+SPDX-URL: https://spdx.org/licenses/copyleft-next-0.3.1
+Usage-Guide:
+ copyleft-next-0.3.1 is explicitly compatible with GPLv2 (or later) and
+ can therefore be used for kernel code. Though the best and recommended
+ practice is to express this in the SPDX license identifier by
+ licensing the code under both licenses expressed by the OR operator.
+ To use the copyleft-next-0.3.1 license put the following SPDX tag/value
+ pair into a comment according to the placement guidelines in the
+ licensing rules documentation:
+ SPDX-License-Identifier: GPL-2.0-only OR copyleft-next 0.3.1
+ SPDX-License-Identifier: GPL-2.0-or-later OR copyleft-next-0.3.1
+License-Text:

+=======================================================================
+
+ copyleft-next 0.3.1 ("this License")
+ Release date: 2016-04-29
+
+1. License Grants; No Trademark License
+
+ Subject to the terms of this License, I grant You:
+
+ a) A non-exclusive, worldwide, perpetual, royalty-free, irrevocable
+ copyright license, to reproduce, Distribute, prepare derivative works
+ of, publicly perform and publicly display My Work.
+
+ b) A non-exclusive, worldwide, perpetual, royalty-free, irrevocable
+ patent license under Licensed Patents to make, have made, use, sell,
+ offer for sale, and import Covered Works.
+
+ This License does not grant any rights in My name, trademarks, service
+ marks, or logos.
+
+2. Distribution: General Conditions
+
+ You may Distribute Covered Works, provided that You (i) inform
+ recipients how they can obtain a copy of this License; (ii) satisfy the
+ applicable conditions of sections 3 through 6; and (iii) preserve all
+ Legal Notices contained in My Work (to the extent they remain
+ pertinent). "Legal Notices" means copyright notices, license notices,
+ license texts, and author attributions, but does not include logos,
+ other graphical images, trademarks or trademark legends.
+
+3. Conditions for Distributing Derived Works; Outbound GPL Compatibility
+
+ If You Distribute a Derived Work, You must license the entire Derived
+ Work as a whole under this License, with prominent notice of such
+ licensing. This condition may not be avoided through such means as
+ separate Distribution of portions of the Derived Work.
+
+ If the Derived Work includes material licensed under the GPL, You may
+ instead license the Derived Work under the GPL.
+
+4. Condition Against Further Restrictions; Inbound License Compatibility
+
+ When Distributing a Covered Work, You may not impose further
+ restrictions on the exercise of rights in the Covered Work granted under
+ this License. This condition is not excused merely because such
+ restrictions result from Your compliance with conditions or obligations
+ extrinsic to this License (such as a court order or an agreement with a
+ third party).
+
+ However, You may Distribute a Covered Work incorporating material
+ governed by a license that is both OSI-Approved and FSF-Free as of the
+ release date of this License, provided that compliance with such
+ other license would not conflict with any conditions stated in other
+ sections of this License.
+
+5. Conditions for Distributing Object Code
+
+ You may Distribute an Object Code form of a Covered Work, provided that
+ you accompany the Object Code with a URL through which the Corresponding
+ Source is made available, at no charge, by some standard or customary
+ means of providing network access to source code.
+
+ If you Distribute the Object Code in a physical product or tangible
+ storage medium ("Product"), the Corresponding Source must be available
+ through such URL for two years from the date of Your most recent
+ Distribution of the Object Code in the Product. However, if the Product
+ itself contains or is accompanied by the Corresponding Source (made
+ available in a customarily accessible manner), You need not also comply
+ with the first paragraph of this section.
+
+ Each direct and indirect recipient of the Covered Work from You is an
+ intended third-party beneficiary of this License solely as to this
+ section 5, with the right to enforce its terms.
+
+6. Symmetrical Licensing Condition for Upstream Contributions
+
+ If You Distribute a work to Me specifically for inclusion in or
+ modification of a Covered Work (a "Patch"), and no explicit licensing
+ terms apply to the Patch, You license the Patch under this License, to
+ the extent of Your copyright in the Patch. This condition does not
+ negate the other conditions of this License, if applicable to the Patch.
+
+7. Nullification of Copyleft/Proprietary Dual Licensing
+
+ If I offer to license, for a fee, a Covered Work under terms other than
+ a license that is OSI-Approved or FSF-Free as of the release date of this
+ License or a numbered version of copyleft-next released by the
+ Copyleft-Next Project, then the license I grant You under section 1 is no
+ longer subject to the conditions in sections 3 through 5.
+
+8. Copyleft Sunset
+
+ The conditions in sections 3 through 5 no longer apply once fifteen
+ years have elapsed from the date of My first Distribution of My Work
+ under this License.
+
+9. Pass-Through
+
+ When You Distribute a Covered Work, the recipient automatically receives
+ a license to My Work from Me, subject to the terms of this License.
+
+10. Termination
+
+ Your license grants under section 1 are automatically terminated if You
+
+ a) fail to comply with the conditions of this License, unless You cure
+ such noncompliance within thirty days after becoming aware of it, or
+
+ b) initiate a patent infringement litigation claim (excluding
+ declaratory judgment actions, counterclaims, and cross-claims)
+ alleging that any part of My Work directly or indirectly infringes
+ any patent.
+
+ Termination of Your license grants extends to all copies of Covered
+ Works You subsequently obtain. Termination does not terminate the
+ rights of those who have received copies or rights from You subject to
+ this License.
+
+ To the extent permission to make copies of a Covered Work is necessary
+ merely for running it, such permission is not terminable.
+
+11. Later License Versions
+
+ The Copyleft-Next Project may release new versions of copyleft-next,
+ designated by a distinguishing version number ("Later Versions").
+ Unless I explicitly remove the option of Distributing Covered Works
+ under Later Versions, You may Distribute Covered Works under any Later
+ Version.
+
+** 12. No Warranty **
+** **
+** My Work is provided "as-is", without warranty. You bear the risk **
+** of using it. To the extent permitted by applicable law, each **
+** Distributor of My Work excludes the implied warranties of title, **
+** merchantability, fitness for a particular purpose and **
+** non-infringement. **
+
+** 13. Limitation of Liability **
+** **
+** To the extent permitted by applicable law, in no event will any **
+** Distributor of My Work be liable to You for any damages **
+** whatsoever, whether direct, indirect, special, incidental, or **
+** consequential damages, whether arising under contract, tort **
+** (including negligence), or otherwise, even where the Distributor **
+** knew or should have known about the possibility of such damages. **
+
+14. Severability
+
+ The invalidity or unenforceability of any provision of this License
+ does not affect the validity or enforceability of the remainder of
+ this License. Such provision is to be reformed to the minimum extent
+ necessary to make it valid and enforceable.
+
+15. Definitions
+
+ "Copyleft-Next Project" means the project that maintains the source
+ code repository at
+ as of the release date of this License.
+
+ "Corresponding Source" of a Covered Work in Object Code form means (i)
+ the Source Code form of the Covered Work; (ii) all scripts,
+ instructions and similar information that are reasonably necessary for
+ a skilled developer to generate such Object Code from the Source Code
+ provided under (i); and (iii) a list clearly identifying all Separate
+ Works (other than those provided in compliance with (ii)) that were
+ specifically used in building and (if applicable) installing the
+ Covered Work (for example, a specified proprietary compiler including
+ its version number). Corresponding Source must be machine-readable.
+
+ "Covered Work" means My Work or a Derived Work.
+
+ "Derived Work" means a work of authorship that copies from, modifies,
+ adapts, is based on, is a derivative work of, transforms, translates or
+ contains all or part of My Work, such that copyright permission is
+ required. The following are not Derived Works: (i) Mere Aggregation;
+ (ii) a mere reproduction of My Work; and (iii) if My Work fails to
+ explicitly state an expectation otherwise, a work that merely makes
+ reference to My Work.
+
+ "Distribute" means to distribute, transfer or make a copy available to
+ someone else, such that copyright permission is required.
+
+ "Distributor" means Me and anyone else who Distributes a Covered Work.
+
+ "FSF-Free" means classified as 'free' by the Free Software Foundation.
+
+ "GPL" means a version of the GNU General Public License or the GNU
+ Affero General Public License.
+
+ "I"/"Me"/"My" refers to the individual or legal entity that places My
+ Work under this License. "You"/"Your" refers to the individual or legal
+ entity exercising rights in My Work under this License. A legal entity
+ includes each entity that controls, is controlled by, or is under
+ common control with such legal entity. "Control" means (a) the power to
+ direct the actions of such legal entity, whether by contract or
+ otherwise, or (b) ownership of more than fifty percent of the
+ outstanding shares or beneficial ownership of such legal entity.
+
+ "Licensed Patents" means all patent claims licensable royalty-free by
+ Me, now or in the future, that are necessarily infringed by making,
+ using, or selling My Work, and excludes claims that would be infringed
+ only as a consequence of further modification of My Work.
+
+ "Mere Aggregation" means an aggregation of a Covered Work with a
+ Separate Work.
+
+ "My Work" means the particular work of authorship I license to You
+ under this License.
+
+ "Object Code" means any form of a work that is not Source Code.
+
+ "OSI-Approved" means approved as 'Open Source' by the Open Source
+ Initiative.
+
+ "Separate Work" means a work that is separate from and independent of a
+ particular Covered Work and is not by its nature an extension or
+ enhancement of the Covered Work, and/or a runtime library, standard
+ library or similar component that is used to generate an Object Code
+ form of a Covered Work.
+
+ "Source Code" means the preferred form of a work for making
+ modifications to it.
