af8324
af8324
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
af8324
 Everyone is permitted to copy and distribute verbatim copies
af8324
 of this license document, but changing it is not allowed.
af8324
af8324
                            Preamble
af8324
af8324
  The GNU General Public License is a free, copyleft license for
af8324
software and other kinds of works.
af8324
af8324
  The licenses for most software and other practical works are designed
af8324
to take away your freedom to share and change the works.  By contrast,
af8324
the GNU General Public License is intended to guarantee your freedom to
af8324
share and change all versions of a program--to make sure it remains free
af8324
software for all its users.  We, the Free Software Foundation, use the
af8324
GNU General Public License for most of our software; it applies also to
af8324
any other work released this way by its authors.  You can apply it to
af8324
your programs, too.
af8324
af8324
  When we speak of free software, we are referring to freedom, not
af8324
price.  Our General Public Licenses are designed to make sure that you
af8324
have the freedom to distribute copies of free software (and charge for
af8324
them if you wish), that you receive source code or can get it if you
af8324
want it, that you can change the software or use pieces of it in new
af8324
free programs, and that you know you can do these things.
af8324
af8324
  To protect your rights, we need to prevent others from denying you
af8324
these rights or asking you to surrender the rights.  Therefore, you have
af8324
certain responsibilities if you distribute copies of the software, or if
af8324
you modify it: responsibilities to respect the freedom of others.
af8324
af8324
  For example, if you distribute copies of such a program, whether
af8324
gratis or for a fee, you must pass on to the recipients the same
af8324
freedoms that you received.  You must make sure that they, too, receive
af8324
or can get the source code.  And you must show them these terms so they
af8324
know their rights.
af8324
af8324
  Developers that use the GNU GPL protect your rights with two steps:
af8324
(1) assert copyright on the software, and (2) offer you this License
af8324
giving you legal permission to copy, distribute and/or modify it.
af8324
af8324
  For the developers' and authors' protection, the GPL clearly explains
af8324
that there is no warranty for this free software.  For both users' and
af8324
authors' sake, the GPL requires that modified versions be marked as
af8324
changed, so that their problems will not be attributed erroneously to
af8324
authors of previous versions.
af8324
af8324
  Some devices are designed to deny users access to install or run
af8324
modified versions of the software inside them, although the manufacturer
af8324
can do so.  This is fundamentally incompatible with the aim of
af8324
protecting users' freedom to change the software.  The systematic
af8324
pattern of such abuse occurs in the area of products for individuals to
af8324
use, which is precisely where it is most unacceptable.  Therefore, we
af8324
have designed this version of the GPL to prohibit the practice for those
af8324
products.  If such problems arise substantially in other domains, we
af8324
stand ready to extend this provision to those domains in future versions
af8324
of the GPL, as needed to protect the freedom of users.
af8324
af8324
  Finally, every program is threatened constantly by software patents.
af8324
States should not allow patents to restrict development and use of
af8324
software on general-purpose computers, but in those that do, we wish to
af8324
avoid the special danger that patents applied to a free program could
af8324
make it effectively proprietary.  To prevent this, the GPL assures that
af8324
patents cannot be used to render the program non-free.
af8324
af8324
  The precise terms and conditions for copying, distribution and
af8324
modification follow.
af8324
af8324
                       TERMS AND CONDITIONS
af8324
af8324
  0. Definitions.
af8324
af8324
  "This License" refers to version 3 of the GNU General Public License.
af8324
af8324
  "Copyright" also means copyright-like laws that apply to other kinds of
af8324
works, such as semiconductor masks.
af8324
af8324
  "The Program" refers to any copyrightable work licensed under this
af8324
License.  Each licensee is addressed as "you".  "Licensees" and
af8324
"recipients" may be individuals or organizations.
af8324
af8324
  To "modify" a work means to copy from or adapt all or part of the work
af8324
in a fashion requiring copyright permission, other than the making of an
af8324
exact copy.  The resulting work is called a "modified version" of the
af8324
earlier work or a work "based on" the earlier work.
af8324
af8324
  A "covered work" means either the unmodified Program or a work based
af8324
on the Program.
af8324
af8324
  To "propagate" a work means to do anything with it that, without
af8324
permission, would make you directly or secondarily liable for
af8324
infringement under applicable copyright law, except executing it on a
af8324
computer or modifying a private copy.  Propagation includes copying,
af8324
distribution (with or without modification), making available to the
af8324
public, and in some countries other activities as well.
af8324
af8324
  To "convey" a work means any kind of propagation that enables other
af8324
parties to make or receive copies.  Mere interaction with a user through
af8324
a computer network, with no transfer of a copy, is not conveying.
af8324
af8324
  An interactive user interface displays "Appropriate Legal Notices"
af8324
to the extent that it includes a convenient and prominently visible
af8324
feature that (1) displays an appropriate copyright notice, and (2)
af8324
tells the user that there is no warranty for the work (except to the
af8324
extent that warranties are provided), that licensees may convey the
af8324
work under this License, and how to view a copy of this License.  If
af8324
the interface presents a list of user commands or options, such as a
af8324
menu, a prominent item in the list meets this criterion.
af8324
af8324
  1. Source Code.
af8324
af8324
  The "source code" for a work means the preferred form of the work
af8324
for making modifications to it.  "Object code" means any non-source
af8324
form of a work.
af8324
af8324
  A "Standard Interface" means an interface that either is an official
af8324
standard defined by a recognized standards body, or, in the case of
af8324
interfaces specified for a particular programming language, one that
af8324
is widely used among developers working in that language.
af8324
af8324
  The "System Libraries" of an executable work include anything, other
af8324
than the work as a whole, that (a) is included in the normal form of
af8324
packaging a Major Component, but which is not part of that Major
af8324
Component, and (b) serves only to enable use of the work with that
af8324
Major Component, or to implement a Standard Interface for which an
af8324
implementation is available to the public in source code form.  A
af8324
"Major Component", in this context, means a major essential component
af8324
(kernel, window system, and so on) of the specific operating system
af8324
(if any) on which the executable work runs, or a compiler used to
af8324
produce the work, or an object code interpreter used to run it.
af8324
af8324
  The "Corresponding Source" for a work in object code form means all
af8324
the source code needed to generate, install, and (for an executable
af8324
work) run the object code and to modify the work, including scripts to
af8324
control those activities.  However, it does not include the work's
af8324
System Libraries, or general-purpose tools or generally available free
af8324
programs which are used unmodified in performing those activities but
af8324
which are not part of the work.  For example, Corresponding Source
af8324
includes interface definition files associated with source files for
af8324
the work, and the source code for shared libraries and dynamically
af8324
linked subprograms that the work is specifically designed to require,
af8324
such as by intimate data communication or control flow between those
af8324
subprograms and other parts of the work.
af8324
af8324
  The Corresponding Source need not include anything that users
af8324
can regenerate automatically from other parts of the Corresponding
af8324
Source.
af8324
af8324
  The Corresponding Source for a work in source code form is that
af8324
same work.
af8324
af8324
  2. Basic Permissions.
af8324
af8324
  All rights granted under this License are granted for the term of
af8324
copyright on the Program, and are irrevocable provided the stated
af8324
conditions are met.  This License explicitly affirms your unlimited
af8324
permission to run the unmodified Program.  The output from running a
af8324
covered work is covered by this License only if the output, given its
af8324
content, constitutes a covered work.  This License acknowledges your
af8324
rights of fair use or other equivalent, as provided by copyright law.
af8324
af8324
  You may make, run and propagate covered works that you do not
af8324
convey, without conditions so long as your license otherwise remains
af8324
in force.  You may convey covered works to others for the sole purpose
af8324
of having them make modifications exclusively for you, or provide you
af8324
with facilities for running those works, provided that you comply with
af8324
the terms of this License in conveying all material for which you do
af8324
not control copyright.  Those thus making or running the covered works
af8324
for you must do so exclusively on your behalf, under your direction
af8324
and control, on terms that prohibit them from making any copies of
af8324
your copyrighted material outside their relationship with you.
af8324
af8324
  Conveying under any other circumstances is permitted solely under
af8324
the conditions stated below.  Sublicensing is not allowed; section 10
af8324
makes it unnecessary.
af8324
af8324
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
af8324
af8324
  No covered work shall be deemed part of an effective technological
af8324
measure under any applicable law fulfilling obligations under article
af8324
11 of the WIPO copyright treaty adopted on 20 December 1996, or
af8324
similar laws prohibiting or restricting circumvention of such
af8324
measures.
af8324
af8324
  When you convey a covered work, you waive any legal power to forbid
af8324
circumvention of technological measures to the extent such circumvention
af8324
is effected by exercising rights under this License with respect to
af8324
the covered work, and you disclaim any intention to limit operation or
af8324
modification of the work as a means of enforcing, against the work's
af8324
users, your or third parties' legal rights to forbid circumvention of
af8324
technological measures.
af8324
af8324
  4. Conveying Verbatim Copies.
af8324
af8324
  You may convey verbatim copies of the Program's source code as you
af8324
receive it, in any medium, provided that you conspicuously and
af8324
appropriately publish on each copy an appropriate copyright notice;
af8324
keep intact all notices stating that this License and any
af8324
non-permissive terms added in accord with section 7 apply to the code;
af8324
keep intact all notices of the absence of any warranty; and give all
af8324
recipients a copy of this License along with the Program.
af8324
af8324
  You may charge any price or no price for each copy that you convey,
af8324
and you may offer support or warranty protection for a fee.
af8324
af8324
  5. Conveying Modified Source Versions.
af8324
af8324
  You may convey a work based on the Program, or the modifications to
af8324
produce it from the Program, in the form of source code under the
af8324
terms of section 4, provided that you also meet all of these conditions:
af8324
af8324
    a) The work must carry prominent notices stating that you modified
af8324
    it, and giving a relevant date.
af8324
af8324
    b) The work must carry prominent notices stating that it is
af8324
    released under this License and any conditions added under section
af8324
    7.  This requirement modifies the requirement in section 4 to
af8324
    "keep intact all notices".
af8324
af8324
    c) You must license the entire work, as a whole, under this
af8324
    License to anyone who comes into possession of a copy.  This
af8324
    License will therefore apply, along with any applicable section 7
af8324
    additional terms, to the whole of the work, and all its parts,
af8324
    regardless of how they are packaged.  This License gives no
af8324
    permission to license the work in any other way, but it does not
af8324
    invalidate such permission if you have separately received it.
af8324
af8324
    d) If the work has interactive user interfaces, each must display
af8324
    Appropriate Legal Notices; however, if the Program has interactive
af8324
    interfaces that do not display Appropriate Legal Notices, your
af8324
    work need not make them do so.
af8324
af8324
  A compilation of a covered work with other separate and independent
af8324
works, which are not by their nature extensions of the covered work,
af8324
and which are not combined with it such as to form a larger program,
af8324
in or on a volume of a storage or distribution medium, is called an
af8324
"aggregate" if the compilation and its resulting copyright are not
af8324
used to limit the access or legal rights of the compilation's users
af8324
beyond what the individual works permit.  Inclusion of a covered work
af8324
in an aggregate does not cause this License to apply to the other
af8324
parts of the aggregate.
af8324
af8324
  6. Conveying Non-Source Forms.
af8324
af8324
  You may convey a covered work in object code form under the terms
af8324
of sections 4 and 5, provided that you also convey the
af8324
machine-readable Corresponding Source under the terms of this License,
af8324
in one of these ways:
af8324
af8324
    a) Convey the object code in, or embodied in, a physical product
af8324
    (including a physical distribution medium), accompanied by the
af8324
    Corresponding Source fixed on a durable physical medium
af8324
    customarily used for software interchange.
af8324
af8324
    b) Convey the object code in, or embodied in, a physical product
af8324
    (including a physical distribution medium), accompanied by a
af8324
    written offer, valid for at least three years and valid for as
af8324
    long as you offer spare parts or customer support for that product
af8324
    model, to give anyone who possesses the object code either (1) a
af8324
    copy of the Corresponding Source for all the software in the
af8324
    product that is covered by this License, on a durable physical
af8324
    medium customarily used for software interchange, for a price no
af8324
    more than your reasonable cost of physically performing this
af8324
    conveying of source, or (2) access to copy the
af8324
    Corresponding Source from a network server at no charge.
af8324
af8324
    c) Convey individual copies of the object code with a copy of the
af8324
    written offer to provide the Corresponding Source.  This
af8324
    alternative is allowed only occasionally and noncommercially, and
af8324
    only if you received the object code with such an offer, in accord
af8324
    with subsection 6b.
af8324
af8324
    d) Convey the object code by offering access from a designated
af8324
    place (gratis or for a charge), and offer equivalent access to the
af8324
    Corresponding Source in the same way through the same place at no
af8324
    further charge.  You need not require recipients to copy the
af8324
    Corresponding Source along with the object code.  If the place to
af8324
    copy the object code is a network server, the Corresponding Source
af8324
    may be on a different server (operated by you or a third party)
af8324
    that supports equivalent copying facilities, provided you maintain
af8324
    clear directions next to the object code saying where to find the
af8324
    Corresponding Source.  Regardless of what server hosts the
af8324
    Corresponding Source, you remain obligated to ensure that it is
af8324
    available for as long as needed to satisfy these requirements.
af8324
af8324
    e) Convey the object code using peer-to-peer transmission, provided
af8324
    you inform other peers where the object code and Corresponding
af8324
    Source of the work are being offered to the general public at no
af8324
    charge under subsection 6d.
af8324
af8324
  A separable portion of the object code, whose source code is excluded
af8324
from the Corresponding Source as a System Library, need not be
af8324
included in conveying the object code work.
af8324
af8324
  A "User Product" is either (1) a "consumer product", which means any
af8324
tangible personal property which is normally used for personal, family,
af8324
or household purposes, or (2) anything designed or sold for incorporation
af8324
into a dwelling.  In determining whether a product is a consumer product,
af8324
doubtful cases shall be resolved in favor of coverage.  For a particular
af8324
product received by a particular user, "normally used" refers to a
af8324
typical or common use of that class of product, regardless of the status
af8324
of the particular user or of the way in which the particular user
af8324
actually uses, or expects or is expected to use, the product.  A product
af8324
is a consumer product regardless of whether the product has substantial
af8324
commercial, industrial or non-consumer uses, unless such uses represent
af8324
the only significant mode of use of the product.
af8324
af8324
  "Installation Information" for a User Product means any methods,
af8324
procedures, authorization keys, or other information required to install
af8324
and execute modified versions of a covered work in that User Product from
af8324
a modified version of its Corresponding Source.  The information must
af8324
suffice to ensure that the continued functioning of the modified object
af8324
code is in no case prevented or interfered with solely because
af8324
modification has been made.
af8324
af8324
  If you convey an object code work under this section in, or with, or
af8324
specifically for use in, a User Product, and the conveying occurs as
af8324
part of a transaction in which the right of possession and use of the
af8324
User Product is transferred to the recipient in perpetuity or for a
af8324
fixed term (regardless of how the transaction is characterized), the
af8324
Corresponding Source conveyed under this section must be accompanied
af8324
by the Installation Information.  But this requirement does not apply
af8324
if neither you nor any third party retains the ability to install
af8324
modified object code on the User Product (for example, the work has
af8324
been installed in ROM).
af8324
af8324
  The requirement to provide Installation Information does not include a
af8324
requirement to continue to provide support service, warranty, or updates
af8324
for a work that has been modified or installed by the recipient, or for
af8324
the User Product in which it has been modified or installed.  Access to a
af8324
network may be denied when the modification itself materially and
af8324
adversely affects the operation of the network or violates the rules and
af8324
protocols for communication across the network.
af8324
af8324
  Corresponding Source conveyed, and Installation Information provided,
af8324
in accord with this section must be in a format that is publicly
af8324
documented (and with an implementation available to the public in
af8324
source code form), and must require no special password or key for
af8324
unpacking, reading or copying.
af8324
af8324
  7. Additional Terms.
af8324
af8324
  "Additional permissions" are terms that supplement the terms of this
af8324
License by making exceptions from one or more of its conditions.
af8324
Additional permissions that are applicable to the entire Program shall
af8324
be treated as though they were included in this License, to the extent
af8324
that they are valid under applicable law.  If additional permissions
af8324
apply only to part of the Program, that part may be used separately
af8324
under those permissions, but the entire Program remains governed by
af8324
this License without regard to the additional permissions.
af8324
af8324
  When you convey a copy of a covered work, you may at your option
af8324
remove any additional permissions from that copy, or from any part of
af8324
it.  (Additional permissions may be written to require their own
af8324
removal in certain cases when you modify the work.)  You may place
af8324
additional permissions on material, added by you to a covered work,
af8324
for which you have or can give appropriate copyright permission.
af8324
af8324
  Notwithstanding any other provision of this License, for material you
af8324
add to a covered work, you may (if authorized by the copyright holders of
af8324
that material) supplement the terms of this License with terms:
af8324
af8324
    a) Disclaiming warranty or limiting liability differently from the
af8324
    terms of sections 15 and 16 of this License; or
af8324
af8324
    b) Requiring preservation of specified reasonable legal notices or
af8324
    author attributions in that material or in the Appropriate Legal
af8324
    Notices displayed by works containing it; or
af8324
af8324
    c) Prohibiting misrepresentation of the origin of that material, or
af8324
    requiring that modified versions of such material be marked in
af8324
    reasonable ways as different from the original version; or
af8324
af8324
    d) Limiting the use for publicity purposes of names of licensors or
af8324
    authors of the material; or
af8324
af8324
    e) Declining to grant rights under trademark law for use of some
af8324
    trade names, trademarks, or service marks; or
af8324
af8324
    f) Requiring indemnification of licensors and authors of that
af8324
    material by anyone who conveys the material (or modified versions of
af8324
    it) with contractual assumptions of liability to the recipient, for
af8324
    any liability that these contractual assumptions directly impose on
af8324
    those licensors and authors.
af8324
af8324
  All other non-permissive additional terms are considered "further
af8324
restrictions" within the meaning of section 10.  If the Program as you
af8324
received it, or any part of it, contains a notice stating that it is
af8324
governed by this License along with a term that is a further
af8324
restriction, you may remove that term.  If a license document contains
af8324
a further restriction but permits relicensing or conveying under this
af8324
License, you may add to a covered work material governed by the terms
af8324
of that license document, provided that the further restriction does
af8324
not survive such relicensing or conveying.
af8324
af8324
  If you add terms to a covered work in accord with this section, you
af8324
must place, in the relevant source files, a statement of the
af8324
additional terms that apply to those files, or a notice indicating
af8324
where to find the applicable terms.
af8324
af8324
  Additional terms, permissive or non-permissive, may be stated in the
af8324
form of a separately written license, or stated as exceptions;
af8324
the above requirements apply either way.
af8324
af8324
  8. Termination.
af8324
af8324
  You may not propagate or modify a covered work except as expressly
af8324
provided under this License.  Any attempt otherwise to propagate or
af8324
modify it is void, and will automatically terminate your rights under
af8324
this License (including any patent licenses granted under the third
af8324
paragraph of section 11).
af8324
af8324
  However, if you cease all violation of this License, then your
af8324
license from a particular copyright holder is reinstated (a)
af8324
provisionally, unless and until the copyright holder explicitly and
af8324
finally terminates your license, and (b) permanently, if the copyright
af8324
holder fails to notify you of the violation by some reasonable means
af8324
prior to 60 days after the cessation.
af8324
af8324
  Moreover, your license from a particular copyright holder is
af8324
reinstated permanently if the copyright holder notifies you of the
af8324
violation by some reasonable means, this is the first time you have
af8324
received notice of violation of this License (for any work) from that
af8324
copyright holder, and you cure the violation prior to 30 days after
af8324
your receipt of the notice.
af8324
af8324
  Termination of your rights under this section does not terminate the
af8324
licenses of parties who have received copies or rights from you under
af8324
this License.  If your rights have been terminated and not permanently
af8324
reinstated, you do not qualify to receive new licenses for the same
af8324
material under section 10.
af8324
af8324
  9. Acceptance Not Required for Having Copies.
af8324
af8324
  You are not required to accept this License in order to receive or
af8324
run a copy of the Program.  Ancillary propagation of a covered work
af8324
occurring solely as a consequence of using peer-to-peer transmission
af8324
to receive a copy likewise does not require acceptance.  However,
af8324
nothing other than this License grants you permission to propagate or
af8324
modify any covered work.  These actions infringe copyright if you do
af8324
not accept this License.  Therefore, by modifying or propagating a
af8324
covered work, you indicate your acceptance of this License to do so.
af8324
af8324
  10. Automatic Licensing of Downstream Recipients.
af8324
af8324
  Each time you convey a covered work, the recipient automatically
af8324
receives a license from the original licensors, to run, modify and
af8324
propagate that work, subject to this License.  You are not responsible
af8324
for enforcing compliance by third parties with this License.
af8324
af8324
  An "entity transaction" is a transaction transferring control of an
af8324
organization, or substantially all assets of one, or subdividing an
af8324
organization, or merging organizations.  If propagation of a covered
af8324
work results from an entity transaction, each party to that
af8324
transaction who receives a copy of the work also receives whatever
af8324
licenses to the work the party's predecessor in interest had or could
af8324
give under the previous paragraph, plus a right to possession of the
af8324
Corresponding Source of the work from the predecessor in interest, if
af8324
the predecessor has it or can get it with reasonable efforts.
af8324
af8324
  You may not impose any further restrictions on the exercise of the
af8324
rights granted or affirmed under this License.  For example, you may
af8324
not impose a license fee, royalty, or other charge for exercise of
af8324
rights granted under this License, and you may not initiate litigation
af8324
(including a cross-claim or counterclaim in a lawsuit) alleging that
af8324
any patent claim is infringed by making, using, selling, offering for
af8324
sale, or importing the Program or any portion of it.
af8324
af8324
  11. Patents.
af8324
af8324
  A "contributor" is a copyright holder who authorizes use under this
af8324
License of the Program or a work on which the Program is based.  The
af8324
work thus licensed is called the contributor's "contributor version".
af8324
af8324
  A contributor's "essential patent claims" are all patent claims
af8324
owned or controlled by the contributor, whether already acquired or
af8324
hereafter acquired, that would be infringed by some manner, permitted
af8324
by this License, of making, using, or selling its contributor version,
af8324
but do not include claims that would be infringed only as a
af8324
consequence of further modification of the contributor version.  For
af8324
purposes of this definition, "control" includes the right to grant
af8324
patent sublicenses in a manner consistent with the requirements of
af8324
this License.
af8324
af8324
  Each contributor grants you a non-exclusive, worldwide, royalty-free
af8324
patent license under the contributor's essential patent claims, to
af8324
make, use, sell, offer for sale, import and otherwise run, modify and
af8324
propagate the contents of its contributor version.
af8324
af8324
  In the following three paragraphs, a "patent license" is any express
af8324
agreement or commitment, however denominated, not to enforce a patent
af8324
(such as an express permission to practice a patent or covenant not to
af8324
sue for patent infringement).  To "grant" such a patent license to a
af8324
party means to make such an agreement or commitment not to enforce a
af8324
patent against the party.
af8324
af8324
  If you convey a covered work, knowingly relying on a patent license,
af8324
and the Corresponding Source of the work is not available for anyone
af8324
to copy, free of charge and under the terms of this License, through a
af8324
publicly available network server or other readily accessible means,
af8324
then you must either (1) cause the Corresponding Source to be so
af8324
available, or (2) arrange to deprive yourself of the benefit of the
af8324
patent license for this particular work, or (3) arrange, in a manner
af8324
consistent with the requirements of this License, to extend the patent
af8324
license to downstream recipients.  "Knowingly relying" means you have
af8324
actual knowledge that, but for the patent license, your conveying the
af8324
covered work in a country, or your recipient's use of the covered work
af8324
in a country, would infringe one or more identifiable patents in that
af8324
country that you have reason to believe are valid.
af8324
af8324
  If, pursuant to or in connection with a single transaction or
af8324
arrangement, you convey, or propagate by procuring conveyance of, a
af8324
covered work, and grant a patent license to some of the parties
af8324
receiving the covered work authorizing them to use, propagate, modify
af8324
or convey a specific copy of the covered work, then the patent license
af8324
you grant is automatically extended to all recipients of the covered
af8324
work and works based on it.
af8324
af8324
  A patent license is "discriminatory" if it does not include within
af8324
the scope of its coverage, prohibits the exercise of, or is
af8324
conditioned on the non-exercise of one or more of the rights that are
af8324
specifically granted under this License.  You may not convey a covered
af8324
work if you are a party to an arrangement with a third party that is
af8324
in the business of distributing software, under which you make payment
af8324
to the third party based on the extent of your activity of conveying
af8324
the work, and under which the third party grants, to any of the
af8324
parties who would receive the covered work from you, a discriminatory
af8324
patent license (a) in connection with copies of the covered work
af8324
conveyed by you (or copies made from those copies), or (b) primarily
af8324
for and in connection with specific products or compilations that
af8324
contain the covered work, unless you entered into that arrangement,
af8324
or that patent license was granted, prior to 28 March 2007.
af8324
af8324
  Nothing in this License shall be construed as excluding or limiting
af8324
any implied license or other defenses to infringement that may
af8324
otherwise be available to you under applicable patent law.
af8324
af8324
  12. No Surrender of Others' Freedom.
af8324
af8324
  If conditions are imposed on you (whether by court order, agreement or
af8324
otherwise) that contradict the conditions of this License, they do not
af8324
excuse you from the conditions of this License.  If you cannot convey a
af8324
covered work so as to satisfy simultaneously your obligations under this
af8324
License and any other pertinent obligations, then as a consequence you may
af8324
not convey it at all.  For example, if you agree to terms that obligate you
af8324
to collect a royalty for further conveying from those to whom you convey
af8324
the Program, the only way you could satisfy both those terms and this
af8324
License would be to refrain entirely from conveying the Program.
af8324
af8324
  13. Use with the GNU Affero General Public License.
af8324
af8324
  Notwithstanding any other provision of this License, you have
af8324
permission to link or combine any covered work with a work licensed
af8324
under version 3 of the GNU Affero General Public License into a single
af8324
combined work, and to convey the resulting work.  The terms of this
af8324
License will continue to apply to the part which is the covered work,
af8324
but the special requirements of the GNU Affero General Public License,
af8324
section 13, concerning interaction through a network will apply to the
af8324
combination as such.
af8324
af8324
  14. Revised Versions of this License.
af8324
af8324
  The Free Software Foundation may publish revised and/or new versions of
af8324
the GNU General Public License from time to time.  Such new versions will
af8324
be similar in spirit to the present version, but may differ in detail to
af8324
address new problems or concerns.
af8324
af8324
  Each version is given a distinguishing version number.  If the
af8324
Program specifies that a certain numbered version of the GNU General
af8324
Public License "or any later version" applies to it, you have the
af8324
option of following the terms and conditions either of that numbered
af8324
version or of any later version published by the Free Software
af8324
Foundation.  If the Program does not specify a version number of the
af8324
GNU General Public License, you may choose any version ever published
af8324
by the Free Software Foundation.
af8324
af8324
  If the Program specifies that a proxy can decide which future
af8324
versions of the GNU General Public License can be used, that proxy's
af8324
public statement of acceptance of a version permanently authorizes you
af8324
to choose that version for the Program.
af8324
af8324
  Later license versions may give you additional or different
af8324
permissions.  However, no additional obligations are imposed on any
af8324
author or copyright holder as a result of your choosing to follow a
af8324
later version.
af8324
af8324
  15. Disclaimer of Warranty.
af8324
af8324
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
af8324
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
af8324
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
af8324
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
af8324
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
af8324
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
af8324
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
af8324
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
af8324
af8324
  16. Limitation of Liability.
af8324
af8324
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
af8324
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
af8324
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
af8324
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
af8324
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
af8324
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
af8324
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
af8324
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
af8324
SUCH DAMAGES.
af8324
af8324
  17. Interpretation of Sections 15 and 16.
af8324
af8324
  If the disclaimer of warranty and limitation of liability provided
af8324
above cannot be given local legal effect according to their terms,
af8324
reviewing courts shall apply local law that most closely approximates
af8324
an absolute waiver of all civil liability in connection with the
af8324
Program, unless a warranty or assumption of liability accompanies a
af8324
copy of the Program in return for a fee.
af8324
af8324
                     END OF TERMS AND CONDITIONS
af8324
af8324
            How to Apply These Terms to Your New Programs
af8324
af8324
  If you develop a new program, and you want it to be of the greatest
af8324
possible use to the public, the best way to achieve this is to make it
af8324
free software which everyone can redistribute and change under these terms.
af8324
af8324
  To do so, attach the following notices to the program.  It is safest
af8324
to attach them to the start of each source file to most effectively
af8324
state the exclusion of warranty; and each file should have at least
af8324
the "copyright" line and a pointer to where the full notice is found.
af8324
af8324
    <one line to give the program's name and a brief idea of what it does.>
af8324
    Copyright (C) <year>  <name of author>
af8324
af8324
    This program is free software: you can redistribute it and/or modify
af8324
    it under the terms of the GNU General Public License as published by
af8324
    the Free Software Foundation, either version 3 of the License, or
af8324
    (at your option) any later version.
af8324
af8324
    This program is distributed in the hope that it will be useful,
af8324
    but WITHOUT ANY WARRANTY; without even the implied warranty of
af8324
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
af8324
    GNU General Public License for more details.
af8324
af8324
    You should have received a copy of the GNU General Public License
af8324
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
af8324
af8324
Also add information on how to contact you by electronic and paper mail.
af8324
af8324
  If the program does terminal interaction, make it output a short
af8324
notice like this when it starts in an interactive mode:
af8324
af8324
    <program>  Copyright (C) <year>  <name of author>
af8324
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
af8324
    This is free software, and you are welcome to redistribute it
af8324
    under certain conditions; type `show c' for details.
af8324
af8324
The hypothetical commands `show w' and `show c' should show the appropriate
af8324
parts of the General Public License.  Of course, your program's commands
af8324
might be different; for a GUI interface, you would use an "about box".
af8324
af8324
  You should also get your employer (if you work as a programmer) or school,
af8324
if any, to sign a "copyright disclaimer" for the program, if necessary.

af8324
af8324
  The GNU General Public License does not permit incorporating your program
af8324
into proprietary programs.  If your program is a subroutine library, you
af8324
may consider it more useful to permit linking proprietary applications with
af8324
the library.  If this is what you want to do, use the GNU Lesser General
af8324
Public License instead of this License.  But first, please read
