Families

Permissive: Licences in this family ask little more than that the copyright notice and the licence text stay with copies.
Weak copyleft: Licences in this family ask that changed versions of the licensed code itself stay under the same licence, but not the other code it is combined with.
Copyleft: Licences in this family ask that works based on the licensed code carry the same licence when they are distributed, and the GPL asks for their source code as well.
Terms in a file: The terms are only in the package's own licence file.

offers no permissive licence, in a family that raises the flag
