violations are on works under GPLv2.</li>

</ul>

<p>These principles are not intended as a strict set of rules.

Achieving compliance requires an understanding of the violator's

situation, not so as to excuse the violation, but so as to see how

to bring that violator into compliance.  Copyleft licenses do not

state specific enforcement methodologies (other than license termination itself)

in part because the real world situation of GPL violations varies;

rigidity impedes success. </p>

<p>In particular, this list of principles purposely does not seek to

create strict criteria and/or “escalation and mediation

rules” for enforcement action. Efforts to do that limit the

ability of copyright holders to use copyleft licenses for their

intended effect: to stand up for the rights of users to copy, modify,

and redistribute free software.</p>

<p>The GPL,

enforced when necessary according to these principles, provides a

foundation for respectful, egalitarian, software-sharing

communities.
