Apédice A: Licencia Pública General GNU¶

Versión 2, Junio de 1991

Se permite a cualquier persona la copia literal y distribución de este documento de licencia. Cobrar por estos conceptos no está permitido. This is an unofficial translation of the GNU Free Documentation License into Spanish. It was not published by the Free Software Foundation, and does not legally state the distribution terms for documentation that uses the GNU FDL – only the original English text of the GNU FDL does that. However, we hope that this translation will help Spanish speakers understand the GNU FDL better. Ésta es una traducción no oficial de la GNU Free Document License a Español (Castellano). No ha sido publicada por la Free Software Foundation y no establece legalmente los términos de distribución para trabajos que usen la GFDL (sólo el texto de la versión original en Inglés de la GFDL lo hace). Sin embargo, esperamos que esta traducción ayude a los hispanohablantes a entender mejor la GFDL. La versión original de la GFDL esta disponible en la Free Software Foundation. Esta traducción está basada en una de la versión 1.2 por Joaquín Seoane. Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. <http://www.fsf.org> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Se permite la copia y distribución de copias literales de este documento de licencia, pero no se permiten cambios.

Preámbulo

Las licencias para la mayoría del software están diseñadas para quitarle la libertad de compartirlo y cambiarlo. Por el contrario, the Licencia Pública General GNU pretende garantizar su libertad para compartir y cambiar el software libre – para asegurar que el software es libre para todos sus usuarios. La Licencia Pública General se aplica a la mayoría del software de la Fundación del Software Libre (Free Software Foundation) y para cualquier otro programa cuyos autores se comprometen a usarla. (Algún otro software de la Fundación del Software Libre está cubierto para la Licencia Pública General de Librería GNU (GNU Library General Public License) en su lugar.) Usted puede aplicarla a sus programas también.

Cuando hablamos de software libre, nos estamos refiriendo a la libertad no al precio. Nuestras Licencias Públicas Generales están diseñadas para asegurar que usted tiene la libertad de distribuir copias de software libre (y los cambios de este servicio que desee), que usted recibe el código fuente o puede obtenerlo si lo desea, que usted puede cambiar el software o usar parte de el para nuevos programas y que usted sabe que puede hacer estas cosas.

Para proteger sus derechos, necesitamos establecer restricciones que prohíban que nadie puede denegarle estos derecho o pedirle que renuncie a sus derechos. Estas restricciones se traducen en ciertas responsabilidades para usted si distribuye copias del software o lo modifica.

Por ejemplo, si usted distribuye copias de cualquier programa, ya sea gratis o por una tarifa, usted debe conceder a los receptores los mismos derechos de los que disfruta. Usted debe asegurarse de que ellos, también, reciben o pueden obtener el código fuente. Y usted debe mostrarles estos términos de modo que ellos conozcan sus derechos.

Protegemos sus derechos con dos pasos: (1) copyright del software, y (2) le ofrecemos esta licencia que le da permiso legal para copiar, distribuir y /o modificar el software.

Además, para la protección de cada autor y la nuestra, queremos asegurarnos de que todos entiendan que no hay garantía para este software libre. Si el software es modificado por cualquier y transmitido, deseamos que sus receptores sepan que lo que tienen no es original, de modo que cualquier problema introducido por otro no se refleje en la reputación de los autores.

Finalmente, cualquier programa libre está siempre amenazado por patentes de software. Deseamos evitar el peligro de que los redistribuidores de un programa libre obtengan individualmente licencias de patente, haciendo el programa propietario en efecto. Para evitar esto, hemos dejado claro que cualquier patente debe ser licenciada para el uso gratuito de cualquiera o no licenciada de ningún modo.

Los términos y condiciones para la copia, distribución y modificación siguen los TÉRMINOS Y CONDICIONES PARA LA COPIA, DISTRIBUCIÓN Y MODIFICACIÓN

Esta Licencia se aplica a cualquier programa u otro trabajo que contenga un aviso puesto por el poseedor del copyright diciendo que puede ser distribuido bajos los términos de esta Licencia Pública General. El «Programa», mas abajo, se refiere a cualquier programa o trabajo y un «trabajo basado en el Programa» significa el Programa o cualquier trabajo derivado bajo la ley de derechos de autor: es decir, un trabajo que contenga el Programa o una porción de él, ya sea textualmente o con modificaciones y/o traducido a cualquier otro idioma. (En adelante, la traducción se incluye sin limitaciones en el término «modificación».) A cada licenciatario se dirige como «usted».

Otras actividades distintas a la copia, distribución o modificación no están cubiertas por esta Licencia; están fuera de su alcance. El acto de ejecutar el Programa no está restringido y la salida del Programa está cubierta solo si sus contenidos constituyen un trabajo basado en el Programa (independiente de haber sido hecho ejecutando el Programa). Si eso es cierto depende de lo que haga el Programa.
Usted puede copiar y distribuir copias textuales del código fuente del Programa como lo recibe, en cualquier medio, siempre que se publique de forma conspicua y apropiada en cada copia un aviso de copyright apropiado y una exención de responsabilidad de garantía; mantenga intactos todos los avisos que se refieren a este Licencia y a la ausencia de cualquier garantía y le dé a cualquiera de los receptores del Programa una copia de esta Licencia junto con el Programa.

Puede cobrar una tarifa por el acto físico de transferir una copia y puede, a su elección, ofrecer protección de garantía a cambio de una tarifa.
Puede modificar su copia o copias del Programa o cualquier porción de él, formando así un trabajo basado en el Programa y copiar y distribuir esas modificaciones o trabajo bajo los términos de la Sección 1 de arriba, siempre que cumpla con todas estas condiciones:
1. Debe hacer que los archivos modificados lleven avisos de que usted ha cambiado los archivos y la fecha de cualquier cambio.
2. Debe causar que cualquier trabajo que distribuya o publique, que en todo o en parte contiene o se deriva del Programa o de cualquier parte del mismo, sea licenciado como un todo sin coste a todas los terceros bajo los términos de esta Licencia.
3. Si el programa modificado normalmente lee comandos interactivamente cuando se ejecuta, Debe causarlo, cuando empiece a ejecutar cualquier uso interactivo en el modo más ordinario, imprimiendo o mostrando un anuncio incluyendo un aviso de copyright apropiado y un aviso de que no hay garantía (si no, diciendo que usted suministra la garantía) y que los usuarios pueden redistribuir el programa bajo esas condiciones y decirle al usuario como puede ver una copia de esta Licencia. (Excepción: si el Programa mismo es interactivo y normalmente no imprime este anuncio, su trabajo basado en el Programa no requiere que imprima el anuncio.)
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.
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.
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.
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.
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.
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.
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.
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.
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.

NO WARRANTY

BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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.

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-commercial 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.
