 =head1 DESCRIPTION
 
-dh_installmodules is a debhelper program that is responsible for
-registering kernel modules with modutils.
+B<dh_installmodules> is a debhelper program that is responsible for
+registering kernel modules.
 
-Files named debian/package.modules will be installed as
-etc/modutils/package in the package build directory.
+Kernel modules are searched for in the package build directory and if
+found, F<preinst>, F<postinst> and F<postrm> commands are automatically generated to
+run B<depmod> and register the modules when the package is installed. 
+These commands are inserted into the maintainer scripts by
+L<dh_installdeb(1)>.
 
-Then postinst and postrm commands are automatically generated to register
-the modules when the package is installed. See L<dh_installdeb(1)> for an
-explanation of how this works. Note that this will be done for any
-package this program acts on which has either the above-mentioned file, or
-has .o files in /lib/modules.
