<h1>The <u>T</u>erse <u>P</u>ublic <u>L</u>icense Family</h1>
<p>A family of minimal licenses for artists and developers, without
the sheer size of the more thorough licenses. If you forsee
yourself going to court, maybe pick something more robust. If you
just want something simple for a small project, this may well be
for you.</p>
<p>Feel free to <a href="https://amehut.dev/~aleteoryx/tpl">suggest
improvements</a>.</p>
