run `configure --help' for a list of the directories |
||||
you can set and what kinds of files go in them. In general, the |
||||
default for these options is expressed in terms of `${prefix}', so that |
||||
specifying just `--prefix' will affect all of the other directory |
||||
specifications that were not explicitly provided. |
||||
|
||||
The most portable way to affect installation locations is to pass the |
||||
correct locations to `configure'; however, many packages provide one or |
||||
both of the following shortcuts of passing variable assignments to the |
||||
`make install' command line to change installation locations without |
||||
having to reconfigure or recompile. |
||||
|
||||
The first method involves providing an override variable for each |
||||
affected directory. For example, `make install |
||||
prefix=/alternate/directory' will choose an alternate location for all |
||||
directory configuration variables that were expressed in terms of |
||||
`${prefix}'. Any directories that were specified during `configure', |
||||
but not in terms of `${prefix}', must each be overridden at install |
||||
time for the entire installation to be relocated. The approach of |
||||
makefile variable overrides for each directory variable is required by |
||||
the GNU Coding Standards, and ideally causes no recompilation. |
||||
However, some platforms have known limitations with the semantics of |
||||
shared libraries that end up requiring recompilation when using this |
||||
method, particularly noticeable in packages that use GNU Libtool. |
||||
|
||||
The second method involves providing the `DESTDIR' variable. For |
||||
example, `make install DESTDIR=/alternate/directory' will prepend |
||||
`/alternate/directory' before all installation names. The approach of |
||||
`DESTDIR' overrides is not required by the GNU Coding Standards, and |
||||
does not work on platforms that have drive letters. On the other hand, |
||||
it does better at avoiding recompilation issues, and works well even |
||||
when some directory options were not specified in terms of `${prefix}' |
||||
at `configure' time. |
||||
|
||||
Optional Features |
||||
================= |
||||
|
||||
If the package supports it, you can cause programs to be installed |
||||
with an extra prefix or suffix on their names by giving `configure' the |
||||
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. |
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to |
||||
`configure', where FEATURE indicates an optional part of the package. |
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE |
||||
is something like `gnu-as' or `x' (for the X Window System). The |
||||
`README' should mention any `--enable-' and `--with-' options that the |
||||
package recognizes. |
||||
|
||||
For packages that use the X Window System, `configure' can usually |
||||
find the X include and library files automatically, but if it doesn't, |
||||
you can use the `configure' options `--x-includes=DIR' and |
||||
`--x-libraries=DIR' to specify their locations. |
||||
|
||||
Some packages offer the ability to configure how verbose the |
||||
execution of `make' will be. For these packages, running `./configure |
||||
--enable-silent-rules' sets the default to minimal output, which can be |
||||
overridden with `make V=1'; while running `./configure |
||||
--disable-silent-rules' sets the default to verbose, which can be |
||||
overridden with `make V=0'. |
||||
|
||||
Particular systems |
||||
================== |
||||
|
||||
On HP-UX, the default C compiler is not ANSI C compatible. If GNU |
||||
CC is not installed, it is recommended to use the following options in |
||||
order to use an ANSI C compiler: |
||||
|
||||
./configure CC="cc -Ae -D_XOPEN_SOURCE=500" |
||||
|
||||
and if that doesn't work, install pre-built binaries of GCC for HP-UX. |
||||
|
||||
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot |
||||
parse its `<wchar.h>' header file. The option `-nodtk' can be used as |
||||
a workaround. If GNU CC is not installed, it is therefore recommended |
||||
to try |
||||
|
||||
./configure CC="cc" |
||||
|
||||
and if that doesn't work, try |
||||
|
||||
./configure CC="cc -nodtk" |
||||
|
||||
On Solaris, don't put `/usr/ucb' early in your `PATH'. This |
||||
directory contains several dysfunctional programs; working variants of |
||||
these programs are available in `/usr/bin'. So, if you need `/usr/ucb' |
||||
in your `PATH', put it _after_ `/usr/bin'. |
||||
|
||||
On Haiku, software installed for all users goes in `/boot/common', |
||||
not `/usr/local'. It is recommended to use the following options: |
||||
|
||||
./configure --prefix=/boot/common |
||||
|
||||
Specifying the System Type |
||||
========================== |
||||
|
||||
There may be some features `configure' cannot figure out |
||||
automatically, but needs to determine by the type of machine the package |
||||
will run on. Usually, assuming the package is built to be run on the |
||||
_same_ architectures, `configure' can figure that out, but if it prints |
||||
a message saying it cannot guess the machine type, give it the |
||||
`--build=TYPE' option. TYPE can either be a short name for the system |
||||
type, such as `sun4', or a canonical name which has the form: |
||||
|
||||
CPU-COMPANY-SYSTEM |
||||
|
||||
where SYSTEM can have one of these forms: |
||||
|
||||
OS |
||||
KERNEL-OS |
||||
|
||||
See the file `config.sub' for the possible values of each field. If |
||||
`config.sub' isn't included in this package, then this package doesn't |
||||
need to know the machine type. |
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should |
||||
use the option `--target=TYPE' to select the type of system they will |
||||
produce code for. |
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a |
||||
platform different from the build platform, you should specify the |
||||
"host" platform (i.e., that on which the generated programs will |
||||
eventually be run) with `--host=TYPE'. |
||||
|
||||
Sharing Defaults |
||||
================ |
||||
|
||||
If you want to set default values for `configure' scripts to share, |
||||
you can create a site shell script called `config.site' that gives |
||||
default values for variables like `CC', `cache_file', and `prefix'. |
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then |
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the |
||||
`CONFIG_SITE' environment variable to the location of the site script. |
||||
A warning: not all `configure' scripts look for a site script. |
||||
|
||||
Defining Variables |
||||
================== |
||||
|
||||
Variables not defined in a site shell script can be set in the |
||||
environment passed to `configure'. However, some packages may run |
||||
configure again during the build, and the customized values of these |
||||
variables may be lost. In order to avoid this problem, you should set |
||||
them in the `configure' command line, using `VAR=value'. For example: |
||||
|
||||
./configure CC=/usr/local2/bin/gcc |
||||
|
||||
causes the specified `gcc' to be used as the C compiler (unless it is |
||||
overridden in the site shell script). |
||||
|
||||
Unfortunately, this technique does not work for `CONFIG_SHELL' due to |
||||
an Autoconf bug. Until the bug is fixed you can use this workaround: |
||||
|
||||
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash |
||||
|
||||
`configure' Invocation |
||||
====================== |
||||
|
||||
`configure' recognizes the following options to control how it |
||||
operates. |
||||
|
||||
`--help' |
||||
`-h' |
||||
Print a summary of all of the options to `configure', and exit. |
||||
|
||||
`--help=short' |
||||
`--help=recursive' |
||||
Print a summary of the options unique to this package's |
||||
`configure', and exit. The `short' variant lists options used |
||||
only in the top level, while the `recursive' variant lists options |
||||
also present in any nested packages. |
||||
|
||||
`--version' |
||||
`-V' |
||||
Print the version of Autoconf used to generate the `configure' |
||||
script, and exit. |
||||
|
||||
`--cache-file=FILE' |
||||
Enable the cache: use and save the results of the tests in FILE, |
||||
traditionally `config.cache'. FILE defaults to `/dev/null' to |
||||
disable caching. |
||||
|
||||
`--config-cache' |
||||
`-C' |
||||
Alias for `--cache-file=config.cache'. |
||||
|
||||
`--quiet' |
||||
`--silent' |
||||
`-q' |
||||
Do not print messages saying which checks are being made. To |
||||
suppress all normal output, redirect it to `/dev/null' (any error |
||||
messages will still be shown). |
||||
|
||||
`--srcdir=DIR' |
||||
Look for the package's source code in directory DIR. Usually |
||||
`configure' can determine that directory automatically. |
||||
|
||||
`--prefix=DIR' |
||||
Use DIR as the installation prefix. *note Installation Names:: |
||||
for more details, including other options available for fine-tuning |
||||
the installation locations. |
||||
|
||||
`--no-create' |
||||
`-n' |
||||
Run the configure checks, but stop before creating any output |
||||
files. |
||||
|
||||
`configure' also accepts some other, not widely useful, options. Run |
||||
`configure --help' for more details. |
