      Allows user authentication and digital signatures with Belgian ID cards.
      Also requires a running pcscd service and compatible card reader.

      eid-viewer is also installed.

      This package only installs the libraries. To use eIDs in Firefox or
      Chromium, the eID Belgium add-on must be installed.
      This package only installs the libraries. To use eIDs in NSS-compatible
      browsers like Chrom{e,ium} or Firefox, each user must first execute:
        ~$ eid-nssdb add
      (Running the script once as root with the --system option enables eID
      support for all users, but will *not* work when using Chrom{e,ium}!)
      Before uninstalling this package, it is a very good idea to run
        ~$ eid-nssdb [--system] remove
      and remove all ~/.pki and/or /etc/pki directories no longer needed.

      The above procedure doesn't seem to work in Firefox. You can override the
      firefox wrapper to add this derivation to the PKCS#11 modules, like so:

          firefox.override { pkcs11Modules = [ pkgs.eid-mw ]; }
    '';

    maintainers = with maintainers; [ bfortz ];
  };
