 =head1 DESCRIPTION
 
-dh_installudev is a debhelper program that is responsible for
-installing udev rules files.
-
-Files named debian/package.udev will be installed as
-etc/udev/package.rules in the package build directory.
+B<dh_installudev> is a debhelper program that is responsible for
+installing B<udev> rules files.
 
-Then postinst and postrm commands are automatically generated to enable
-the rules file when the package is first installed, by creating a symlink
-to it in the /etc/udev/rules.d/ directory. See L<dh_installdeb(1)> for an
-explanation of how this works.
+Code is added to the F<preinst> and F<postinst> to handle the upgrade from the
+old B<udev> rules file location.
