Licensing

This library is free to use under AGPL-3.0-or-later, and always will be. No registration, no key, no gate.

Every use falls under AGPL-3.0-or-later unless you hold explicit permission, which is one of exactly two things:

• A commercial contract, negotiated and signed. Where the AGPL's terms do not suit a product, terms are negotiable. Write to dquigg123@gmail.com. See LICENSES/LicenseRef-Commercial.txt.

• An educator's license, issued to you personally. Write from your faculty, research or teaching address, ordinarily .edu or .org, describing what you intend to do with it. Granted case by case. See LICENSES/LicenseRef-Educational.txt.

The educator's license exists so that value returns to your institution and your department, and the environment that produced the work is enriched by what the work becomes. That is its whole purpose, and it is a term of the license. Credit the underlying systems and the students and faculty who did the work, and if the work becomes a product, a royalty ladder applies with a share to the institution at minimum and to the department where its rules allow (LICENSES/LicenseRef-Educational.txt:71, :137-150).

It is issued to a person, and it does not extend to a colleague, a student, a collaborator, a department, a laboratory or an institution (LICENSES/LicenseRef-Educational.txt:34, :76). Each person applies for their own, there is no grandfathering, and it is revocable at will. Conduct undertaken to defeat its purpose ends it immediately, with no notice period and no opportunity to cure (LICENSES/LicenseRef-Educational.txt:81, :170-179).

If you do not intend to return value to your institution, take the AGPL. It costs nothing and asks none of this.
