            To generate a new user database, create a text file, add
            your users using the following format:
            <programlisting>
            user1
            password1
            user2
            password2
            </programlisting>
  
            You can then install <literal>pkgs.db</literal> to generate
            the Berkeley DB using
            <programlisting>
            db_load -T -t hash -f logins.txt userDb.db
            </programlisting>
  
            Caution: <literal>pam_userdb</literal> will automatically
            append a <literal>.db</literal> suffix to the filename you
            provide though this option. This option shouldn't include
