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

      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.
