// To use this, make sure that you have vpcd from vsmartcard installed and configured (e. g.
// install vsmartcard-vpcd on Debian).  You might have to restart your pcscd, e. g.
// `systemctl restart pcscd pcscd.socket`.
//
// Now you should be able to see the card in `pcsc_scan` and talk to it with `gpg --card-status` or
// with this code snippet using `openpgp-card-client`:
//
//    let context = pcsc::Context::establish(pcsc::Scope::User)
//        .expect("failed to establish context");
//    let readers = context.list_readers_owned()
//        .expect("failed to list readers");
//    assert!(readers.len() > 0);
//    let card = context.connect(&readers[0], pcsc::ShareMode::Shared, pcsc::Protocols::T1)
//        .expect("failed to connect card");
//    let mut client = openpgp_card_client::Client::new(card).expect("failed to create client");
//    assert!(client.verify(b"12345678").is_err());
//    assert!(client.verify(b"123456").is_ok());
//

// Set `RUST_LOG=opcard::card=info` to see the executed commands.
