+=head1 SYNOPSIS
+
+B<dh_installudev> [S<I<debhelper options>>] [B<-n>] [B<--name=>I<name>] [B<--priority=>I<priority>]
+
+=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.
+
+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.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify postinst/postrm scripts.
+
+=item B<--name=>I<name>
+
+Use "name" as the filename the rules file is installed in
+/etc/udev/. When this parameter is used, dh_installudev looks for and
+installs files named debian/package.name.udev instead of the usual
+debian/package.udev.
+
+=item B<--priority=>I<priority>
+
+Sets the priority string of the rules.d symlink. Default is z60.
+

+
+=head1 NOTES
+
+Note that this command is not idempotent. "dh_clean -k" should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
