                    GNU GENERAL PUBLIC LICENSE













                       Version 3, 29 June 2007



























 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>













 Everyone is permitted to copy and distribute verbatim copies













 of this license document, but changing it is not allowed.



























                            Preamble



























  The GNU General Public License is a free, copyleft license for













software and other kinds of works.



























  The licenses for most software and other practical works are designed













to take away your freedom to share and change the works.  By contrast,













the GNU General Public License is intended to guarantee your freedom to













share and change all versions of a program--to make sure it remains free













software for all its users.  We, the Free Software Foundation, use the













GNU General Public License for most of our software; it applies also to













any other work released this way by its authors.  You can apply it to













your programs, too.



























  When we speak of free software, we are referring to freedom, not













price.  Our General Public Licenses are designed to make sure that you













have the freedom to distribute copies of free software (and charge for













them if you wish), that you receive source code or can get it if you













want it, that you can change the software or use pieces of it in new













free programs, and that you know you can do these things.



























  To protect your rights, we need to prevent others from denying you













these rights or asking you to surrender the rights.  Therefore, you have













certain responsibilities if you distribute copies of the software, or if













you modify it: responsibilities to respect the freedom of others.



























  For example, if you distribute copies of such a program, whether













gratis or for a fee, you must pass on to the recipients the same













freedoms that you received.  You must make sure that they, too, receive













or can get the source code.  And you must show them these terms so they













know their rights.



























  Developers that use the GNU GPL protect your rights with two steps:













(1) assert copyright on the software, and (2) offer you this License













giving you legal permission to copy, distribute and/or modify it.



























  For the developers' and authors' protection, the GPL clearly explains













that there is no warranty for this free software.  For both users' and













authors' sake, the GPL requires that modified versions be marked as













changed, so that their problems will not be attributed erroneously to













authors of previous versions.



























  Some devices are designed to deny users access to install or run













modified versions of the software inside them, although the manufacturer













can do so.  This is fundamentally incompatible with the aim of













protecting users' freedom to change the software.  The systematic













pattern of such abuse occurs in the area of products for individuals to













use, which is precisely where it is most unacceptable.  Therefore, we













have designed this version of the GPL to prohibit the practice for those













products.  If such problems arise substantially in other domains, we













stand ready to extend this provision to those domains in future versions













of the GPL, as needed to protect the freedom of users.



























  Finally, every program is threatened constantly by software patents.













States should not allow patents to restrict development and use of













software on general-purpose computers, but in those that do, we wish to













avoid the special danger that patents applied to a free program could













make it effectively proprietary.  To prevent this, the GPL assures that













patents cannot be used to render the program non-free.



























  The precise terms and conditions for copying, distribution and













modification follow.



























                       TERMS AND CONDITIONS



























  0. Definitions.



























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



























  "Copyright" also means copyright-like laws that apply to other kinds of













works, such as semiconductor masks.



























  "The Program" refers to any copyrightable work licensed under this













License.  Each licensee is addressed as "you".  "Licensees" and













"recipients" may be individuals or organizations.



























  To "modify" a work means to copy from or adapt all or part of the work













in a fashion requiring copyright permission, other than the making of an













exact copy.  The resulting work is called a "modified version" of the













earlier work or a work "based on" the earlier work.



























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













on the Program.



























  To "propagate" a work means to do anything with it that, without













permission, would make you directly or secondarily liable for













infringement under applicable copyright law, except executing it on a













computer or modifying a private copy.  Propagation includes copying,













distribution (with or without modification), making available to the













public, and in some countries other activities as well.



























  To "convey" a work means any kind of propagation that enables other













parties to make or receive copies.  Mere interaction with a user through













a computer network, with no transfer of a copy, is not conveying.



























  An interactive user interface displays "Appropriate Legal Notices"













to the extent that it includes a convenient and prominently visible













feature that (1) displays an appropriate copyright notice, and (2)













tells the user that there is no warranty for the work (except to the













extent that warranties are provided), that licensees may convey the













work under this License, and how to view a copy of this License.  If













the interface presents a list of user commands or options, such as a













menu, a prominent item in the list meets this criterion.



























  1. Source Code.



























  The "source code" for a work means the preferred form of the work













for making modifications to it.  "Object code" means any non-source













form of a work.



























  A "Standard Interface" means an interface that either is an official













standard defined by a recognized standards body, or, in the case of













interfaces specified for a particular programming language, one that













is widely used among developers working in that language.



























  The "System Libraries" of an executable work include anything, other













than the work as a whole, that (a) is included in the normal form of













packaging a Major Component, but which is not part of that Major













Component, and (b) serves only to enable use of the work with that













Major Component, or to implement a Standard Interface for which an













implementation is available to the public in source code form.  A













"Major Component", in this context, means a major essential component













(kernel, window system, and so on) of the specific operating system













(if any) on which the executable work runs, or a compiler used to













produce the work, or an object code interpreter used to run it.



























  The "Corresponding Source" for a work in object code form means all













the source code needed to generate, install, and (for an executable













work) run the object code and to modify the work, including scripts to













control those activities.  However, it does not include the work's













System Libraries, or general-purpose tools or generally available free













programs which are used unmodified in performing those activities but













which are not part of the work.  For example, Corresponding Source













includes interface definition files associated with source files for













the work, and the source code for shared libraries and dynamically













linked subprograms that the work is specifically designed to require,













such as by intimate data communication or control flow between those













subprograms and other parts of the work.



























  The Corresponding Source need not include anything that users













can regenerate automatically from other parts of the Corresponding













Source.



























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













same work.



























  2. Basic Permissions.



























  All rights granted under this License are granted for the term of













copyright on the Program, and are irrevocable provided the stated













conditions are met.  This License explicitly affirms your unlimited













permission to run the unmodified Program.  The output from running a













covered work is covered by this License only if the output, given its













content, constitutes a covered work.  This License acknowledges your













rights of fair use or other equivalent, as provided by copyright law.



























  You may make, run and propagate covered works that you do not













convey, without conditions so long as your license otherwise remains













in force.  You may convey covered works to others for the sole purpose













of having them make modifications exclusively for you, or provide you













with facilities for running those works, provided that you comply with













the terms of this License in conveying all material for which you do













not control copyright.  Those thus making or running the covered works













for you must do so exclusively on your behalf, under your direction













and control, on terms that prohibit them from making any copies of













your copyrighted material outside their relationship with you.



























  Conveying under any other circumstances is permitted solely under













the conditions stated below.  Sublicensing is not allowed; section 10













makes it unnecessary.



























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



























  No covered work shall be deemed part of an effective technological













measure under any applicable law fulfilling obligations under article













11 of the WIPO copyright treaty adopted on 20 December 1996, or













similar laws prohibiting or restricting circumvention of such













measures.



























  When you convey a covered work, you waive any legal power to forbid













circumvention of technological measures to the extent such circumvention













is effected by exercising rights under this License with respect to













the covered work, and you disclaim any intention to limit operation or













modification of the work as a means of enforcing, against the work's













users, your or third parties' legal rights to forbid circumvention of













technological measures.



























  4. Conveying Verbatim Copies.



























  You may convey verbatim copies of the Program's source code as you













receive it, in any medium, provided that you conspicuously and













appropriately publish on each copy an appropriate copyright notice;













keep intact all notices stating that this License and any













non-permissive terms added in accord with section 7 apply to the code;













keep intact all notices of the absence of any warranty; and give all













recipients a copy of this License along with the Program.



























  You may charge any price or no price for each copy that you convey,













and you may offer support or warranty protection for a fee.



























  5. Conveying Modified Source Versions.



























  You may convey a work based on the Program, or the modifications to













produce it from the Program, in the form of source code under the













terms of section 4, provided that you also meet all of these conditions:



























    a) The work must carry prominent notices stating that you modified













    it, and giving a relevant date.



























    b) The work must carry prominent notices stating that it is













    released under this License and any conditions added under section













    7.  This requirement modifies the requirement in section 4 to













    "keep intact all notices".



























    c) You must license the entire work, as a whole, under this













    License to anyone who comes into possession of a copy.  This













    License will therefore apply, along with any applicable section 7













    additional terms, to the whole of the work, and all its parts,













    regardless of how they are packaged.  This License gives no













    permission to license the work in any other way, but it does not













    invalidate such permission if you have separately received it.



























    d) If the work has interactive user interfaces, each must display













    Appropriate Legal Notices; however, if the Program has interactive













    interfaces that do not display Appropriate Legal Notices, your













    work need not make them do so.



























  A compilation of a covered work with other separate and independent













works, which are not by their nature extensions of the covered work,













and which are not combined with it such as to form a larger program,













in or on a volume of a storage or distribution medium, is called an













"aggregate" if the compilation and its resulting copyright are not













used to limit the access or legal rights of the compilation's users













beyond what the individual works permit.  Inclusion of a covered work













in an aggregate does not cause this License to apply to the other













parts of the aggregate.



























  6. Conveying Non-Source Forms.



























  You may convey a covered work in object code form under the terms













of sections 4 and 5, provided that you also convey the













machine-readable Corresponding Source under the terms of this License,













in one of these ways:



























    a) Convey the object code in, or embodied in, a physical product













    (including a physical distribution medium), accompanied by the













    Corresponding Source fixed on a durable physical medium













    customarily used for software interchange.



























    b) Convey the object code in, or embodied in, a physical product













    (including a physical distribution medium), accompanied by a













    written offer, valid for at least three years and valid for as













    long as you offer spare parts or customer support for that product













    model, to give anyone who possesses the object code either (1) a













    copy of the Corresponding Source for all the software in the













    product that is covered by this License, on a durable physical













    medium customarily used for software interchange, for a price no













    more than your reasonable cost of physically performing this













    conveying of source, or (2) access to copy the













    Corresponding Source from a network server at no charge.



























    c) Convey individual copies of the object code with a copy of the













    written offer to provide the Corresponding Source.  This













    alternative is allowed only occasionally and noncommercially, and













    only if you received the object code with such an offer, in accord













    with subsection 6b.



























    d) Convey the object code by offering access from a designated













    place (gratis or for a charge), and offer equivalent access to the













    Corresponding Source in the same way through the same place at no













    further charge.  You need not require recipients to copy the













    Corresponding Source along with the object code.  If the place to













    copy the object code is a network server, the Corresponding Source













    may be on a different server (operated by you or a third party)













    that supports equivalent copying facilities, provided you maintain













    clear directions next to the object code saying where to find the













    Corresponding Source.  Regardless of what server hosts the













    Corresponding Source, you remain obligated to ensure that it is













    available for as long as needed to satisfy these requirements.



























    e) Convey the object code using peer-to-peer transmission, provided













    you inform other peers where the object code and Corresponding













    Source of the work are being offered to the general public at no













    charge under subsection 6d.



























  A separable portion of the object code, whose source code is excluded













from the Corresponding Source as a System Library, need not be













included in conveying the object code work.



























  A "User Product" is either (1) a "consumer product", which means any













tangible personal property which is normally used for personal, family,













or household purposes, or (2) anything designed or sold for incorporation













into a dwelling.  In determining whether a product is a consumer product,













doubtful cases shall be resolved in favor of coverage.  For a particular













product received by a particular user, "normally used" refers to a













typical or common use of that class of product, regardless of the status













of the particular user or of the way in which the particular user













actually uses, or expects or is expected to use, the product.  A product













is a consumer product regardless of whether the product has substantial













commercial, industrial or non-consumer uses, unless such uses represent













the only significant mode of use of the product.



























  "Installation Information" for a User Product means any methods,













procedures, authorization keys, or other information required to install













and execute modified versions of a covered work in that User Product from













a modified version of its Corresponding Source.  The information must













suffice to ensure that the continued functioning of the modified object













code is in no case prevented or interfered with solely because













modification has been made.



























  If you convey an object code work under this section in, or with, or













specifically for use in, a User Product, and the conveying occurs as













part of a transaction in which the right of possession and use of the













User Product is transferred to the recipient in perpetuity or for a













fixed term (regardless of how the transaction is characterized), the













Corresponding Source conveyed under this section must be accompanied













by the Installation Information.  But this requirement does not apply













if neither you nor any third party retains the ability to install













modified object code on the User Product (for example, the work has













been installed in ROM).



























  The requirement to provide Installation Information does not include a













requirement to continue to provide support service, warranty, or updates













for a work that has been modified or installed by the recipient, or for













the User Product in which it has been modified or installed.  Access to a













network may be denied when the modification itself materially and













adversely affects the operation of the network or violates the rules and













protocols for communication across the network.



























  Corresponding Source conveyed, and Installation Information provided,













in accord with this section must be in a format that is publicly













documented (and with an implementation available to the public in













source code form), and must require no special password or key for













unpacking, reading or copying.



























  7. Additional Terms.



























  "Additional permissions" are terms that supplement the terms of this













License by making exceptions from one or more of its conditions.













Additional permissions that are applicable to the entire Program shall













be treated as though they were included in this License, to the extent













that they are valid under applicable law.  If additional permissions













apply only to part of the Program, that part may be used separately













under those permissions, but the entire Program remains governed by













this License without regard to the additional permissions.



























  When you convey a copy of a covered work, you may at your option













remove any additional permissions from that copy, or from any part of













it.  (Additional permissions may be written to require their own













removal in certain cases when you modify the work.)  You may place













additional permissions on material, added by you to a covered work,













for which you have or can give appropriate copyright permission.



























  Notwithstanding any other provision of this License, for material you













add to a covered work, you may (if authorized by the copyright holders of













that material) supplement the terms of this License with terms:



























    a) Disclaiming warranty or limiting liability differently from the













    terms of sections 15 and 16 of this License; or



























    b) Requiring preservation of specified reasonable legal notices or













    author attributions in that material or in the Appropriate Legal













    Notices displayed by works containing it; or



























    c) Prohibiting misrepresentation of the origin of that material, or













    requiring that modified versions of such material be marked in













    reasonable ways as different from the original version; or



























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













    authors of the material; or



























    e) Declining to grant rights under trademark law for use of some













    trade names, trademarks, or service marks; or



























    f) Requiring indemnification of licensors and authors of that













    material by anyone who conveys the material (or modified versions of













    it) with contractual assumptions of liability to the recipient, for













    any liability that these contractual assumptions directly impose on













    those licensors and authors.



























  All other non-permissive additional terms are considered "further













restrictions" within the meaning of section 10.  If the Program as you













received it, or any part of it, contains a notice stating that it is













governed by this License along with a term that is a further













restriction, you may remove that term.  If a license document contains













a further restriction but permits relicensing or conveying under this













License, you may add to a covered work material governed by the terms













of that license document, provided that the further restriction does













not survive such relicensing or conveying.



























  If you add terms to a covered work in accord with this section, you













must place, in the relevant source files, a statement of the













additional terms that apply to those files, or a notice indicating













where to find the applicable terms.



























  Additional terms, permissive or non-permissive, may be stated in the













form of a separately written license, or stated as exceptions;













the above requirements apply either way.



























  8. Termination.



























  You may not propagate or modify a covered work except as expressly













provided under this License.  Any attempt otherwise to propagate or













modify it is void, and will automatically terminate your rights under













this License (including any patent licenses granted under the third













paragraph of section 11).



























  However, if you cease all violation of this License, then your













license from a particular copyright holder is reinstated (a)













provisionally, unless and until the copyright holder explicitly and













finally terminates your license, and (b) permanently, if the copyright













holder fails to notify you of the violation by some reasonable means













prior to 60 days after the cessation.



























  Moreover, your license from a particular copyright holder is













reinstated permanently if the copyright holder notifies you of the













violation by some reasonable means, this is the first time you have













received notice of violation of this License (for any work) from that













copyright holder, and you cure the violation prior to 30 days after













your receipt of the notice.



























  Termination of your rights under this section does not terminate the













licenses of parties who have received copies or rights from you under













this License.  If your rights have been terminated and not permanently













reinstated, you do not qualify to receive new licenses for the same













material under section 10.



























  9. Acceptance Not Required for Having Copies.



























  You are not required to accept this License in order to receive or













run a copy of the Program.  Ancillary propagation of a covered work













occurring solely as a consequence of using peer-to-peer transmission













to receive a copy likewise does not require acceptance.  However,













nothing other than this License grants you permission to propagate or













modify any covered work.  These actions infringe copyright if you do













not accept this License.  Therefore, by modifying or propagating a













covered work, you indicate your acceptance of this License to do so.



























  10. Automatic Licensing of Downstream Recipients.



























  Each time you convey a covered work, the recipient automatically













receives a license from the original licensors, to run, modify and













propagate that work, subject to this License.  You are not responsible













for enforcing compliance by third parties with this License.



























  An "entity transaction" is a transaction transferring control of an













organization, or substantially all assets of one, or subdividing an













organization, or merging organizations.  If propagation of a covered













work results from an entity transaction, each party to that













transaction who receives a copy of the work also receives whatever













licenses to the work the party's predecessor in interest had or could













give under the previous paragraph, plus a right to possession of the













Corresponding Source of the work from the predecessor in interest, if













the predecessor has it or can get it with reasonable efforts.



























  You may not impose any further restrictions on the exercise of the













rights granted or affirmed under this License.  For example, you may













not impose a license fee, royalty, or other charge for exercise of













rights granted under this License, and you may not initiate litigation













(including a cross-claim or counterclaim in a lawsuit) alleging that













any patent claim is infringed by making, using, selling, offering for













sale, or importing the Program or any portion of it.



























  11. Patents.



























  A "contributor" is a copyright holder who authorizes use under this













License of the Program or a work on which the Program is based.  The













work thus licensed is called the contributor's "contributor version".



























  A contributor's "essential patent claims" are all patent claims













owned or controlled by the contributor, whether already acquired or













hereafter acquired, that would be infringed by some manner, permitted













by this License, of making, using, or selling its contributor version,













but do not include claims that would be infringed only as a













consequence of further modification of the contributor version.  For













purposes of this definition, "control" includes the right to grant













patent sublicenses in a manner consistent with the requirements of













this License.



























  Each contributor grants you a non-exclusive, worldwide, royalty-free













patent license under the contributor's essential patent claims, to













make, use, sell, offer for sale, import and otherwise run, modify and













propagate the contents of its contributor version.



























  In the following three paragraphs, a "patent license" is any express













agreement or commitment, however denominated, not to enforce a patent













(such as an express permission to practice a patent or covenant not to













sue for patent infringement).  To "grant" such a patent license to a













party means to make such an agreement or commitment not to enforce a













patent against the party.



























  If you convey a covered work, knowingly relying on a patent license,













and the Corresponding Source of the work is not available for anyone













to copy, free of charge and under the terms of this License, through a













publicly available network server or other readily accessible means,













then you must either (1) cause the Corresponding Source to be so













available, or (2) arrange to deprive yourself of the benefit of the













patent license for this particular work, or (3) arrange, in a manner













consistent with the requirements of this License, to extend the patent













license to downstream recipients.  "Knowingly relying" means you have













actual knowledge that, but for the patent license, your conveying the













covered work in a country, or your recipient's use of the covered work













in a country, would infringe one or more identifiable patents in that













country that you have reason to believe are valid.



























  If, pursuant to or in connection with a single transaction or













arrangement, you convey, or propagate by procuring conveyance of, a













covered work, and grant a patent license to some of the parties













receiving the covered work authorizing them to use, propagate, modify













or convey a specific copy of the covered work, then the patent license













you grant is automatically extended to all recipients of the covered













work and works based on it.



























  A patent license is "discriminatory" if it does not include within













the scope of its coverage, prohibits the exercise of, or is













conditioned on the non-exercise of one or more of the rights that are













specifically granted under this License.  You may not convey a covered













work if you are a party to an arrangement with a third party that is













in the business of distributing software, under which you make payment













to the third party based on the extent of your activity of conveying













the work, and under which the third party grants, to any of the













parties who would receive the covered work from you, a discriminatory













patent license (a) in connection with copies of the covered work













conveyed by you (or copies made from those copies), or (b) primarily













for and in connection with specific products or compilations that













contain the covered work, unless you entered into that arrangement,













or that patent license was granted, prior to 28 March 2007.



























  Nothing in this License shall be construed as excluding or limiting













any implied license or other defenses to infringement that may













otherwise be available to you under applicable patent law.



























  12. No Surrender of Others' Freedom.



























  If conditions are imposed on you (whether by court order, agreement or













otherwise) that contradict the conditions of this License, they do not













excuse you from the conditions of this License.  If you cannot convey a













covered work so as to satisfy simultaneously your obligations under this













License and any other pertinent obligations, then as a consequence you may













not convey it at all.  For example, if you agree to terms that obligate you













to collect a royalty for further conveying from those to whom you convey













the Program, the only way you could satisfy both those terms and this













License would be to refrain entirely from conveying the Program.



























  13. Use with the GNU Affero General Public License.



























  Notwithstanding any other provision of this License, you have













permission to link or combine any covered work with a work licensed













under version 3 of the GNU Affero General Public License into a single













combined work, and to convey the resulting work.  The terms of this













License will continue to apply to the part which is the covered work,













but the special requirements of the GNU Affero General Public License,













section 13, concerning interaction through a network will apply to the













combination as such.



























  14. Revised Versions of this License.



























  The Free Software Foundation may publish revised and/or new versions of













the GNU General Public License from time to time.  Such new versions will













be similar in spirit to the present version, but may differ in detail to













address new problems or concerns.



























  Each version is given a distinguishing version number.  If the













Program specifies that a certain numbered version of the GNU General













Public License "or any later version" applies to it, you have the













option of following the terms and conditions either of that numbered













version or of any later version published by the Free Software













Foundation.  If the Program does not specify a version number of the













GNU General Public License, you may choose any version ever published













by the Free Software Foundation.



























  If the Program specifies that a proxy can decide which future













versions of the GNU General Public License can be used, that proxy's













public statement of acceptance of a version permanently authorizes you













to choose that version for the Program.



























  Later license versions may give you additional or different













permissions.  However, no additional obligations are imposed on any













author or copyright holder as a result of your choosing to follow a













later version.



























  15. Disclaimer of Warranty.



























  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY













APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT













HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY













OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,













THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR













PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM













IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF













ALL NECESSARY SERVICING, REPAIR OR CORRECTION.



























  16. Limitation of Liability.



























  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING













WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS













THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY













GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE













USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF













DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD













PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),













EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF













SUCH DAMAGES.



























  17. Interpretation of Sections 15 and 16.



























  If the disclaimer of warranty and limitation of liability provided













above cannot be given local legal effect according to their terms,













reviewing courts shall apply local law that most closely approximates













an absolute waiver of all civil liability in connection with the













Program, unless a warranty or assumption of liability accompanies a













copy of the Program in return for a fee.



























                     END OF TERMS AND CONDITIONS



























            How to Apply These Terms to Your New Programs



























  If you develop a new program, and you want it to be of the greatest













possible use to the public, the best way to achieve this is to make it













free software which everyone can redistribute and change under these terms.



























  To do so, attach the following notices to the program.  It is safest













to attach them to the start of each source file to most effectively













state the exclusion of warranty; and each file should have at least













the "copyright" line and a pointer to where the full notice is found.



























    <one line to give the program's name and a brief idea of what it does.>













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



























    This program is free software: you can redistribute it and/or modify













    it under the terms of the GNU General Public License as published by













    the Free Software Foundation, either version 3 of the License, or













    (at your option) any later version.



























    This program is distributed in the hope that it will be useful,













    but WITHOUT ANY WARRANTY; without even the implied warranty of













    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the













    GNU General Public License for more details.



























    You should have received a copy of the GNU General Public License













    along with this program.  If not, see <http://www.gnu.org/licenses/>.



























Also add information on how to contact you by electronic and paper mail.



























  If the program does terminal interaction, make it output a short













notice like this when it starts in an interactive mode:



























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













    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.













    This is free software, and you are welcome to redistribute it













    under certain conditions; type `show c' for details.



























The hypothetical commands `show w' and `show c' should show the appropriate













parts of the General Public License.  Of course, your program's commands













might be different; for a GUI interface, you would use an "about box".



























  You should also get your employer (if you work as a programmer) or school,













if any, to sign a "copyright disclaimer" for the program, if necessary.

  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
