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. + +=head1 OPTIONS + +=over 4 + +=item B<-n>, B<--noscripts> + +Do not modify postinst/postrm scripts. + +=back + +=head1 NOTES + +Note that this command is not idempotent.
