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 <https://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 <https://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 <https://www.gnu.org/licenses/why-not-lgpl.html>.
