+          Starting from <package>perl</package> 5.12.3-2, a dpkg trigger
+          named <var>perl-major-upgrade</var> will be triggered by the

+          directories in <tt>@INC</tt>, or one which changes <tt>abiname</tt>.
+          Any package may declare an interest in the trigger, especially

+          until restart.
+        </p>
+        <p>
+          It is suggested that such packages include an appropriate section
+          in their postinst to handle the trigger by restarting relevant
+          daemons or notifying users of further action.
