Scope of the MIT license
========================

The MIT license in LICENSE applies to the software in this repository: the
source code, the tests and the documentation.

It does not grant any rights to the song lyrics quoted here. Short lyric
fragments appear in the test fixtures as sample input. They are the
copyrighted work of their author (屠龍 / TORYU), reproduced as test data only.
Reusing them is not covered by LICENSE.

The exception is examples/amazing_grace.txt. "Amazing Grace" is a public-domain
hymn, and the recording the README points at is a public-domain work of the
United States Air Force Reserve Band. That is why the README walkthrough uses
it: anyone can reproduce that run end to end.
