>+
>+
>+
>+There are two methods:

>+
>+<ul>

>+ <li>"consolekit": identifies users who are sat in front of the computer,
>+ and grants them access;</li>
>+ <li>"plugdev": allows members of the plugdev group to use bluetooth</li>
>+</ul>
>+
>+
>+Although the permission policy can be tuned by editing the dbus permission rules
>+for <c>bluez</c>, the <c>consolekit</c> USE flag must be set accordingly
>+
>+
>+<ul>
>+ <li><c>consolekit</c> &mdash; means the consolekit method is used and requires
>+ it to be enabled in some dependencies</li>
