1 MOZILLA PUBLIC LICENSE - Version 1.0
- Definitions.
- ``Contributor'' means each entity that creates or contributes
to the creation of Modifications.
- ``Contributor Version'' means the combination of the Original
Code, prior Modifications used by a Contributor, and the
Modifications made by that particular Contributor.
- ``Covered Code'' means the Original Code or Modifications or
the combination of the Original Code and Modifications, in
each case including portions thereof.
- ``Electronic Distribution Mechanism'' means a mechanism
generally accepted in the software development community for
the electronic transfer of data.
- ``Executable'' means Covered Code in any form other than
Source Code.
- ``Initial Developer'' means the individual or entity
identified as the Initial Developer in the Source Code notice
required by Exhibit A.
- ``Larger Work'' means a work which combines Covered Code or
portions thereof with code not governed by the terms of this
License.
- ``License'' means this document.
- ``Modifications'' means any addition to or deletion from the
substance or structure of either the Original Code or any
previous Modifications. When Covered Code is released as a
series of files, a Modification is:
- Any addition to or deletion from the contents of a file
containing Original Code or previous Modifications.
- Any new file that contains any part of the Original Code
or previous Modifications.
- ``Original Code'' means Source Code of computer software code
which is described in the Source Code notice required by
Exhibit A as Original Code, and which, at the time of its
release under this License is not already Covered Code
governed by this License.
- ``Source Code'' means the preferred form of the Covered Code
for making modifications to it, including all modules it
contains, plus any associated interface definition files,
scripts used to control compilation and installation of an
Executable, or a list of source code differential comparisons
against either the Original Code or another well known,
available Covered Code of the Contributor's choice. The Source
Code can be in a compressed or archival form, provided the
appropriate decompression or de-archiving software is widely
available for no charge.
- ``You'' means an individual or a legal entity exercising
rights under, and complying with all of the terms of, this
License or a future version of this License issued under
Section 6(a). For legal entities, ``You'' includes any entity
which controls, is controlled by, or is under common control
with You. For purposes of this definition, ``control'' means
(a) the power, direct or indirect, to cause the direction or
management of such entity, whether by contract or otherwise,
or (b) ownership of fifty percent (50%) or more of the
outstanding shares or beneficial ownership of such entity.
- Source Code License.
- The Initial Developer Grant. The Initial Developer hereby
grants You a world-wide, royalty-free, non-exclusive license,
subject to third party intellectual property claims:
- to use, reproduce, modify, display, perform, sublicense
and distribute the Original Code (or portions thereof) with or
without Modifications, or as part of a Larger Work; and
- under patents now or hereafter owned or controlled by
Initial Developer, to make, have made, use and sell
(``Utilize'') the Original Code (or portions thereof), but
solely to the extent that any such patent is reasonably
necessary to enable You to Utilize the Original Code (or
portions thereof) and not to any greater extent that may be
necessary to Utilize further Modifications or combinations.
- Contributor Grant. Each Contributor hereby grants You a
world-wide, royalty-free, non-exclusive license, subject to
third party intellectual property claims:
- to use, reproduce, modify, display, perform, sublicense and
distribute the Modifications created by such Contributor (or
portions thereof) either on an unmodified basis, with other
Modifications, as Covered Code or as part of a Larger Work; and
- under patents now or hereafter owned or controlled by
Contributor, to Utilize the Contributor Version (or portions
thereof), but solely to the extent that any such patent is
reasonably necessary to enable You to Utilize the Contributor
Version (or portions thereof), and not to any greater extent that
may be necessary to Utilize further Modifications or
combinations.
- Distribution Obligations.
- Application of License.
The Modifications which You create or
to which You contribute are governed by the terms of this
License, including without limitation Section 2.2. The Source
Code version of Covered Code may be distributed only under the
terms of this License or a future version of this License
released under Section 6(a), and You must include a copy of
this License with every copy of the Source Code You
distribute. You may not offer or impose any terms on any
Source Code version that alters or restricts the applicable
version of this License or the recipients' rights
hereunder. However, You may include an additional document
offering the additional rights described in Section 3.5.
- Availability of Source Code.
Any Modification which You
create or to which You contribute must be made available in
Source Code form under the terms of this License either on the
same media as an Executable version or via an accepted
Electronic Distribution Mechanism to anyone to whom you made
an Executable version available; and if made available via
Electronic Distribution Mechanism, must remain available for
at least twelve (12) months after the date it initially became
available, or at least six (6) months after a subsequent
version of that particular Modification has been made
available to such recipients. You are responsible for ensuring
that the Source Code version remains available even if the
Electronic Distribution Mechanism is maintained by a third
party.
- Description of Modifications.
You must cause all Covered Code
to which you contribute to contain a file documenting the
changes You made to create that Covered Code and the date of
any change. You must include a prominent statement that the
Modification is derived, directly or indirectly, from Original
Code provided by the Initial Developer and including the name
of the Initial Developer in (a) the Source Code, and (b) in
any notice in an Executable version or related documentation
in which You describe the origin or ownership of the Covered
Code.
- Intellectual Property Matters
- Third Party Claims.
If You have knowledge that a party claims an intellectual
property right in particular functionality or code (or its
utilization under this License), you must include a text file
with the source code distribution titled ``LEGAL'' which
describes the claim and the party making the claim in sufficient
detail that a recipient will know whom to contact. If you obtain
such knowledge after You make Your Modification available as
described in Section 3(b), You shall promptly modify the LEGAL
file in all copies You make available thereafter and shall take
other steps (such as notifying appropriate mailing lists or
newsgroups) reasonably calculated to inform those who received
the Covered Code that new knowledge has been obtained.
- Contributor APIs.
If Your Modification is an application programming interface and
You own or control patents which are reasonably necessary to
implement that API, you must also include this information in the
LEGAL file.
- Required Notices.
You must duplicate the notice in Exhibit A
in each file of the Source Code, and this License in any
documentation for the Source Code, where You describe
recipients' rights relating to Covered Code. If You created
one or more Modification(s), You may add your name as a
Contributor to the notice described in Exhibit A. If it is not
possible to put such notice in a particular Source Code file
due to its structure, then you must include such notice in a
location (such as a relevant directory file) where a user
would be likely to look for such a notice. You may choose to
offer, and to charge a fee for, warranty, support, indemnity
or liability obligations to one or more recipients of Covered
Code. However, You may do so only on Your own behalf, and not
on behalf of the Initial Developer or any Contributor. You
must make it absolutely clear than any such warranty, support,
indemnity or liability obligation is offered by You alone, and
You hereby agree to indemnify the Initial Developer and every
Contributor for any liability incurred by the Initial
Developer or such Contributor as a result of warranty,
support, indemnity or liability terms You offer.
- Distribution of Executable Versions.
You may distribute
Covered Code in Executable form only if the requirements of
Section 3(a)-3(e) have been met for that Covered Code, and if
You include a notice stating that the Source Code version of
the Covered Code is available under the terms of this License,
including a description of how and where You have fulfilled
the obligations of Section 3(b). The notice must be
conspicuously included in any notice in an Executable version,
related documentation or collateral in which You describe
recipients' rights relating to the Covered Code. You may
distribute the Executable version of Covered Code under a
license of Your choice, which may contain terms different from
this License, provided that You are in compliance with the
terms of this License and that the license for the Executable
version does not attempt to limit or alter the recipient's
rights in the Source Code version from the rights set forth in
this License. If You distribute the Executable version under a
different license You must make it absolutely clear that any
terms which differ from this License are offered by You alone,
not by the Initial Developer or any Contributor. You hereby
agree to indemnify the Initial Developer and every Contributor
for any liability incurred by the Initial Developer or such
Contributor as a result of any such terms You offer.
- Larger Works.
You may create a Larger Work by combining
Covered Code with other code not governed by the terms of this
License and distribute the Larger Work as a single product. In
such a case, You must make sure the requirements of this
License are fulfilled for the Covered Code.
- Inability to Comply Due to Statute or Regulation.
If it is impossible for You to comply with any of the terms of
this License with respect to some or all of the Covered Code
due to statute or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and
(b) describe the limitations and the code they affect. Such
description must be included in the LEGAL file described in
Section 3.4 and must be included with all distributions of the
Source Code. Except to the extent prohibited by statute or
regulation, such description must be sufficiently detailed for
a recipient of ordinary skill to be able to understand it.
- Application of this License.
This License applies to code to which the Initial Developer
has attached the notice in Exhibit A, and to related Covered
Code.
- Versions of the License.
- New Versions.
Netscape Communications Corporation
(``Netscape'') may publish revised and/or new versions of the
License from time to time. Each version will be given a
distinguishing version number.
- Effect of New Versions.
Once Covered Code has been published
under a particular version of the License, You may always
continue to use it under the terms of that version. You may
also choose to use such Covered Code under the terms of any
subsequent version of the License published by Netscape. No
one other than Netscape has the right to modify the terms
applicable to Covered Code created under this License.
- Derivative Works.
If you create or use a modified version of
this License (which you may only do in order to apply it to
code which is not already Covered Code governed by this
License), you must (a) rename Your license so that the phrases
``Mozilla'', ``MOZILLAPL'', ``MOZPL'', ``Netscape'', ``NPL''
or any confusingly similar phrase do not appear anywhere in
your license and (b) otherwise make it clear that your version
of the license contains terms which differ from the Mozilla
Public License and Netscape Public License. (Filling in the
name of the Initial Developer, Original Code or Contributor in
the notice described in Exhibit A shall not of themselves be
deemed to be modifications of this License.)
- DISCLAIMER OF WARRANTY.
COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN ``AS IS''
BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE
COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A
PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO
THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH
YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR)
ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR
CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS
AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
- TERMINATION.
This License and the rights granted hereunder will terminate
automatically if You fail to comply with terms herein and fail
to cure such breach within 30 days of becoming aware of the
breach. All sublicenses to the Covered Code which are properly
granted shall survive any termination of this
License. Provisions which, by their nature, must remain in
effect beyond the termination of this License shall survive.
- LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
(INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE
INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR
OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE
LIABLE TO YOU OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL,
INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER
INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL
OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL
HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH
OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO
THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME
JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF
INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND
LIMITATION MAY NOT APPLY TO YOU.
- U.S. GOVERNMENT END USERS.
The Covered Code is a ``commercial item,'' as that term is
defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
``commercial computer software'' and ``commercial computer
software documentation,'' as such terms are used in 48
C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212
and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all
U.S. Government End Users acquire Covered Code with only those
rights set forth herein.
- MISCELLANEOUS.
This License represents the complete agreement concerning
subject matter hereof. If any provision of this License is
held to be unenforceable, such provision shall be reformed
only to the extent necessary to make it enforceable. This
License shall be governed by California law provisions (except
to the extent applicable law, if any, provides otherwise),
excluding its conflict-of-law provisions. With respect to
disputes in which at least one party is a citizen of, or an
entity chartered or registered to do business in, the United
States of America: (a) unless otherwise agreed in writing, all
disputes relating to this License (excepting any dispute
relating to intellectual property rights) shall be subject to
final and binding arbitration, with the losing party paying
all costs of arbitration; (b) any arbitration relating to this
Agreement shall be held in Santa Clara County, California,
under the auspices of JAMS/EndDispute; and (c) any litigation
relating to this Agreement shall be subject to the
jurisdiction of the Federal Courts of the Northern District of
California, with venue lying in Santa Clara County,
California, with the losing party responsible for costs,
including without limitation, court costs and reasonable
attorneys fees and expenses. The application of the United
Nations Convention on Contracts for the International Sale of
Goods is expressly excluded. Any law or regulation which
provides that the language of a contract shall be construed
against the drafter shall not apply to this License.
- RESPONSIBILITY FOR CLAIMS.
Except in cases where another Contributor has failed to comply
with Section 3.4, You are responsible for damages arising,
directly or indirectly, out of Your utilization of rights
under this License, based on the number of copies of Covered
Code you made available, the revenues you received from
utilizing such rights, and other relevant factors. You agree
to work with affected parties to distribute responsibility on
an equitable basis.

2 The License for the Qt Free Edition
Included below is version 1.0 of the license that will be offered
(along with all the new code features) for version 2.0 of the Qt Free
Edition. The license is called the Q Public License (or "QPL"), and
qualifies as an Open Source license. It is thus appropriate for people
wishing to write software under the Open Source model where all source
code to the software is made available to all users and can be freely
modified and redistributed.
The Qt 2.0 pre-release snapshots are licensed under the QPL 1.0
We would like to especially thank CEO Ransom Love and all the other
good people at Caldera Systems who have helped us in many ways during
the creation of the QPL. Their backing and feedback have been
invaluable during the process of making Qt Open Source.
We would also like to thank Joseph Carter, from the Debian project,
for his valuable input and Eric Raymond for his assistance.
The QPL has features that make it well suited to Qt:
- Modifications are distinct from the original, making it easier
to apply them to new Qt versions.
- Modifications can be incorporated into new Qt versions (at the
authors choice).
- Binaries can have the same name as the original - important
for dynamic libraries.
- Anyone can make bug-fixes - important for distributors of
systems.
- The Qt Free Edition can be used to run software written with
the Qt Professional Edition.
Free software development with the Qt Free Edition is additionally
protected by the KDE Free Qt Foundation, which of course remains
valid.
To develop software with the Qt Free Edition, simply meet the
requirements in the QPL. Your software can be licensed by any license
that permits the requirements in section 6.
THE Q PUBLIC LICENSE version 1.0
Copyright (C) 1999 Troll Tech AS, Norway.
Everyone is permitted to copy and
distribute this license document.
The intent of this license is to establish freedom to share and change the
software regulated by this license under the open source model.
This license applies to any software containing a notice placed by the
copyright holder saying that it may be distributed under the terms of the Q
Public License version 1.0. Such software is herein referred to as the
Software. This license covers modification and distribution of the
Software, use of third-party application programs based on the Software,
and development of free software which uses the Software.
Granted Rights
- You are granted the non-exclusive rights set forth in this
license provided you agree to and comply with any and all
conditions in this license. Whole or partial distribution of
the Software, or software items that link with the Software,
in any form signifies acceptance of this license.
- You may copy and distribute the Software in unmodified form
provided that the entire package, including - but not
restricted to - copyright, trademark notices and disclaimers,
as released by the initial developer of the Software, is
distributed.
- You may make modifications to the Software and distribute your
modifications, in a form that is separate from the Software,
such as patches. The following restrictions apply to
modifications:
- Modifications must not alter or remove any copyright
notices in the Software.
- When modifications to the Software are released under
this license, a non-exclusive royalty-free right is granted to
the initial developer of the Software to distribute your
modification in future versions of the Software provided such
versions remain available under these terms in addition to any
other license(s) of the initial developer.
- You may distribute machine-executable forms of the Software or
machine-executable forms of modified versions of the Software,
provided that you meet these restrictions:
- You must include this license document in the
distribution.
- You must ensure that all recipients of the
machine-executable forms are also able to receive the complete
machine-readable source code to the distributed Software,
including all modifications, without any charge beyond the
costs of data transfer, and place prominent notices in the
distribution explaining this.
- You must ensure that all modifications included in the
machine-executable forms are available under the terms of this
license.
- You may use the original or modified versions of the Software
to compile, link and run application programs legally
developed by you or by others.
- You may develop application programs, reusable components and
other software items that link with the original or modified
versions of the Software. These items, when distributed, are
subject to the following requirements:
- You must ensure that all recipients of
machine-executable forms of these items are also able to
receive and use the complete machine-readable source code to
the items without any charge beyond the costs of data
transfer.
- You must explicitly license all recipients of your items
to use and re-distribute original and modified versions of the
items in both machine-executable and source code forms. The
recipients must be able to do so without any charges
whatsoever, and they must be able to re-distribute to anyone
they choose.
- If the items are not available to the general public,
and the initial developer of the Software requests a copy of
the items, then you must supply one.
Limitations of Liability
In no event shall the initial developers or copyright holders be
liable for any damages whatsoever, including - but not restricted to -
lost revenue or profits or other direct, indirect, special, incidental
or consequential damages, even if they have been advised of the
possibility of such damages, except to the extent invariable law, if
any, provides otherwise.
No Warranty
The Software and this license document are provided AS IS with NO
WARRANTY OF ANY KIND, INCLUDING THE WARRANTY OF DESIGN,
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
Choice of Law
This license is governed by the Laws of Norway. Disputes shall be
settled by Oslo City Court.
This is not a legal document. For the exact interpretation of the
license you must read it and understand it. This page is simply meant
to explain the license in an easy to understand and informal way.
THE ANNOTATED Q PUBLIC LICENSE VERSION 1.0
AS APPLIED TO The Qt Free Edition VERSION 2.0
Copyright (C) 1999 Troll Tech AS, Norway.
Everyone is permitted to copy and
distribute this license document.
The intent of this license is to establish freedom to share and change
the software regulated by this license under the open source model.
This license applies to any software containing a notice placed by the
copyright holder saying that it may be distributed under the terms of
the Q Public License version 1.0. Such software is herein referred to
as the Software. This license covers modification and distribution of
the Software, use of third-party application programs based on the
Software, and development of free software which uses the Software.
Granted Rights
- You are granted the non-exclusive rights set forth in this
license provided you agree to and comply with any and all
conditions in this license. Whole or partial distribution of
the Software, or software items that link with the Software,
in any form signifies acceptance of this license.
This is to ensure that everyone follows the rules. If you do
not accept this license you are not given the right to
distribute the software, to make modifications to it nor
develop anything with it.
- You may copy and distribute the Software in unmodified form
provided that the entire package, including - but not
restricted to - copyright, trademark notices and disclaimers,
as released by the initial developer of the Software, is
distributed.
Distribute the software, i.e. Qt, to anyone you like, as long
as you include everything in the original distribution. In
order to preserve the integrity of the unmodified version,
modifications are restricted to being separated in some way
from the original Qt source code.
- You may make modifications to the Software and distribute your
modifications, in a form that is separate from the Software,
such as patches. The following restrictions apply to
modifications:
You can make and distribute changes, the preferred form being
patches.
You cannot just change the code and redistribute it, as this
would not be separate - people would not know what part of the
software is Qt and what part is the changes you made.
The easiest way to deal with this is to use a version
management system such as CVS - you will find that it is in
fact much easier to distribute patches than to try to deal
with entire files. With patches, you can easily incorporate
changes made by others into your copy of Qt.
You may also distribute a modified binary version if you
include the patch (see 4).
Patches should include an accurate description of the
modification, the date of the modification, and the author of
the modification.
A typical patch is shown below.
Copyright (C) 1998 Harald Acker
This patch may be distributed under the terms of the Q
Public License, version 1.0 or later.
This patch is for Qt 2.42. It fixes the bug where Foo
objects move right when they should move left.

Any technique is acceptable for keeping changes separate -
generally, you would have to mark changes very clearly for
them to be separate. We don't want to hard-code the idea that
the form must be patches.
- Modifications must not alter or remove any copyright
notices in the Software.
This doesn't really need to be stated, since to do so would be
fraudulent.
- When modifications to the Software are released under
this license, a non-exclusive royalty-free right is granted to
the initial developer of the Software to distribute your
modification in future versions of the Software provided such
versions remain available under these terms in addition to any
other license(s) of the initial developer.
You may license your patch any way you see fit, but note that
when distributed in a binary form of Qt, it must be licensed
under the QPL - this is explained in section 4.
This clause makes it possible for Troll Tech to include
patches in new versions of Qt. It also means that the same
patches can be included in the Qt Professional Edition, but
Troll Tech are in turn required to ensure that those changes
are in both versions.
- You may distribute machine-executable forms of the Software or
machine-executable forms of modified versions of the Software,
provided that you meet these restrictions:
You may distribute binaries.
- You must include this license document in the
distribution.
You must tell the recipients about their rights.
- You must ensure that all recipients of the
machine-executable forms are also able to receive the complete
machine-readable source code to the distributed Software,
including all modifications, without any charge beyond the
costs of data transfer, and place prominent notices in the
distribution explaining this.
The easiest way to achieve this is to have the source code
accompany the binary version. For FTP distribution, it should
be just as accessible. For CD-ROM distribution, it should be
on an accompanying CD. The basic rule here is "binary follows
source".
- You must ensure that all modifications included in the
machine-executable forms are available under the terms of this
license.
Most patches contain quoted Qt code, plus work of your
own. You may license your patch any way you see fit, but when
distributed in a binary form of Qt, it must be licensed under
the QPL. Be careful if taking code from other sources to
include in Qt - that other software may not allow such
copying.
Why? Without this restriction, nothing would prevent modified
versions of Qt, licensed under non-free licensing.
- You may use the original or modified versions of the Software
to compile, link and run application programs legally
developed by you or by others.
If you have a program written for the software, go ahead and
use it. This allows you to use software created under either
the Qt Free Edition license or the Qt Professional Edition
license with the one library version.
- You may develop application programs, reusable components and
other software items that link with the original or modified
versions of the Software. These items, when distributed, are
subject to the following requirements:
This is a license designed for libraries, therefore we must
also talk about application programs or other libraries
(components) that are linked with the software, as these
include portions of Qt when in binary form. Of course, given
the term "link", there is no differentiation between static
and dynamic linking.
In essence this clause says that you may develop programs that
link with Qt provided that you develop Open Source software.
- You must ensure that all recipients of
machine-executable forms of these items are also able to
receive and use the complete machine-readable source code to
the items without any charge beyond the costs of data
transfer.
Like 4b., "source follows binary". You are free to charge for
binaries, however you must also supply the source code. Note
that "all recipients" includes recipients that you do not
directly transfer copies to. The easiest way to achieve this
is to allow (or insist) that all recipients can further
distribute the source.
- You must explicitly license all recipients of your items
to use and re-distribute original and modified versions of the
items in both machine-executable and source code forms. The
recipients must be able to do so without any charges
whatsoever, and they must be able to re-distribute to anyone
they choose.
This ensures that all recipients have the same rights, no
matter how or from whom they received the software. The
easiest way to provide this explicit license is to allow
recipients to grant the same license to others.
If the recipients of your software wishes to do so they may
re-distribute your software without anyone having to pay money
either to them or to you.
- If the items are not available to the general public,
and the initial developer of the Software requests a copy of
the items, then you must supply one.
This is to avoid problems with companies that try to hide the
source. If we get to know about it we want to be able to get
hold of the code even if we are not users. In this way, if
somebody tries to cheat and we get to know we can release the
code to the public.
Limitations of Liability
In no event shall the initial developers or copyright holders be
liable for any damages whatsoever, including - but not restricted to -
lost revenue or profits or other direct, indirect, special, incidental
or consequential damages, even if they have been advised of the
possibility of such damages, except to the extent invariable law, if
any, provides otherwise.
No Warranty
The Software and this license document are provided AS IS with NO
WARRANTY OF ANY KIND, INCLUDING THE WARRANTY OF DESIGN,
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
Choice of Law
This license is governed by the Laws of Norway. Disputes shall be
settled by Oslo City Court.
This LGPL is meant to be included from other files.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, 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
this service 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 make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
``work based on the library'' and a ``work that uses the library''. The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
- This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called ``this License''). Each licensee is
addressed as ``you''.
A ``library'' means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The ``Library'', below, refers to any such software library or work
which has been distributed under these terms. A ``work based on the
Library'' means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term ``modification''.)
``Source code'' for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
- You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
- You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
- The modified work must itself be a software library.
- You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
- You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
- If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, 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 every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
- You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
- You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
- A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a ``work that uses the Library''. Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a ``work that uses the Library'' with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a ``work that uses the
library''. The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a ``work that uses the Library'' uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
- As an exception to the Sections above, you may also compile or
link a ``work that uses the Library'' with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
- Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable ``work that
uses the Library'', as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
- Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
- If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
- Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the ``work that uses the
Library'' must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
- You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
- Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
- Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
- You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
- You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
- Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
- If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
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
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
- If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
- The Free Software Foundation may publish revised and/or new
versions of the Library 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 Library
specifies a version number of this License which applies to it and
``any later version'', you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
- If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
- BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY ``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
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY 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
LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey 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 library's name and an idea of what it does.
Copyright (C) year name of author
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library 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
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the
Free Software Foundation, Inc., 675 Mass Ave, Cambridge,
MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a ``copyright disclaimer'' for the library, if
necessary. Here is a sample; alter the names:

5 GNU GENERAL PUBLIC LICENSE
GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass
Ave, Cambridge, MA 02139, USA. Everyone 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 away your
freedom to share and change it. By contrast, the GNU General 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 authors commit
to using it. (Some other Free Software Foundation software is
covered by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the
rights. These restrictions translate to certain responsibilities
for you if you distribute copies of the software, or if you modify
it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights
that you have. 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.
We protect your rights with two steps: (1) copyright the software,
and (2) offer you this license which gives you legal permission to
copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make
certain that everyone understands that there is no warranty for
this free software. If the software is modified by someone else and
passed on, we want its recipients to know that what they have is
not the original, so that any problems introduced by others will
not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making
the program proprietary. To prevent this, we have made it clear
that any patent must be licensed for everyone's free use or not
licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work
based on the Program" means either the Program or any derivative
work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications
and/or translated into another language. (Hereinafter, translation
is included without limitation in the term "modification".) Each
licensee is addressed as "you".
Activities other than copying, distribution and modification are
not covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the
Program is covered only if its contents constitute a work based on
the Program (independent of having been made by running the
Program). Whether that is true depends on what the Program does.
1. You may copy and distribute 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 and disclaimer of warranty; 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.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange
for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work 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) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users 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 interactive but does
not normally print such an announcement, your work based on the
Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not apply
to those sections when you distribute them as separate works. But
when you distribute the same sections as part of a whole which is a
work based on the Program, 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 every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather, the
intent is to exercise the right to control the distribution of
derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the
Program with the Program (or with a work based on the Program) on a
volume of a storage or distribution medium does not bring the other
work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you also do one of the
following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed 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
years, to give any third party, for a charge no more than your cost
of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed 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 received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received 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 form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus
any associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as
a special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of
the operating system on which the executable runs, unless that
component itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
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, parties who have received copies, or rights, from
you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or
modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject
to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted
herein. You are not responsible for enforcing compliance by third
parties to this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent
issues), 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 distribute so as to satisfy simultaneously
your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the
Program at all. For example, if a patent license would not permit
royalty-free redistribution of the Program by all those who receive
copies directly or indirectly through you, then the only way you
could satisfy both it and this License would be to refrain entirely
from distribution of the Program.
If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section is
intended to apply and the section as a whole is intended to apply
in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is
willing to distribute software through any other system and a
licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Program under this
License may add an explicit geographical distribution limitation
excluding those countries, so that distribution is permitted only
in or among countries not thus excluded. In such case, this License
incorporates the limitation as if written in the body of this
License.
9. The Free Software Foundation may publish revised and/or new
versions of the 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 a version number of this License which applies to
it and "any later version", you have the option of following the
terms and conditions either of that version or of any later version
published by the Free Software Foundation. If the Program does not
specify a version number of this License, you may choose any
version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted by
the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our decision
will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE 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.
