//! This is a crate for using
//! [OpenPGP card devices](https://en.wikipedia.org/wiki/OpenPGP_card) with
//! the [`rPGP`](https://crates.io/crates/pgp) OpenPGP library.
//!
//! In fact, this crate is a supplement for the
//! [`openpgp-card`](https://crates.io/crates/openpgp-card) crate.
//! This crate, `openpgp-card-rpgp`, enables performing OpenPGP-specific
//! operations on cards, by leveraging both the `rPGP` library and `openpgp-card`.
//! If you want to use this crate, you will probably also want to use
//! `openpgp-card` itself:
//!
//! Much of the functionality of an OpenPGP card device doesn't actually
//! involve the OpenPGP format. All of that functionality is available in
//! `openpgp-card`, without requiring support for the OpenPGP format.
//!
//! This crate implements additional support for operations that *do* require
//! handling the OpenPGP format:
//!
//! - Creating OpenPGP signatures
//! - Decryption of OpenPGP data
//! - Import of OpenPGP private key material
//!
//! See this project's "examples" for some pointers on how to use this crate.
