 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
01b97e
 Everyone is permitted to copy and distribute verbatim copies
01b97e
 of this license document, but changing it is not allowed.
01b97e
01b97e
                            Preamble
01b97e
01b97e
  The GNU General Public License is a free, copyleft license for
01b97e
software and other kinds of works.
01b97e
01b97e
  The licenses for most software and other practical works are designed
01b97e
to take away your freedom to share and change the works.  By contrast,
01b97e
the GNU General Public License is intended to guarantee your freedom to
01b97e
share and change all versions of a program--to make sure it remains free
01b97e
software for all its users.  We, the Free Software Foundation, use the
01b97e
GNU General Public License for most of our software; it applies also to
01b97e
any other work released this way by its authors.  You can apply it to
01b97e
your programs, too.
01b97e
01b97e
  When we speak of free software, we are referring to freedom, not
01b97e
price.  Our General Public Licenses are designed to make sure that you
01b97e
have the freedom to distribute copies of free software (and charge for
01b97e
them if you wish), that you receive source code or can get it if you
01b97e
want it, that you can change the software or use pieces of it in new
01b97e
free programs, and that you know you can do these things.
01b97e
01b97e
  To protect your rights, we need to prevent others from denying you
01b97e
these rights or asking you to surrender the rights.  Therefore, you have
01b97e
certain responsibilities if you distribute copies of the software, or if
01b97e
you modify it: responsibilities to respect the freedom of others.
01b97e
01b97e
  For example, if you distribute copies of such a program, whether
01b97e
gratis or for a fee, you must pass on to the recipients the same
01b97e
freedoms that you received.  You must make sure that they, too, receive
01b97e
or can get the source code.  And you must show them these terms so they
01b97e
know their rights.
01b97e
01b97e
  Developers that use the GNU GPL protect your rights with two steps:
01b97e
(1) assert copyright on the software, and (2) offer you this License
01b97e
giving you legal permission to copy, distribute and/or modify it.
01b97e
01b97e
  For the developers' and authors' protection, the GPL clearly explains
01b97e
that there is no warranty for this free software.  For both users' and
01b97e
authors' sake, the GPL requires that modified versions be marked as
01b97e
changed, so that their problems will not be attributed erroneously to
01b97e
authors of previous versions.
01b97e
01b97e
  Some devices are designed to deny users access to install or run
01b97e
modified versions of the software inside them, although the manufacturer
01b97e
can do so.  This is fundamentally incompatible with the aim of
01b97e
protecting users' freedom to change the software.  The systematic
01b97e
pattern of such abuse occurs in the area of products for individuals to
01b97e
use, which is precisely where it is most unacceptable.  Therefore, we
01b97e
have designed this version of the GPL to prohibit the practice for those
01b97e
products.  If such problems arise substantially in other domains, we
01b97e
stand ready to extend this provision to those domains in future versions
01b97e
of the GPL, as needed to protect the freedom of users.
01b97e
01b97e
  Finally, every program is threatened constantly by software patents.
01b97e
States should not allow patents to restrict development and use of
01b97e
software on general-purpose computers, but in those that do, we wish to
01b97e
avoid the special danger that patents applied to a free program could
01b97e
make it effectively proprietary.  To prevent this, the GPL assures that
01b97e
patents cannot be used to render the program non-free.
01b97e
01b97e
  The precise terms and conditions for copying, distribution and
01b97e
modification follow.
01b97e
01b97e
                       TERMS AND CONDITIONS
01b97e
01b97e
  0. Definitions.
01b97e
01b97e
  "This License" refers to version 3 of the GNU General Public License.
01b97e
01b97e
  "Copyright" also means copyright-like laws that apply to other kinds of
01b97e
works, such as semiconductor masks.
01b97e
01b97e
  "The Program" refers to any copyrightable work licensed under this
01b97e
License.  Each licensee is addressed as "you".  "Licensees" and
01b97e
"recipients" may be individuals or organizations.
01b97e
01b97e
  To "modify" a work means to copy from or adapt all or part of the work
01b97e
in a fashion requiring copyright permission, other than the making of an
01b97e
exact copy.  The resulting work is called a "modified version" of the
01b97e
earlier work or a work "based on" the earlier work.
01b97e
01b97e
  A "covered work" means either the unmodified Program or a work based
01b97e
on the Program.
01b97e
01b97e
  To "propagate" a work means to do anything with it that, without
01b97e
permission, would make you directly or secondarily liable for
01b97e
infringement under applicable copyright law, except executing it on a
01b97e
computer or modifying a private copy.  Propagation includes copying,
01b97e
distribution (with or without modification), making available to the
01b97e
public, and in some countries other activities as well.
01b97e
01b97e
  To "convey" a work means any kind of propagation that enables other
01b97e
parties to make or receive copies.  Mere interaction with a user through
01b97e
a computer network, with no transfer of a copy, is not conveying.
01b97e
01b97e
  An interactive user interface displays "Appropriate Legal Notices"
01b97e
to the extent that it includes a convenient and prominently visible
01b97e
feature that (1) displays an appropriate copyright notice, and (2)
01b97e
tells the user that there is no warranty for the work (except to the
01b97e
extent that warranties are provided), that licensees may convey the
01b97e
work under this License, and how to view a copy of this License.  If
01b97e
the interface presents a list of user commands or options, such as a
01b97e
menu, a prominent item in the list meets this criterion.
01b97e
01b97e
  1. Source Code.
01b97e
01b97e
  The "source code" for a work means the preferred form of the work
01b97e
for making modifications to it.  "Object code" means any non-source
01b97e
form of a work.
01b97e
01b97e
  A "Standard Interface" means an interface that either is an official
01b97e
standard defined by a recognized standards body, or, in the case of
01b97e
interfaces specified for a particular programming language, one that
01b97e
is widely used among developers working in that language.
01b97e
01b97e
  The "System Libraries" of an executable work include anything, other
01b97e
than the work as a whole, that (a) is included in the normal form of
01b97e
packaging a Major Component, but which is not part of that Major
01b97e
Component, and (b) serves only to enable use of the work with that
01b97e
Major Component, or to implement a Standard Interface for which an
01b97e
implementation is available to the public in source code form.  A
01b97e
"Major Component", in this context, means a major essential component
01b97e
(kernel, window system, and so on) of the specific operating system
01b97e
(if any) on which the executable work runs, or a compiler used to
01b97e
produce the work, or an object code interpreter used to run it.
01b97e
01b97e
  The "Corresponding Source" for a work in object code form means all
01b97e
the source code needed to generate, install, and (for an executable
01b97e
work) run the object code and to modify the work, including scripts to
01b97e
control those activities.  However, it does not include the work's
01b97e
System Libraries, or general-purpose tools or generally available free
01b97e
programs which are used unmodified in performing those activities but
01b97e
which are not part of the work.  For example, Corresponding Source
01b97e
includes interface definition files associated with source files for
01b97e
the work, and the source code for shared libraries and dynamically
01b97e
linked subprograms that the work is specifically designed to require,
01b97e
such as by intimate data communication or control flow between those
01b97e
subprograms and other parts of the work.
01b97e
01b97e
  The Corresponding Source need not include anything that users
01b97e
can regenerate automatically from other parts of the Corresponding
01b97e
Source.
01b97e
01b97e
  The Corresponding Source for a work in source code form is that
01b97e
same work.
01b97e
01b97e
  2. Basic Permissions.
01b97e
01b97e
  All rights granted under this License are granted for the term of
01b97e
copyright on the Program, and are irrevocable provided the stated
01b97e
conditions are met.  This License explicitly affirms your unlimited
01b97e
permission to run the unmodified Program.  The output from running a
01b97e
covered work is covered by this License only if the output, given its
01b97e
content, constitutes a covered work.  This License acknowledges your
01b97e
rights of fair use or other equivalent, as provided by copyright law.
01b97e
01b97e
  You may make, run and propagate covered works that you do not
01b97e
convey, without conditions so long as your license otherwise remains
01b97e
in force.  You may convey covered works to others for the sole purpose
01b97e
of having them make modifications exclusively for you, or provide you
01b97e
with facilities for running those works, provided that you comply with
01b97e
the terms of this License in conveying all material for which you do
01b97e
not control copyright.  Those thus making or running the covered works
01b97e
for you must do so exclusively on your behalf, under your direction
01b97e
and control, on terms that prohibit them from making any copies of
01b97e
your copyrighted material outside their relationship with you.
01b97e
01b97e
  Conveying under any other circumstances is permitted solely under
01b97e
the conditions stated below.  Sublicensing is not allowed; section 10
01b97e
makes it unnecessary.
01b97e
01b97e
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
01b97e
01b97e
  No covered work shall be deemed part of an effective technological
01b97e
measure under any applicable law fulfilling obligations under article
01b97e
11 of the WIPO copyright treaty adopted on 20 December 1996, or
01b97e
similar laws prohibiting or restricting circumvention of such
01b97e
measures.
01b97e
01b97e
  When you convey a covered work, you waive any legal power to forbid
01b97e
circumvention of technological measures to the extent such circumvention
01b97e
is effected by exercising rights under this License with respect to
01b97e
the covered work, and you disclaim any intention to limit operation or
01b97e
modification of the work as a means of enforcing, against the work's
01b97e
users, your or third parties' legal rights to forbid circumvention of
01b97e
technological measures.
01b97e
01b97e
  4. Conveying Verbatim Copies.
01b97e
01b97e
  You may convey verbatim copies of the Program's source code as you
01b97e
receive it, in any medium, provided that you conspicuously and
01b97e
appropriately publish on each copy an appropriate copyright notice;
01b97e
keep intact all notices stating that this License and any
01b97e
non-permissive terms added in accord with section 7 apply to the code;
01b97e
keep intact all notices of the absence of any warranty; and give all
01b97e
recipients a copy of this License along with the Program.
01b97e
01b97e
  You may charge any price or no price for each copy that you convey,
01b97e
and you may offer support or warranty protection for a fee.
01b97e
01b97e
  5. Conveying Modified Source Versions.
01b97e
01b97e
  You may convey a work based on the Program, or the modifications to
01b97e
produce it from the Program, in the form of source code under the
01b97e
terms of section 4, provided that you also meet all of these conditions:
01b97e
01b97e
    a) The work must carry prominent notices stating that you modified
01b97e
    it, and giving a relevant date.
01b97e
01b97e
    b) The work must carry prominent notices stating that it is
01b97e
    released under this License and any conditions added under section
01b97e
    7.  This requirement modifies the requirement in section 4 to
01b97e
    "keep intact all notices".
01b97e
01b97e
    c) You must license the entire work, as a whole, under this
01b97e
    License to anyone who comes into possession of a copy.  This
01b97e
    License will therefore apply, along with any applicable section 7
01b97e
    additional terms, to the whole of the work, and all its parts,
01b97e
    regardless of how they are packaged.  This License gives no
01b97e
    permission to license the work in any other way, but it does not
01b97e
    invalidate such permission if you have separately received it.
01b97e
01b97e
    d) If the work has interactive user interfaces, each must display
01b97e
    Appropriate Legal Notices; however, if the Program has interactive
01b97e
    interfaces that do not display Appropriate Legal Notices, your
01b97e
    work need not make them do so.
01b97e
01b97e
  A compilation of a covered work with other separate and independent
01b97e
works, which are not by their nature extensions of the covered work,
01b97e
and which are not combined with it such as to form a larger program,
01b97e
in or on a volume of a storage or distribution medium, is called an
01b97e
"aggregate" if the compilation and its resulting copyright are not
01b97e
used to limit the access or legal rights of the compilation's users
01b97e
beyond what the individual works permit.  Inclusion of a covered work
01b97e
in an aggregate does not cause this License to apply to the other
01b97e
parts of the aggregate.
01b97e
01b97e
  6. Conveying Non-Source Forms.
01b97e
01b97e
  You may convey a covered work in object code form under the terms
01b97e
of sections 4 and 5, provided that you also convey the
01b97e
machine-readable Corresponding Source under the terms of this License,
01b97e
in one of these ways:
01b97e
01b97e
    a) Convey the object code in, or embodied in, a physical product
01b97e
    (including a physical distribution medium), accompanied by the
01b97e
    Corresponding Source fixed on a durable physical medium
01b97e
    customarily used for software interchange.
01b97e
01b97e
    b) Convey the object code in, or embodied in, a physical product
01b97e
    (including a physical distribution medium), accompanied by a
01b97e
    written offer, valid for at least three years and valid for as
01b97e
    long as you offer spare parts or customer support for that product
01b97e
    model, to give anyone who possesses the object code either (1) a
01b97e
    copy of the Corresponding Source for all the software in the
01b97e
    product that is covered by this License, on a durable physical
01b97e
    medium customarily used for software interchange, for a price no
01b97e
    more than your reasonable cost of physically performing this
01b97e
    conveying of source, or (2) access to copy the
01b97e
    Corresponding Source from a network server at no charge.
01b97e
01b97e
    c) Convey individual copies of the object code with a copy of the
01b97e
    written offer to provide the Corresponding Source.  This
01b97e
    alternative is allowed only occasionally and noncommercially, and
01b97e
    only if you received the object code with such an offer, in accord
01b97e
    with subsection 6b.
01b97e
01b97e
    d) Convey the object code by offering access from a designated
01b97e
    place (gratis or for a charge), and offer equivalent access to the
01b97e
    Corresponding Source in the same way through the same place at no
01b97e
    further charge.  You need not require recipients to copy the
01b97e
    Corresponding Source along with the object code.  If the place to
01b97e
    copy the object code is a network server, the Corresponding Source
01b97e
    may be on a different server (operated by you or a third party)
01b97e
    that supports equivalent copying facilities, provided you maintain
01b97e
    clear directions next to the object code saying where to find the
01b97e
    Corresponding Source.  Regardless of what server hosts the
01b97e
    Corresponding Source, you remain obligated to ensure that it is
01b97e
    available for as long as needed to satisfy these requirements.
01b97e
01b97e
    e) Convey the object code using peer-to-peer transmission, provided
01b97e
    you inform other peers where the object code and Corresponding
01b97e
    Source of the work are being offered to the general public at no
01b97e
    charge under subsection 6d.
01b97e
01b97e
  A separable portion of the object code, whose source code is excluded
01b97e
from the Corresponding Source as a System Library, need not be
01b97e
included in conveying the object code work.
01b97e
01b97e
  A "User Product" is either (1) a "consumer product", which means any
01b97e
tangible personal property which is normally used for personal, family,
01b97e
or household purposes, or (2) anything designed or sold for incorporation
01b97e
into a dwelling.  In determining whether a product is a consumer product,
01b97e
doubtful cases shall be resolved in favor of coverage.  For a particular
01b97e
product received by a particular user, "normally used" refers to a
01b97e
typical or common use of that class of product, regardless of the status
01b97e
of the particular user or of the way in which the particular user
01b97e
actually uses, or expects or is expected to use, the product.  A product
01b97e
is a consumer product regardless of whether the product has substantial
01b97e
commercial, industrial or non-consumer uses, unless such uses represent
01b97e
the only significant mode of use of the product.
01b97e
01b97e
  "Installation Information" for a User Product means any methods,
01b97e
procedures, authorization keys, or other information required to install
01b97e
and execute modified versions of a covered work in that User Product from
01b97e
a modified version of its Corresponding Source.  The information must
01b97e
suffice to ensure that the continued functioning of the modified object
01b97e
code is in no case prevented or interfered with solely because
01b97e
modification has been made.
01b97e
01b97e
  If you convey an object code work under this section in, or with, or
01b97e
specifically for use in, a User Product, and the conveying occurs as
01b97e
part of a transaction in which the right of possession and use of the
01b97e
User Product is transferred to the recipient in perpetuity or for a
01b97e
fixed term (regardless of how the transaction is characterized), the
01b97e
Corresponding Source conveyed under this section must be accompanied
01b97e
by the Installation Information.  But this requirement does not apply
01b97e
if neither you nor any third party retains the ability to install
01b97e
modified object code on the User Product (for example, the work has
01b97e
been installed in ROM).
01b97e
01b97e
  The requirement to provide Installation Information does not include a
01b97e
requirement to continue to provide support service, warranty, or updates
01b97e
for a work that has been modified or installed by the recipient, or for
01b97e
the User Product in which it has been modified or installed.  Access to a
01b97e
network may be denied when the modification itself materially and
01b97e
adversely affects the operation of the network or violates the rules and
01b97e
protocols for communication across the network.
01b97e
01b97e
  Corresponding Source conveyed, and Installation Information provided,
01b97e
in accord with this section must be in a format that is publicly
01b97e
documented (and with an implementation available to the public in
01b97e
source code form), and must require no special password or key for
01b97e
unpacking, reading or copying.
01b97e
01b97e
  7. Additional Terms.
01b97e
01b97e
  "Additional permissions" are terms that supplement the terms of this
01b97e
License by making exceptions from one or more of its conditions.
01b97e
Additional permissions that are applicable to the entire Program shall
01b97e
be treated as though they were included in this License, to the extent
01b97e
that they are valid under applicable law.  If additional permissions
01b97e
apply only to part of the Program, that part may be used separately
01b97e
under those permissions, but the entire Program remains governed by
01b97e
this License without regard to the additional permissions.
01b97e
01b97e
  When you convey a copy of a covered work, you may at your option
01b97e
remove any additional permissions from that copy, or from any part of
01b97e
it.  (Additional permissions may be written to require their own
01b97e
removal in certain cases when you modify the work.)  You may place
01b97e
additional permissions on material, added by you to a covered work,
01b97e
for which you have or can give appropriate copyright permission.
01b97e
01b97e
  Notwithstanding any other provision of this License, for material you
01b97e
add to a covered work, you may (if authorized by the copyright holders of
01b97e
that material) supplement the terms of this License with terms:
01b97e
01b97e
    a) Disclaiming warranty or limiting liability differently from the
01b97e
    terms of sections 15 and 16 of this License; or
01b97e
01b97e
    b) Requiring preservation of specified reasonable legal notices or
01b97e
    author attributions in that material or in the Appropriate Legal
01b97e
    Notices displayed by works containing it; or
01b97e
01b97e
    c) Prohibiting misrepresentation of the origin of that material, or
01b97e
    requiring that modified versions of such material be marked in
01b97e
    reasonable ways as different from the original version; or
01b97e
01b97e
    d) Limiting the use for publicity purposes of names of licensors or
01b97e
    authors of the material; or
01b97e
01b97e
    e) Declining to grant rights under trademark law for use of some
01b97e
    trade names, trademarks, or service marks; or
01b97e
01b97e
    f) Requiring indemnification of licensors and authors of that
01b97e
    material by anyone who conveys the material (or modified versions of
01b97e
    it) with contractual assumptions of liability to the recipient, for
01b97e
    any liability that these contractual assumptions directly impose on
01b97e
    those licensors and authors.
01b97e
01b97e
  All other non-permissive additional terms are considered "further
01b97e
restrictions" within the meaning of section 10.  If the Program as you
01b97e
received it, or any part of it, contains a notice stating that it is
01b97e
governed by this License along with a term that is a further
01b97e
restriction, you may remove that term.  If a license document contains
01b97e
a further restriction but permits relicensing or conveying under this
01b97e
License, you may add to a covered work material governed by the terms
01b97e
of that license document, provided that the further restriction does
01b97e
not survive such relicensing or conveying.
01b97e
01b97e
  If you add terms to a covered work in accord with this section, you
01b97e
must place, in the relevant source files, a statement of the
01b97e
additional terms that apply to those files, or a notice indicating
01b97e
where to find the applicable terms.
01b97e
01b97e
  Additional terms, permissive or non-permissive, may be stated in the
01b97e
form of a separately written license, or stated as exceptions;
01b97e
the above requirements apply either way.
01b97e
01b97e
  8. Termination.
01b97e
01b97e
  You may not propagate or modify a covered work except as expressly
01b97e
provided under this License.  Any attempt otherwise to propagate or
01b97e
modify it is void, and will automatically terminate your rights under
01b97e
this License (including any patent licenses granted under the third
01b97e
paragraph of section 11).
01b97e
01b97e
  However, if you cease all violation of this License, then your
01b97e
license from a particular copyright holder is reinstated (a)
01b97e
provisionally, unless and until the copyright holder explicitly and
01b97e
finally terminates your license, and (b) permanently, if the copyright
01b97e
holder fails to notify you of the violation by some reasonable means
01b97e
prior to 60 days after the cessation.
01b97e
01b97e
  Moreover, your license from a particular copyright holder is
01b97e
reinstated permanently if the copyright holder notifies you of the
01b97e
violation by some reasonable means, this is the first time you have
01b97e
received notice of violation of this License (for any work) from that
01b97e
copyright holder, and you cure the violation prior to 30 days after
01b97e
your receipt of the notice.
01b97e
01b97e
  Termination of your rights under this section does not terminate the
01b97e
licenses of parties who have received copies or rights from you under
01b97e
this License.  If your rights have been terminated and not permanently
01b97e
reinstated, you do not qualify to receive new licenses for the same
01b97e
material under section 10.
01b97e
01b97e
  9. Acceptance Not Required for Having Copies.
01b97e
01b97e
  You are not required to accept this License in order to receive or
01b97e
run a copy of the Program.  Ancillary propagation of a covered work
01b97e
occurring solely as a consequence of using peer-to-peer transmission
01b97e
to receive a copy likewise does not require acceptance.  However,
01b97e
nothing other than this License grants you permission to propagate or
01b97e
modify any covered work.  These actions infringe copyright if you do
01b97e
not accept this License.  Therefore, by modifying or propagating a
01b97e
covered work, you indicate your acceptance of this License to do so.
01b97e
01b97e
  10. Automatic Licensing of Downstream Recipients.
01b97e
01b97e
  Each time you convey a covered work, the recipient automatically
01b97e
receives a license from the original licensors, to run, modify and
01b97e
propagate that work, subject to this License.  You are not responsible
01b97e
for enforcing compliance by third parties with this License.
01b97e
01b97e
  An "entity transaction" is a transaction transferring control of an
01b97e
organization, or substantially all assets of one, or subdividing an
01b97e
organization, or merging organizations.  If propagation of a covered
01b97e
work results from an entity transaction, each party to that
01b97e
transaction who receives a copy of the work also receives whatever
01b97e
licenses to the work the party's predecessor in interest had or could
01b97e
give under the previous paragraph, plus a right to possession of the
01b97e
Corresponding Source of the work from the predecessor in interest, if
01b97e
the predecessor has it or can get it with reasonable efforts.
01b97e
01b97e
  You may not impose any further restrictions on the exercise of the
01b97e
rights granted or affirmed under this License.  For example, you may
01b97e
not impose a license fee, royalty, or other charge for exercise of
01b97e
rights granted under this License, and you may not initiate litigation
01b97e
(including a cross-claim or counterclaim in a lawsuit) alleging that
01b97e
any patent claim is infringed by making, using, selling, offering for
01b97e
sale, or importing the Program or any portion of it.
01b97e
01b97e
  11. Patents.
01b97e
01b97e
  A "contributor" is a copyright holder who authorizes use under this
01b97e
License of the Program or a work on which the Program is based.  The
01b97e
work thus licensed is called the contributor's "contributor version".
01b97e
01b97e
  A contributor's "essential patent claims" are all patent claims
01b97e
owned or controlled by the contributor, whether already acquired or
01b97e
hereafter acquired, that would be infringed by some manner, permitted
01b97e
by this License, of making, using, or selling its contributor version,
01b97e
but do not include claims that would be infringed only as a
01b97e
consequence of further modification of the contributor version.  For
01b97e
purposes of this definition, "control" includes the right to grant
01b97e
patent sublicenses in a manner consistent with the requirements of
01b97e
this License.
01b97e
01b97e
  Each contributor grants you a non-exclusive, worldwide, royalty-free
01b97e
patent license under the contributor's essential patent claims, to
01b97e
make, use, sell, offer for sale, import and otherwise run, modify and
01b97e
propagate the contents of its contributor version.
01b97e
01b97e
  In the following three paragraphs, a "patent license" is any express
01b97e
agreement or commitment, however denominated, not to enforce a patent
01b97e
(such as an express permission to practice a patent or covenant not to
01b97e
sue for patent infringement).  To "grant" such a patent license to a
01b97e
party means to make such an agreement or commitment not to enforce a
01b97e
patent against the party.
01b97e
01b97e
  If you convey a covered work, knowingly relying on a patent license,
01b97e
and the Corresponding Source of the work is not available for anyone
01b97e
to copy, free of charge and under the terms of this License, through a
01b97e
publicly available network server or other readily accessible means,
01b97e
then you must either (1) cause the Corresponding Source to be so
01b97e
available, or (2) arrange to deprive yourself of the benefit of the
01b97e
patent license for this particular work, or (3) arrange, in a manner
01b97e
consistent with the requirements of this License, to extend the patent
01b97e
license to downstream recipients.  "Knowingly relying" means you have
01b97e
actual knowledge that, but for the patent license, your conveying the
01b97e
covered work in a country, or your recipient's use of the covered work
01b97e
in a country, would infringe one or more identifiable patents in that
01b97e
country that you have reason to believe are valid.
01b97e
01b97e
  If, pursuant to or in connection with a single transaction or
01b97e
arrangement, you convey, or propagate by procuring conveyance of, a
01b97e
covered work, and grant a patent license to some of the parties
01b97e
receiving the covered work authorizing them to use, propagate, modify
01b97e
or convey a specific copy of the covered work, then the patent license
01b97e
you grant is automatically extended to all recipients of the covered
01b97e
work and works based on it.
01b97e
01b97e
  A patent license is "discriminatory" if it does not include within
01b97e
the scope of its coverage, prohibits the exercise of, or is
01b97e
conditioned on the non-exercise of one or more of the rights that are
01b97e
specifically granted under this License.  You may not convey a covered
01b97e
work if you are a party to an arrangement with a third party that is
01b97e
in the business of distributing software, under which you make payment
01b97e
to the third party based on the extent of your activity of conveying
01b97e
the work, and under which the third party grants, to any of the
01b97e
parties who would receive the covered work from you, a discriminatory
01b97e
patent license (a) in connection with copies of the covered work
01b97e
conveyed by you (or copies made from those copies), or (b) primarily
01b97e
for and in connection with specific products or compilations that
01b97e
contain the covered work, unless you entered into that arrangement,
01b97e
or that patent license was granted, prior to 28 March 2007.
01b97e
01b97e
  Nothing in this License shall be construed as excluding or limiting
01b97e
any implied license or other defenses to infringement that may
01b97e
otherwise be available to you under applicable patent law.
01b97e
01b97e
  12. No Surrender of Others' Freedom.
01b97e
01b97e
  If conditions are imposed on you (whether by court order, agreement or
01b97e
otherwise) that contradict the conditions of this License, they do not
01b97e
excuse you from the conditions of this License.  If you cannot convey a
01b97e
covered work so as to satisfy simultaneously your obligations under this
01b97e
License and any other pertinent obligations, then as a consequence you may
01b97e
not convey it at all.  For example, if you agree to terms that obligate you
01b97e
to collect a royalty for further conveying from those to whom you convey
01b97e
the Program, the only way you could satisfy both those terms and this
01b97e
License would be to refrain entirely from conveying the Program.
01b97e
01b97e
  13. Use with the GNU Affero General Public License.
01b97e
01b97e
  Notwithstanding any other provision of this License, you have
01b97e
permission to link or combine any covered work with a work licensed
01b97e
under version 3 of the GNU Affero General Public License into a single
01b97e
combined work, and to convey the resulting work.  The terms of this
01b97e
License will continue to apply to the part which is the covered work,
01b97e
but the special requirements of the GNU Affero General Public License,
01b97e
section 13, concerning interaction through a network will apply to the
01b97e
combination as such.
01b97e
01b97e
  14. Revised Versions of this License.
01b97e
01b97e
  The Free Software Foundation may publish revised and/or new versions of
01b97e
the GNU General Public License from time to time.  Such new versions will
01b97e
be similar in spirit to the present version, but may differ in detail to
01b97e
address new problems or concerns.
01b97e
01b97e
  Each version is given a distinguishing version number.  If the
01b97e
Program specifies that a certain numbered version of the GNU General
01b97e
Public License "or any later version" applies to it, you have the
01b97e
option of following the terms and conditions either of that numbered
01b97e
version or of any later version published by the Free Software
01b97e
Foundation.  If the Program does not specify a version number of the
01b97e
GNU General Public License, you may choose any version ever published
01b97e
by the Free Software Foundation.
01b97e
01b97e
  If the Program specifies that a proxy can decide which future
01b97e
versions of the GNU General Public License can be used, that proxy's
01b97e
public statement of acceptance of a version permanently authorizes you
01b97e
to choose that version for the Program.
01b97e
01b97e
  Later license versions may give you additional or different
01b97e
permissions.  However, no additional obligations are imposed on any
01b97e
author or copyright holder as a result of your choosing to follow a
01b97e
later version.
01b97e
01b97e
  15. Disclaimer of Warranty.
01b97e
01b97e
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
01b97e
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
01b97e
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
01b97e
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
01b97e
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
01b97e
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
01b97e
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
01b97e
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
01b97e
01b97e
  16. Limitation of Liability.
01b97e
01b97e
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
01b97e
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
01b97e
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
01b97e
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
01b97e
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
01b97e
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
01b97e
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
01b97e
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
01b97e
SUCH DAMAGES.
01b97e
01b97e
  17. Interpretation of Sections 15 and 16.
01b97e
01b97e
  If the disclaimer of warranty and limitation of liability provided
01b97e
above cannot be given local legal effect according to their terms,
01b97e
reviewing courts shall apply local law that most closely approximates
01b97e
an absolute waiver of all civil liability in connection with the
01b97e
Program, unless a warranty or assumption of liability accompanies a
01b97e
copy of the Program in return for a fee.
01b97e
01b97e
                     END OF TERMS AND CONDITIONS
01b97e
01b97e
            How to Apply These Terms to Your New Programs
01b97e
01b97e
  If you develop a new program, and you want it to be of the greatest
01b97e
possible use to the public, the best way to achieve this is to make it
01b97e
free software which everyone can redistribute and change under these terms.
01b97e
01b97e
  To do so, attach the following notices to the program.  It is safest
01b97e
to attach them to the start of each source file to most effectively
01b97e
state the exclusion of warranty; and each file should have at least
01b97e
the "copyright" line and a pointer to where the full notice is found.
01b97e
01b97e
    <one line to give the program's name and a brief idea of what it does.>

    Copyright (C) <year>  <name of author>

01b97e
    it under the terms of the GNU General Public License as published by
01b97e
    the Free Software Foundation, either version 3 of the License, or
01b97e
    (at your option) any later version.
01b97e
01b97e
    This program is distributed in the hope that it will be useful,
01b97e
    but WITHOUT ANY WARRANTY; without even the implied warranty of
01b97e
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
01b97e
    GNU General Public License for more details.
01b97e
01b97e
    You should have received a copy of the GNU General Public License
01b97e
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
01b97e
01b97e
Also add information on how to contact you by electronic and paper mail.
01b97e
01b97e
  If the program does terminal interaction, make it output a short
01b97e
notice like this when it starts in an interactive mode:
01b97e
01b97e
    <program>  Copyright (C) <year>  <name of author>
01b97e
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
01b97e
    This is free software, and you are welcome to redistribute it
01b97e
    under certain conditions; type `show c' for details.
01b97e
01b97e
The hypothetical commands `show w' and `show c' should show the appropriate
01b97e
parts of the General Public License.  Of course, your program's commands
01b97e
might be different; for a GUI interface, you would use an "about box".
01b97e
01b97e
  You should also get your employer (if you work as a programmer) or school,
01b97e
if any, to sign a "copyright disclaimer" for the program, if necessary.

  The GNU General Public License does not permit incorporating your program
01b97e
into proprietary programs.  If your program is a subroutine library, you
01b97e
may consider it more useful to permit linking proprietary applications with
01b97e
the library.  If this is what you want to do, use the GNU Lesser General
