//! ## [Documentation](https://docs.rs/clang-sys)
//!
//! Note that the documentation on https://docs.rs for this crate assumes usage
//! of the `runtime` Cargo feature as well as the Cargo feature for the latest
//! supported version of `libclang` (e.g., `clang_11_0`), neither of which are
//! enabled by default.
//!
//! Due to the usage of the `runtime` Cargo feature, this documentation will
//! contain some additional types and functions to manage a dynamically loaded
//! `libclang` instance at runtime.
//!
//! Due to the usage of the Cargo feature for the latest supported version of
//! `libclang`, this documentation will contain constants and functions that are
//! not available in the oldest supported version of `libclang` (3.5). All of
//! these types and functions have a documentation comment which specifies the
//! minimum `libclang` version required to use the item.
