Version 1.0
Thank you for your interest in contributing to phpcpd-next (the "Project"), maintained by Luciano Federico Pereira (the "Project Owner").
This Contributor License Agreement ("Agreement") documents the rights granted by contributors to the Project Owner. It exists so the Project can be distributed under permissive terms today while keeping the option to relicense or dual-license in the future — which requires the Project Owner to hold a clear, broad license to every contribution. By submitting a Contribution to the Project, You accept and agree to the following terms for Your present and future Contributions.
This document is a template adapted from the Apache Software Foundation Individual CLA. It is provided for convenience and is not legal advice. Before relying on it for relicensing, dual-licensing, or any commercial purpose, have it reviewed by a lawyer in the relevant jurisdiction.
"You" (or "Your") means the individual who submits a Contribution to the Project, or the legal entity authorised by that individual. For legal entities, the entity making a Contribution and all other entities that control, are controlled by, or are under common control with that entity are considered a single Contributor.
"Contribution" means any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to the Project for inclusion in, or documentation of, any of the products owned or managed by the Project (the "Work"). "Submitted" means any form of electronic, verbal, or written communication sent to the Project or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, the Project — excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."
Subject to the terms and conditions of this Agreement, You hereby grant to the Project Owner and to recipients of software distributed by the Project a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works.
Subject to the terms and conditions of this Agreement, You hereby grant to the Project Owner and to recipients of software distributed by the Project a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution alone or by combination of Your Contribution with the Work to which such Contribution was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that Your Contribution, or the Work to which You have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
You acknowledge and agree that the Project Owner may license and sublicense Your Contribution, and any derivative works thereof, under any license terms the Project Owner chooses, including permissive open-source licenses (such as the BSD 3-Clause License under which the Project is currently distributed), other open-source licenses, and proprietary or commercial license terms. This Section 4 preserves the Project Owner's ability to relicense or dual-license the Project as a whole in the future. Nothing in this Agreement requires the Project Owner to exercise this right, and the Project's then-current public license remains available to all recipients on its stated terms.
You retain all right, title, and interest in and to Your Contributions. This Agreement is a license, not an assignment of copyright; You are free to use Your Contributions for any other purpose.
You represent that:
-
You are legally entitled to grant the above licenses. If Your employer(s) have rights to intellectual property that You create that includes Your Contributions, You represent that You have received permission to make Contributions on behalf of that employer, that Your employer has waived such rights for Your Contributions to the Project, or that Your employer has executed a separate Corporate CLA with the Project Owner.
-
Each of Your Contributions is Your original creation (see Section 6 for submissions on behalf of others).
-
Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which You are personally aware and which are associated with any part of Your Contributions.
Should You wish to submit work that is not Your original creation, You may submit it to the Project separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which You are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
You agree to notify the Project Owner of any facts or circumstances of which You become aware that would make these representations inaccurate in any respect.
