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. 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>>. |
