+//! # Rust audio oscillator for the Godot game engine
+//!
+//! This crate contains logic for generating samples for audio wave forms which are then
+//! used to fill Godot's `AudioStreamPlayback` buffers. Scripts using this code as a dynamic
+//! library will be able to request a certain number of frames (represented as a `Vector2`)
+//! at a specific frequency. Because of how the Godot bindings work, the wave structs will
+//! have a default sample rate at 48kHz. You'll want to set it in your script's `_ready`
+//! function to match the sample rate in Godot.
