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. + + + Copyright (C) + + 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 . + +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: + + Copyright (C) + 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/](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.
