Se permite a todos copiar y distribuir copias exactas de este documento de licencia, aunque no se permite su cambio.


The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software–to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation’s software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

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

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

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

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author’s protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors’ reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone’s free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  1. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The “Program”, below, refers to any such program or work, and a “work based on the Program” means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term “modification”.) Each licensee is addressed as “you”.

    Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

  2. You may copy and distribute verbatim copies of the Program’s source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

    You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

  3. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

    1. You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
    2. You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
    3. If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

    These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

    Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

    In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

  4. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

    1. Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
    2. Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
    3. Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

    The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

    If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

  5. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

  6. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

  7. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients’ exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

  8. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

    If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

    It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

    This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

  9. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

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

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

  11. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.



QGIS Qt excepciones para GPL

In addition, as a special exception, the QGIS Development Team gives permission to link the code of this program with the Qt library, including but not limited to the following versions (both free and commercial): Qt/Non-commerical Windows, Qt/Windows, Qt/X11, Qt/Mac, and Qt/Embedded (or with modified versions of Qt that use the same license as Qt), and distribute linked combinations including the two. You must obey the GNU General Public License in all respects for all of the code used other than Qt. If you modify this file, you may extend this exception to your version of the file, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.

Licencia de Documentación Libre de GNU

Versión 1.3, 3 de Noviembre de 2008

Derechos Reservados 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc


Se permite a todos copiar y distribuir copias exactas de este documento de licencia, aunque no se permite su cambio.


El propósito de esta Licencia es permitir que un manual, libro de texto, u otro documento escrito sea “libre” en el sentido de libertad: asegurar a todo el mundo la libertad efectiva de copiarlo y redistribuirlo, con o sin odificaciones, de manera comercial o no. En segundo término, esta Licencia proporciona al autor y al editor una manera de obtener reconocimiento por su trabajo, sin que se le considere responsable de las modificaciones realizadas por otros.

Esta Licencia es de tipo “copyleft”, lo que significa que los trabajos derivados del documento deben a su vez ser libres en el mismo sentido. Complementa la Licencia Pública General de GNU, que es una licencia tipo copyleft diseñada para el software libre.

We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.


Esta Licencia se aplica a cualquier manual u otro trabajo, en cualquier soporte, que contenga una nota del propietario de los derechos de autor que indique que puede ser distribuido bajo los términos de esta Licencia. Tal nota garantiza en cualquier lugar del mundo, sin pago de derechos y sin límite de tiempo, el uso de dicho trabajo según las condiciones aquí estipuladas. En adelante la palabra Documento se referirá a cualquiera de dichos manuales o trabajos. Cualquier persona es un licenciatario y será referido como “Usted”. Usted acepta la licencia si copia. modifica o distribuye el trabajo de cualquier modo que requiera permiso según la ley de propiedad intelectual.

A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

Una “Sección Secundaria” es un apéndice con título o una sección preliminar del Documento que trata exclusivamente de la relación entre los autores o editores y el tema general del Documento (o temas relacionados) pero que no contiene nada que entre directamente en dicho tema general (por ejemplo, si el Documento es en parte un texto de matemáticas, una Sección Secundaria puede no explicar nada de matemáticas). La relación puede ser una conexión histórica con el tema o temas relacionados, o una opinión legal, comercial, filosófica, ética o política acerca de ellos.

The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

Los “Textos de Cubierta” son ciertos pasajes cortos de texto que se listan como Textos de Cubierta Delantera o Textos de Cubierta Trasera en la nota que indica que el documento es liberado bajo esta Licencia. Un Texto de Cubierta delantera puede tener como mucho 5 palabras, y uno de Cubierta Trasera puede tener hasta 25 palabras.

A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called Opaque.

Como ejemplos de formatos adecuados para copias Transparentes están ASCII puro sin marcaje, formato de entrada de Texinfo, formato de entrada de LaTeX, SGML o XML usando una DTD disponible públicamente, y HTML, PostScript o PDF simples, que sigan los estándares y diseñados para que los modifiquen personas. Ejemplos de formatos de imagen transparentes son PNG, XCF y JPG. Los formatos Opacos incluyen formatos propietarios que pueden ser leídos y editados únicamente en procesadores de palabras propietarios, SGML o XML para los cuáles las DTD y/o herramientas de procesamiento no estén ampliamente disponibles, y HTML, PostScript o PDF generados por algunos procesadores de palabras sólo como salida.

La “Portada” significa, en un libro impreso, la página de título, más las páginas siguientes que sean necesarias para mantener legiblemente el material que esta Licencia requiere en la portada. Para trabajos en formatos que no tienen página de portada como tal, Portada significa el texto cercano a la aparición más prominente del título del trabajo, precediendo el comienzo del cuerpo del texto.

El “Editor” se refiere a cualquier persona o entidad que distribuya copias del Documento a el público.

Una sección “Titulada XYZ” significa una parte del Documento cuyo título es precisamente XYZ o contiene XYZ entre paréntesis, a continuación de texto que traduce XYZ a otro idioma (aquí XYZ se refiere a nombres de sección específicos mencionados más abajo, como “Agradecimientos”, “Dedicatorias”, “Aprobaciones” o “Historia”). “Conservar el Título” de tal sección cuando se modifica el Documento significa que permanece una sección “Titulada XYZ” según esta definición.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.


You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

Usted también puede prestar copias, bajo las mismas condiciones establecidas anteriormente, y puede exhibir copias públicamente.


If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

Si los textos requeridos para la cubierta son muy voluminosos para que ajusten legiblemente, debe colocar los primeros (tantos como sea razonable colocar) en la verdadera cubierta y situar el resto en páginas adyacentes.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.


Puede copiar y distribuir una Versión Modificada del Documento bajo las condiciones de las secciones 2 y 3 anteriores, siempre que usted libere la Versión Modificada bajo esta misma Licencia, con la Versión Modificada haciendo el rol del Documento, por lo tanto dando licencia de distribución y modificación de la Versión Modificada a quienquiera posea una copia de la misma. Además, debe hacer lo siguiente en la Versión Modificada:

  1. Usar en la Portada (y en las cubiertas, si hay alguna) un título distinto al del Documento y de sus versiones anteriores (que deberían, si hay alguna, estar listadas en la sección de Historia del Documento). Puede usar el mismo título de versiones anteriores al original siempre y cuando quien las publicó originalmente otorgue permiso.

  2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
  3. Mostrar en la Portada como editor el nombre del editor de la Versión Modificada.

  4. Preservar todas las notas de derechos de autor del Documento.

  5. Agregue una nota de derechos reservados apropiada para sus modificaciones adyacente a las otras notas de derechos reservados.

  6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
  7. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
  8. Incluir una copia sin modificación de esta Licencia.

  9. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
  10. Conservar la dirección en red, si la hay, dada en el Documento para el acceso público a una copia transparente del mismo, así como las otras direcciones de red dadas en el Documento para versiones anteriores en las que estuviese basado. Pueden ubicarse en la sección “Historia”. Se puede omitir la ubicación en red de un trabajo que haya sido publicado por lo menos cuatro años antes que el Documento mismo, o si el editor original de dicha versión da permiso.

  11. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
  12. Conservar todas las Secciones Invariantes del Documento, sin alterar su texto ni sus títulos. Números de sección o el equivalente no son considerados parte de los títulos de la sección.

  13. Borrar cualquier sección titulada Aprobaciones. Tales secciones no pueden estar incluidas en las Versiones Modificadas.

  14. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section.
  15. Conservar todas las Limitaciones de Garantía.

Si la Versión Modificada incluye secciones o apéndices nuevos que califiquen como Secciones Secundarias y contienen material no copiado del Documento, puede opcionalmente designar algunas o todas esas secciones como invariantes. Para hacerlo, añada sus títulos a la lista de Secciones Invariantes en la nota de licencia de la Versión Modificada. Tales títulos deben ser distintos de cualquier otro título de sección.

You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

Puede añadir un pasaje de hasta cinco palabras como Texto de Cubierta Delantera y un pasaje de hasta 25 palabras como Texto de Cubierta Trasera en la Versión Modificada. Una entidad solo puede añadir (o hacer que se añada) un pasaje al Texto de Cubierta Delantera y uno al de Cubierta Trasera. Si el Documento ya incluye un textos de cubiertas añadidos previamente por usted o por la misma entidad que usted representa, usted no puede añadir otro; pero puede reemplazar el anterior, con permiso explícito del editor que agregó el texto anterior.

Con esta Licencia ni el/los autor(es) ni el/los editor(es) del Documento dan permiso para usar sus nombres para publicidad ni para asegurar o implicar aprobación de cualquier Versión Modificada.


Usted puede combinar el Documento con otros documentos liberados bajo esta Licencia, bajo los términos definidos en la sección 4 anterior para versiones modificadas, siempre que incluya en la combinación todas las Secciones Invariantes de todos los documentos originales, sin modificar, listadas todas como Secciones Invariantes del trabajo combinado en su nota de licencia. Así mismo debe incluir la Limitación de Garantía.

El trabajo combinado necesita contener solamente una copia de esta Licencia, y puede reemplazar varias Secciones Invariantes idénticas por una sola copia. Si hay varias Secciones Invariantes con el mismo nombre pero con contenidos diferentes, haga el título de cada una de estas secciones único añadiéndole al final del mismo, entre paréntesis, el nombre del autor o editor original de esa sección, si es conocido, o si no, un número único. Haga el mismo ajuste a los títulos de sección en la lista de Secciones Invariantes de la nota de licencia del trabajo combinado.

En la combinación, debe combinar cualquier sección Titulada “Historia” de los documentos originales, formando una sección Titulada “Historia”; de la misma forma combine cualquier sección Titulada “Agradecimientos”, y cualquier sección Titulada “Dedicatorias”. Debe borrar todas las secciones tituladas “Aprobaciones”.


You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

Puede extraer un solo documento de una de tales colecciones y distribuirlo individualmente bajo esta Licencia, siempre que inserte una copia de esta Licencia en el documento extraído, y siga esta Licencia en todos los demás aspectos relativos a la copia literal de dicho documento.


Una recopilación que conste del Documento o sus derivados y de otros documentos o trabajos separados e independientes, en cualquier soporte de almacenamiento o distribución, se denomina un “agregado” si el copyright resultante de la compilación no se usa para limitar los derechos de los usuarios de la misma más allá de lo que los de los trabajos individuales permiten. Cuando el Documento se incluye en un agregado, esta Licencia no se aplica a otros trabajos del agregado que no sean en sí mismos derivados del Documento.

Si el requisito de la sección 3 sobre el Texto de Cubierta es aplicable a estas copias del Documento y el Documento es menor que la mitad del agregado entero, los Textos de Cubierta del Documento pueden colocarse en cubiertas que enmarquen solamente el Documento dentro del agregado, o el equivalente electrónico de las cubiertas si el documento está en forma electrónica. En caso contrario deben aparecer en cubiertas impresas enmarcando todo el agregado.


La Traducción es considerada como un tipo de modificación, por lo que usted puede distribuir traducciones del Documento bajo los términos de la sección 4. El reemplazo las Secciones Invariantes con traducciones requiere permiso especial de los dueños de derecho de autor, pero usted puede añadir traducciones de algunas o todas las Secciones Invariantes a las versiones originales de las mismas. Puede incluir una traducción de esta Licencia, de todas las notas de licencia del documento, así como de las Limitaciones de Garantía, siempre que incluya también la versión en Inglés de esta Licencia y las versiones originales de las notas de licencia y Limitaciones de Garantía. En caso de desacuerdo entre la traducción y la versión original en Inglés de esta Licencia, la nota de licencia o la limitación de garantía, la versión original en Inglés prevalecerá.

Si una sección del Documento está Titulada “Agradecimientos”, “Dedicatorias” o “Historia” el requisito (sección 4) de Conservar su Título (Sección 1) requerirá, típicamente, cambiar su título.


Usted no puede copiar, modificar, sublicenciar o distribuir el Documento salvo por lo permitido expresamente bajo esta Licencia. Cualquier intento en otra manera de copia, modificación, sublicenciamiento, o distribución de él es nulo, y dará por terminados automáticamente sus derechos bajo esa Licencia.

Sin embargo, si usted cesa toda violación a esta Licencia, entonces su licenca proveniente de un titular de copyright queda restaurada (a) provisionalmente, a menos y hasta que el titular del copyright explicita y finalmente termine su licencia, y (b) permanentemente, si el titual del copyright falla en notificarle de la violación por algún medio razonable en un tiempo menor a 60 días después del cese.

Además, su licencia proveniente de un titular del copyright particular queda restaurada permanentemente si el titular del copyright lo notifica de la violación por algún método razonable, es la primera vez que usted ha recibido aviso de la violación de esta Licencia (para cualquier trabajo) de ese titular del copyright, y usted remedia la violación en un tiempo menor a 30 días después de recibir dicho aviso.

La terminación de sus derechos bajo ésta sección no termina la licenica de terceros que hayan recibido copias o derechos de usted bajo ésta Licencia. Si sus derechos han sido terminados y no restaurados permanentemente, recibir una copia de alguna parte o el total del mismo material no le da ningún derecho de usarlo.


The Free Software Foundation may publish new, revised versions of the GNU Free Documentation 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. See http://www.gnu.org/copyleft/.

Cada versión de la Licencia tiene un número de versión que la distingue. Si el Documento especifica que se aplica una versión numerada en particular de esta licencia “o cualquier versión posterior”, usted tiene la opción de seguir los términos y condiciones de la versión especificada o cualquiera posterior que haya sido publicada (no como borrador) por la Free Software Foundation. Si el Documento no especifica un número de versión de esta Licencia, puede escoger cualquier versión que haya sido publicada (no como borrador) por la Free Software Foundation. Si el Documento especifica que un apoderado puede decidir qué versión futura de esta Licencia puede ser utilizada, esa frase de aceptación del apoderado de una versión le autoriza permanentemente a escoger esa versión para el Documento.


“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.

“CC-BY-SA” significa la licencia Creative Commons Attribution-Share Alike 3.0 (Reconocimiento-Compartir bajo la misma licencia 3.0 de Creative Commons) publicada por Creative Commons Corporation, una corporación sin fines de lucro con base en San Francisco, California, así como versiones futuras copyleft de esa licencia publicada por esa misma organización.

“Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document.

Un sitio CMM es “elegible para re-licenciamiento” si es licenciado bajo esta Licencia, y si todos los trabajos que fueron publicados originalmente bajo esta Licencia en algún otro lugar diferente a esta CMM, y subsecuentemente incorporado como un todo o parcialmente a la CMM, (1)no tenía textos de cubierta o secciones invariantes, y (2) fueron incorporados previo a Noviembre 1, 2008.

The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.

APÉNDICE: Cómo usar esta Licencia para sus documentos

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Copyright © YEAR  YOUR NAME.
Permission is granted to copy, distribute and/or modify this document
under the terms of the GNU Free Documentation License, Version 1.3
or any later version published by the Free Software Foundation;
with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
A copy of the license is included in the section entitled "GNU
Free Documentation License".

Si tiene Secciones Invariantes, Textos de Cubierta Delantera y Textos de Cubierta Trasera, reemplace la frase “sin ... Trasera” por esto:

with the Invariant Sections being LIST THEIR TITLES, with the
Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
