Contributing

When this license requires you to contribute:

  1. Publish all source code, in the preferred form for making changes, through a freely accessible distribution system widely used for similar source code, so the contributor and others can find and copy it.

  2. Ensure that each part of that source code is available to the public under a license at least as permissive as this one, such as MIT, two-clause BSD license, Apache 2.0, or Blue Oak Model 1.0.0.

  3. Take these steps within thirty calendar days of when you first did anything triggering a rule requiring contribution.

  4. Note that this license does not allow you to change the license terms for this software.

Patent

The contributor licenses you to do everything with this software that would otherwise infringe any patent claims they can license or become able to license.

Excuse

You are excused for unknowingly breaking copyleft if you contribute as required, or stop doing anything requiring this license, within thirty days of learning you broke that rule. You are excused for unknowingly breaking notices if you take all practical steps to comply within thirty days of learning you broke that rule.
