verovio-data 0.3.2

//! SMuFL font and resource files for the [Verovio](https://www.verovio.org/)
//! music notation engraver.
//!
//! Verovio refuses to parse any input until `Resources::Ok()` returns true,
//! which requires the font data on disk at the path passed to
//! `Toolkit::SetResourcePath`. This crate bundles the resource tree at compile
//! time and offers [`extract`] to stage it onto a real filesystem so Verovio
//! can read it.
//!
//! The bundled contents are an exact mirror of the `data/` directory in the
//! Verovio source tree pinned by the `verovio-sys` crate. Both Bravura
//! (mandatory) and Leipzig (eager-loaded) are included, plus the optional
//! Gootville, Leland, Petaluma, and Liberation fonts.
