//! HarfBuzz is a text shaping engine. It solves the problem of selecting
//! and positioning glyphs from a font given a Unicode string.
//!
//! ## Features
//!
//! - `freetype` - Enables bindings to the FreeType font engine. (Enabled by default.)
//! - `coretext` - Enables bindings to the CoreText font engine. (Apple platforms only) (Enabled by default.)
//! - `directwrite` - Enables bindings to the DirectWrite font engine. (Windows only) (Enabled by default.)
//! - `std` - Enable certain functions that require the standard library. (Enabled by default.)
//!
//! - `bundled` - Use the bundled copy of the harfbuzz library rather than one installed on the system.
