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. + +ÒThis LicenseÓ refers to version 3 of the GNU General Public License. + +ÒCopyrightÓ also means copyright-like laws that apply to other kinds of works, such as +semiconductor masks. + +ÒThe ProgramÓ refers to any copyrightable work licensed under this License. Each licensee +is addressed as ÒyouÓ. ÒLicenseesÓ and ÒrecipientsÓ may be individuals or organizations. + +To ÒmodifyÓ 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 Òmodified versionÓ of the earlier work or a work Òbased onÓ the earlier +work. + +A Òcovered workÓ means either the unmodified Program or a work based on the Program. + +To ÒpropagateÓ 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 ÒconveyÓ 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 ÒAppropriate Legal NoticesÓ 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 Òsource codeÓ for a work means the preferred form of the work for making modifications to it. +ÒObject codeÓ means any non-source form of a work. + +A ÒStandard InterfaceÓ 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 ÒSystem LibrariesÓ 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 ÒMajor ComponentÓ, 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 ÒCorresponding SourceÓ 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 Òkeep intact all noticesÓ. + * 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 ÒaggregateÓ 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 ÒUser ProductÓ is either (1) a Òconsumer productÓ, 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, Ònormally usedÓ 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. + +ÒInstallation InformationÓ 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. + +ÒAdditional permissionsÓ 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 Òfurther restrictionsÓ 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 Òentity transactionÓ 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 ÒcontributorÓ 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 +Òcontributor versionÓ. + +A contributor's Òessential patent claimsÓ 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, ÒcontrolÓ 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 Òpatent licenseÓ 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 ÒgrantÓ 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. ÒKnowingly relyingÓ 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 ÒdiscriminatoryÓ 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 Òor any later versionÓ 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 +ÒAS ISÓ 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 ÒcopyrightÓ 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 Òabout boxÓ. + +You should also get your employer (if you work as a programmer) or school, if any, to sign +a Òcopyright disclaimerÓ for the program, if necessary. For more information on this, and +how to apply and follow the GNU GPL, see <http://www.gnu.org/licenses/>. + +The GNU General Public License does not permit incorporating your program into proprietary +programs. If your program is a subroutine library, you may consider it more useful to permit +linking proprietary applications with the library. If this is what you want to do, use the +GNU Lesser General Public License instead of this License. But first, please read +<http://www.gnu.org/philosophy/why-not-lgpl.html>. |
