1//! Generic types for SGFs without a known game.
2//!
3//! This module contains a generic [`SgfProp`] implementation appropriate
4//! for use with any SGF file. This implementation recognizes all [general
5//! properties](https://www.red-bean.com/sgf/properties.html), but any game
6//! specific property will parse as [`Prop::Unknown`].
7//!
8//! SGF Move, Point, and Stone values are all simply stored as strings.
