senku attribution notice
=========================

senku is an independent, from-scratch implementation. No source code was
copied from any third-party project; every module in this repository was
written by reading publicly available documentation and reference material
describing the target algorithms, then re-implemented with original
architecture, naming, and structure.

Some of the difficulty/performance curve shapes and constants implemented
here are derived from the publicly documented behaviour of ppy Pty Ltd's
osu! difficulty and performance calculators (MIT Licence, copyright ppy Pty
Ltd, https://github.com/ppy/osu). This notice is included so that
attribution is preserved as required by that licence's terms, even though
senku is not a fork, port, or redistribution of that codebase and is
presented as a general-purpose rhythm game performance calculator.

This does not change senku's own licensing: senku itself is distributed
under the MIT License (see LICENSE), copyright datenshicommunity.
