saberkit includes constants derived from Retrosheet play-by-play data.

The information used here was obtained free of charge from and is copyrighted
by Retrosheet. Interested parties may contact Retrosheet at

The bundled values are generated by scripts/generate_season_constants.py from
the Chadwick Bureau Retrosheet repository revision recorded in
crates/saberkit-core/src/season_constants_generated.rs. Raw Retrosheet data is
not distributed with saberkit.
