# palctl Contributor License Agreement

Thank you for contributing to palctl. This agreement sets out the
intellectual-property terms for contributions. Its purpose is narrow but
important: it lets palctl be offered **both** under the GNU AGPL-3.0 (the open
license everyone gets) **and**, where the AGPL doesn't fit, under separate
commercial licenses. That dual-licensing is only possible if the maintainer has
the right to relicense every contribution — which is what you grant below.

> **This is a template adapted from the Apache Software Foundation Individual
> CLA v2.0, with an added relicensing grant. It is not legal advice. Have a
> lawyer review it before relying on it for commercial licensing.**

By submitting a Contribution to palctl, you agree to the following for your past
and future Contributions.

## 1. Definitions

- **"You" / "Your"** — the individual or legal entity making a Contribution.
- **"Maintainer"** — _[insert the legal name or entity that holds palctl's
  copyright — e.g. "Steve Weed" or a company]_, the steward of palctl.
- **"Contribution"** — any original work of authorship, including any
  modification or addition, that You intentionally submit to the Maintainer for
  inclusion in palctl (via pull request, patch, or otherwise). "Submit" means any
  form of communication sent to the Maintainer or the project, except anything
  conspicuously marked "Not a Contribution."

## 2. Copyright license

You grant the Maintainer, and to recipients of software distributed by the
Maintainer, a perpetual, worldwide, non-exclusive, royalty-free, irrevocable
copyright license to reproduce, prepare derivative works of, publicly display,
publicly perform, sublicense, and distribute Your Contributions and such
derivative works.

You further grant the Maintainer the right to **license and relicense Your
Contribution under any terms, including copyleft (such as the GNU AGPL),
permissive, and proprietary or commercial licenses.** This is the specific
permission that allows palctl to be offered under the AGPL and, separately, under
commercial terms. You keep all right, title, and interest in Your Contribution —
this is a license, not an assignment of copyright.

## 3. Patent license

You grant the Maintainer, and recipients of palctl, a perpetual, worldwide,
non-exclusive, royalty-free, irrevocable (except as below) patent license to
make, have made, use, offer to sell, sell, import, and otherwise transfer palctl.
This license applies only to those patent claims licensable by You that are
necessarily infringed by Your Contribution alone or by the combination of Your
Contribution with palctl. If any entity brings patent litigation alleging that
palctl or a Contribution infringes a patent, any patent licenses granted under
this CLA for that work terminate as of the date the litigation is filed.

## 4. Your representations

You represent that:

1. You are legally entitled to grant the licenses above. If your employer has
   rights to intellectual property you create, you represent that you have
   permission to make the Contribution on your employer's behalf, that your
   employer has waived such rights, or that your employer has signed a separate
   corporate CLA with the Maintainer.
2. Each Contribution is Your original creation, or You have identified its source
   and any license or restriction covering any part that is not Your original
   creation (see Section 5).
3. To Your knowledge, Your Contribution does not violate any third party's
   copyright, trademark, patent, or other intellectual-property rights.

## 5. Third-party materials

If you want to submit work that is not your original creation, submit it
separately, clearly marking the source and any license or restriction, and label
it "Submitted on behalf of a third party: <name/license>".

## 6. Disclaimer

Unless required by applicable law or agreed in writing, You provide Your
Contributions on an "AS IS" basis, without warranties or conditions of any kind,
express or implied, including any warranty of merchantability, fitness for a
particular purpose, title, or non-infringement.

## 7. Notice

You agree to notify the Maintainer if any statement above becomes inaccurate.

## How to accept

See [CONTRIBUTING.md](CONTRIBUTING.md). In short: opening a pull request against

should carry a `Signed-off-by:` line (`git commit -s`).
