                 GNU GENERAL PUBLIC LICENSE
                  Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation,
 Inc. <http://fsf.org/> Everyone is permitted to copy and
 distribute verbatim copies of this license document, but
 changing it is not allowed.

                          Preamble

  The GNU General Public License is a free, copyleft license
for software and other kinds of works.

  The licenses for most software and other practical works
are designed to take away your freedom to share and change
the works.  By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change all
versions of a program--to make sure it remains free software
for all its users.  We, the Free Software Foundation, use
the GNU General Public License for most of our software; it
applies also to any other work released this way by its
authors.  You can apply it to your programs, too.

  When we speak of free software, we are referring to
freedom, not price.  Our General Public Licenses are
designed to make sure that you have the freedom to
distribute copies of free software (and charge for them if
you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of
it in new free programs, and that you know you can do these
things.

  To protect your rights, we need to prevent others from
denying you these rights or asking you to surrender the
rights.  Therefore, you have certain responsibilities if you
distribute copies of the software, or if you modify it:
responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program,
whether gratis or for a fee, you must pass on to the
recipients the same freedoms that you received.  You must
make sure that they, too, receive or can get the source
code.  And you must show them these terms so they know their
rights.

  Developers that use the GNU GPL protect your rights with
two steps: (1) assert copyright on the software, and (2)
offer you this License giving you legal permission to copy,
distribute and/or modify it.

  For the developers' and authors' protection, the GPL
clearly explains that there is no warranty for this free
software.  For both users' and authors' sake, the GPL
requires that modified versions be marked as changed, so
that their problems will not be attributed erroneously to
authors of previous versions.

  Some devices are designed to deny users access to install
or run modified versions of the software inside them,
although the manufacturer can do so.  This is fundamentally
incompatible with the aim of protecting users' freedom to
change the software.  The systematic pattern of such abuse
occurs in the area of products for individuals to use, which
is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the
practice for those products.  If such problems arise
substantially in other domains, we stand ready to extend
this provision to those domains in future versions of the
GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by
software patents.  States should not allow patents to
restrict development and use of software on general-purpose
computers, but in those that do, we wish to avoid the
special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL
assures that patents cannot be used to render the program
non-free.

  The precise terms and conditions for copying, distribution
and modification follow.

                    TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General
  Public License.

  "Copyright" also means copyright-like laws that apply to
other kinds of works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed
under this License.  Each licensee is addressed as "you".
"Licensees" and "recipients" may be individuals or
organizations.

  To "modify" a work means to copy from or adapt all or part
of the work in a fashion requiring copyright permission,
other than the making of an exact copy.  The resulting work
is called a "modified version" of the earlier work or a work
"based on" the earlier work.

  A "covered work" means either the unmodified Program or a
work based on the Program.

  To "propagate" a work means to do anything with it that,
without permission, would make you directly or secondarily
liable for infringement under applicable copyright law,
except executing it on a computer or modifying a private
copy.  Propagation includes copying, distribution (with or
without modification), making available to the public, and
in some countries other activities as well.

  To "convey" a work means any kind of propagation that
enables other parties to make or receive copies.  Mere
interaction with a user through a computer network, with no
transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal
Notices" to the extent that it includes a convenient and
prominently visible feature that (1) displays an appropriate
copyright notice, and (2) tells the user that there is no
warranty for the work (except to the extent that warranties
are provided), that licensees may convey the work under this
License, and how to view a copy of this License.  If the
interface presents a list of user commands or options, such
as a menu, a prominent item in the list meets this
criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of
the work for making modifications to it.  "Object code"
means any non-source form of a work.

  A "Standard Interface" means an interface that either is
an official standard defined by a recognized standards body,
or, in the case of interfaces specified for a particular
programming language, one that is widely used among
developers working in that language.

  The "System Libraries" of an executable work include
anything, other than the work as a whole, that (a) is
included in the normal form of packaging a Major Component,
but which is not part of that Major Component, and (b)
serves only to enable use of the work with that Major
Component, or to implement a Standard Interface for which an
implementation is available to the public in source code
form.  A "Major Component", in this context, means a major
essential component (kernel, window system, and so on) of
the specific operating system (if any) on which the
executable work runs, or a compiler used to produce the
work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form
means all the source code needed to generate, install, and
(for an executable work) run the object code and to modify
the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or
general-purpose tools or generally available free programs
which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding
Source includes interface definition files associated with
source files for the work, and the source code for shared
libraries and dynamically linked subprograms that the work
is specifically designed to require, such as by intimate
data communication or control flow between those subprograms
and other parts of the work.

  The Corresponding Source need not include anything that
users can regenerate automatically from other parts of the
Corresponding Source.

  The Corresponding Source for a work in source code form is
that same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the
term of copyright on the Program, and are irrevocable
provided the stated conditions are met.  This License
explicitly affirms your unlimited permission to run the
unmodified Program.  The output from running a covered work
is covered by this License only if the output, given its
content, constitutes a covered work.  This License
acknowledges your rights of fair use or other equivalent, as
provided by copyright law.

  You may make, run and propagate covered works that you do
not convey, without conditions so long as your license
otherwise remains in force.  You may convey covered works to
others for the sole purpose of having them make
modifications exclusively for you, or provide you with
facilities for running those works, provided that you comply
with the terms of this License in conveying all material for
which you do not control copyright.  Those thus making or
running the covered works for you must do so exclusively on
your behalf, under your direction and control, on terms that
prohibit them from making any copies of your copyrighted
material outside their relationship with you.

  Conveying under any other circumstances is permitted
solely under the conditions stated below.  Sublicensing is
not allowed; section 10 makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention
  Law.

  No covered work shall be deemed part of an effective
technological measure under any applicable law fulfilling
obligations under article 11 of the WIPO copyright treaty
adopted on 20 December 1996, or similar laws prohibiting or
restricting circumvention of such measures.

  When you convey a covered work, you waive any legal power
to forbid circumvention of technological measures to the
extent such circumvention is effected by exercising rights
under this License with respect to the covered work, and you
disclaim any intention to limit operation or modification of
the work as a means of enforcing, against the work's users,
your or third parties' legal rights to forbid circumvention
of technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source
code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an
appropriate copyright notice; keep intact all notices
stating that this License and any non-permissive terms added
in accord with section 7 apply to the code; keep intact all
notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that
you convey, and you may offer support or warranty protection
for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the
modifications to produce it from the Program, in the form of
source code under the terms of section 4, provided that you
also meet all of these conditions:

    a) The work must carry prominent notices stating that
    you modified it, and giving a relevant date.

    b) The work must carry prominent notices stating that it
    is released under this License and any conditions added
    under section 7.  This requirement modifies the
    requirement in section 4 to "keep intact all notices".

    c) You must license the entire work, as a whole, under
    this License to anyone who comes into possession of a
    copy.  This License will therefore apply, along with any
    applicable section 7 additional terms, to the whole of
    the work, and all its parts, regardless of how they are
    packaged.  This License gives no permission to license
    the work in any other way, but it does not invalidate
    such permission if you have separately received it.

    d) If the work has interactive user interfaces, each
    must display Appropriate Legal Notices; however, if the
    Program has interactive interfaces that do not display
    Appropriate Legal Notices, your work need not make them
    do so.

  A compilation of a covered work with other separate and
independent works, which are not by their nature extensions
of the covered work, and which are not combined with it such
as to form a larger program, in or on a volume of a storage
or distribution medium, is called an "aggregate" if the
compilation and its resulting copyright are not used to
limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a
covered work in an aggregate does not cause this License to
apply to the other parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under
the terms of sections 4 and 5, provided that you also convey
the machine-readable Corresponding Source under the terms of
this License, in one of these ways:

    a) Convey the object code in, or embodied in, a physical
    product (including a physical distribution medium),
    accompanied by the Corresponding Source fixed on a
    durable physical medium customarily used for software
    interchange.

    b) Convey the object code in, or embodied in, a physical
    product (including a physical distribution medium),
    accompanied by a written offer, valid for at least three
    years and valid for as long as you offer spare parts or
    customer support for that product model, to give anyone
    who possesses the object code either (1) a copy of the
    Corresponding Source for all the software in the product
    that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a
    price no more than your reasonable cost of physically
    performing this conveying of source, or (2) access to
    copy the Corresponding Source from a network server at
    no charge.

    c) Convey individual copies of the object code with a
    copy of the written offer to provide the Corresponding
    Source.  This alternative is allowed only occasionally
    and noncommercially, and only if you received the object
    code with such an offer, in accord with subsection 6b.

    d) Convey the object code by offering access from a
    designated place (gratis or for a charge), and offer
    equivalent access to the Corresponding Source in the
    same way through the same place at no further charge.
    You need not require recipients to copy the
    Corresponding Source along with the object code.  If the
    place to copy the object code is a network server, the
    Corresponding Source may be on a different server
    (operated by you or a third party) that supports
    equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to
    find the Corresponding Source.  Regardless of what
    server hosts the Corresponding Source, you remain
    obligated to ensure that it is available for as long as
    needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer
    transmission, provided you inform other peers where the
    object code and Corresponding Source of the work are
    being offered to the general public at no charge under
    subsection 6d.

  A separable portion of the object code, whose source code
is excluded from the Corresponding Source as a System
Library, need not be included in conveying the object code
work.

  A "User Product" is either (1) a "consumer product", which
means any tangible personal property which is normally used
for personal, family, or household purposes, or (2) anything
designed or sold for incorporation into a dwelling.  In
determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For
a particular product received by a particular user,
"normally used" refers to a typical or common use of that
class of product, regardless of the status of the particular
user or of the way in which the particular user actually
uses, or expects or is expected to use, the product.  A
product is a consumer product regardless of whether the
product has substantial commercial, industrial or
non-consumer uses, unless such uses represent the only
significant mode of use of the product.

  "Installation Information" for a User Product means any
methods, procedures, authorization keys, or other
information required to install and execute modified
versions of a covered work in that User Product from a
modified version of its Corresponding Source.  The
information must suffice to ensure that the continued
functioning of the modified object code is in no case
prevented or interfered with solely because modification has
been made.

  If you convey an object code work under this section in,
or with, or specifically for use in, a User Product, and the
conveying occurs as part of a transaction in which the right
of possession and use of the User Product is transferred to
the recipient in perpetuity or for a fixed term (regardless
of how the transaction is characterized), the Corresponding
Source conveyed under this section must be accompanied by
the Installation Information.  But this requirement does not
apply if neither you nor any third party retains the ability
to install modified object code on the User Product (for
example, the work has been installed in ROM).

  The requirement to provide Installation Information does
not include a requirement to continue to provide support
service, warranty, or updates for a work that has been
modified or installed by the recipient, or for the User
Product in which it has been modified or installed.  Access
to a network may be denied when the modification itself
materially and adversely affects the operation of the
network or violates the rules and protocols for
communication across the network.

  Corresponding Source conveyed, and Installation
Information provided, in accord with this section must be in
a format that is publicly documented (and with an
implementation available to the public in source code form),
and must require no special password or key for unpacking,
reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the
terms of this License by making exceptions from one or more
of its conditions.  Additional permissions that are
applicable to the entire Program shall be treated as though
they were included in this License, to the extent that they
are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used
separately under those permissions, but the entire Program
remains governed by this License without regard to the
additional permissions.

  When you convey a copy of a covered work, you may at your
option remove any additional permissions from that copy, or
from any part of it.  (Additional permissions may be written
to require their own removal in certain cases when you
modify the work.)  You may place additional permissions on
material, added by you to a covered work, for which you have
or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for
material you add to a covered work, you may (if authorized
by the copyright holders of that material) supplement the
terms of this License with terms:

    a) Disclaiming warranty or limiting liability
    differently from the terms of sections 15 and 16 of this
    License; or

    b) Requiring preservation of specified reasonable legal
    notices or author attributions in that material or in
    the Appropriate Legal Notices displayed by works
    containing it; or

    c) Prohibiting misrepresentation of the origin of that
    material, or requiring that modified versions of such
    material be marked in reasonable ways as different from
    the original version; or

    d) Limiting the use for publicity purposes of names of
    licensors or authors of the material; or

    e) Declining to grant rights under trademark law for use
    of some trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of
    that material by anyone who conveys the material (or
    modified versions of it) with contractual assumptions of
    liability to the recipient, for any liability that these
    contractual assumptions directly impose on those
    licensors and authors.

  All other non-permissive additional terms are considered
"further restrictions" within the meaning of section 10.  If
the Program as you received it, or any part of it, contains
a notice stating that it is governed by this License along
with a term that is a further restriction, you may remove
that term.  If a license document contains a further
restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by
the terms of that license document, provided that the
further restriction does not survive such relicensing or
conveying.

  If you add terms to a covered work in accord with this
section, you must place, in the relevant source files, a
statement of the additional terms that apply to those files,
or a notice indicating where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be
stated in the form of a separately written license, or
stated as exceptions; the above requirements apply either
way.

  8. Termination.

  You may not propagate or modify a covered work except as
expressly provided under this License.  Any attempt
otherwise to propagate or modify it is void, and will
automatically terminate your rights under this License
(including any patent licenses granted under the third
paragraph of section 11).

  However, if you cease all violation of this License, then
your license from a particular copyright holder is
reinstated (a) provisionally, unless and until the copyright
holder explicitly and finally terminates your license, and
(b) permanently, if the copyright holder fails to notify you
of the violation by some reasonable means prior to 60 days
after the cessation.

  Moreover, your license from a particular copyright holder
is reinstated permanently if the copyright holder notifies
you of the violation by some reasonable means, this is the
first time you have received notice of violation of this
License (for any work) from that copyright holder, and you
cure the violation prior to 30 days after your receipt of
the notice.

  Termination of your rights under this section does not
terminate the licenses of parties who have received copies
or rights from you under this License.  If your rights have
been terminated and not permanently reinstated, you do not
qualify to receive new licenses for the same material under
section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to
receive or run a copy of the Program.  Ancillary propagation
of a covered work occurring solely as a consequence of using
peer-to-peer transmission to receive a copy likewise does
not require acceptance.  However, nothing other than this
License grants you permission to propagate or modify any
covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or
propagating a covered work, you indicate your acceptance of
this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient
automatically receives a license from the original
licensors, to run, modify and propagate that work, subject
to this License.  You are not responsible for enforcing
compliance by third parties with this License.

  An "entity transaction" is a transaction transferring
control of an organization, or substantially all assets of
one, or subdividing an organization, or merging
organizations.  If propagation of a covered work results
from an entity transaction, each party to that transaction
who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had
or could give under the previous paragraph, plus a right to
possession of the Corresponding Source of the work from the
predecessor in interest, if the predecessor has it or can
get it with reasonable efforts.

  You may not impose any further restrictions on the
exercise of the rights granted or affirmed under this
License.  For example, you may not impose a license fee,
royalty, or other charge for exercise of rights granted
under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit)
alleging that any patent claim is infringed by making,
using, selling, offering for sale, or importing the Program
or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use
under this License of the Program or a work on which the
Program is based.  The work thus licensed is called the
contributor's "contributor version".

  A contributor's "essential patent claims" are all patent
claims owned or controlled by the contributor, whether
already acquired or hereafter acquired, that would be
infringed by some manner, permitted by this License, of
making, using, or selling its contributor version, but do
not include claims that would be infringed only as a
consequence of further modification of the contributor
version.  For purposes of this definition, "control"
includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.

  Each contributor grants you a non-exclusive, worldwide,
royalty-free patent license under the contributor's
essential patent claims, to make, use, sell, offer for sale,
import and otherwise run, modify and propagate the contents
of its contributor version.

  In the following three paragraphs, a "patent license" is
any express agreement or commitment, however denominated,
not to enforce a patent (such as an express permission to
practice a patent or covenant not to sue for patent
infringement).  To "grant" such a patent license to a party
means to make such an agreement or commitment not to enforce
a patent against the party.

  If you convey a covered work, knowingly relying on a
patent license, and the Corresponding Source of the work is
not available for anyone to copy, free of charge and under
the terms of this License, through a publicly available
network server or other readily accessible means, then you
must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit
of the patent license for this particular work, or (3)
arrange, in a manner consistent with the requirements of
this License, to extend the patent license to downstream
recipients.  "Knowingly relying" means you have actual
knowledge that, but for the patent license, your conveying
the covered work in a country, or your recipient's use of
the covered work in a country, would infringe one or more
identifiable patents in that country that you have reason to
believe are valid.

  If, pursuant to or in connection with a single transaction
or arrangement, you convey, or propagate by procuring
conveyance of, a covered work, and grant a patent license to
some of the parties receiving the covered work authorizing
them to use, propagate, modify or convey a specific copy of
the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work
and works based on it.

  A patent license is "discriminatory" if it does not
include within the scope of its coverage, prohibits the
exercise of, or is conditioned on the non-exercise of one or
more of the rights that are specifically granted under this
License.  You may not convey a covered work if you are a
party to an arrangement with a third party that is in the
business of distributing software, under which you make
payment to the third party based on the extent of your
activity of conveying the work, and under which the third
party grants, to any of the parties who would receive the
covered work from you, a discriminatory patent license (a)
in connection with copies of the covered work conveyed by
you (or copies made from those copies), or (b) primarily for
and in connection with specific products or compilations
that contain the covered work, unless you entered into that
arrangement, or that patent license was granted, prior to 28
March 2007.

  Nothing in this License shall be construed as excluding or
limiting any implied license or other defenses to
infringement that may otherwise be available to you under
applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of
this License, they do not excuse you from the conditions of
this License.  If you cannot convey a covered work so as to
satisfy simultaneously your obligations under this License
and any other pertinent obligations, then as a consequence
you may not convey it at all.  For example, if you agree to
terms that obligate you to collect a royalty for further
conveying from those to whom you convey the Program, the
only way you could satisfy both those terms and this License
would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you
have permission to link or combine any covered work with a
work licensed under version 3 of the GNU Affero General
Public License into a single combined work, and to convey
the resulting work.  The terms of this License will continue
to apply to the part which is the covered work, but the
special requirements of the GNU Affero General Public
License, section 13, concerning interaction through a
network will apply to the combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or
new versions of the GNU General Public License from time to
time.  Such new versions will be similar in spirit to the
present version, but may differ in detail to address new
problems or concerns.

  Each version is given a distinguishing version number.  If
the Program specifies that a certain numbered version of the
GNU General Public License "or any later version" applies to
it, you have the option of following the terms and
conditions either of that numbered version or of any later
version published by the Free Software Foundation.  If the
Program does not specify a version number of the GNU General
Public License, you may choose any version ever published by
the Free Software Foundation.

  If the Program specifies that a proxy can decide which
future versions of the GNU General Public License can be
used, that proxy's public statement of acceptance of a
version permanently authorizes you to choose that version
for the Program.

  Later license versions may give you additional or
different permissions.  However, no additional obligations
are imposed on any author or copyright holder as a result of
your choosing to follow a later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT
PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED
IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO
IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO
MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability
provided above cannot be given local legal effect according
to their terms, reviewing courts shall apply local law that
most closely approximates an absolute waiver of all civil
liability in connection with the Program, unless a warranty
or assumption of liability accompanies a copy of the Program
in return for a fee.

                END OF TERMS AND CONDITIONS

       How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the
greatest possible use to the public, the best way to achieve
this is to make it free software which everyone can
redistribute and change under these terms.

  To do so, attach the following notices to the program.  It
is safest to attach them to the start of each source file to
most effectively state the exclusion of warranty; and each
file should have at least the "copyright" line and a pointer
to where the full notice is found.

    <one line to give the program's name and a brief idea of
    what it does.> Copyright (C) <year> <name of author>

    This program is free software: you can redistribute it
    and/or modify it under the terms of the GNU General
    Public License as published by the Free Software
    Foundation, either version 3 of the License, or (at your
    option) any later version.

    This program is distributed in the hope that it will be
    useful, but WITHOUT ANY WARRANTY; without even the

  If the program does terminal interaction, make it output a
short notice like this when it starts in an interactive
mode:

    <program> Copyright (C) <year> <name of author> This
    program comes with ABSOLUTELY NO WARRANTY; for details
    type `show w'.  This is free software, and you are
    welcome to redistribute it under certain conditions;
    type `show c' for details.

The hypothetical commands `show w' and `show c' should show
the appropriate parts of the General Public License.  Of
course, your program's commands might be different; for a
GUI interface, you would use an "about box".

  You should also get your employer (if you work as a
programmer) or school, if any, to sign a "copyright
disclaimer" for the program, if necessary.  For more
information on this, and how to apply and follow the GNU
GPL, see <http://www.gnu.org/licenses/>.

  The GNU General Public License does not permit
incorporating your program into proprietary programs.  If
your program is a subroutine library, you may consider it
more useful to permit linking proprietary applications with
the library.  If this is what you want to do, use the GNU
Lesser General Public License instead of this License.  But
first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
