  18 =head1 DESCRIPTION
  19
  20 dh_installudev is a debhelper program that is responsible for
  21 installing udev rules files.
  22
  23 Files named debian/package.udev will be installed as
  24 etc/udev/package.rules in the package build directory.
  25
  26 Then postinst and postrm commands are automatically generated to enable
  27 the rules file when the package is first installed, by creating a symlink
  28 to it in the /etc/udev/rules.d/ directory. See L<dh_installdeb(1)> for an
  29 explanation of how this works.

  34
  35 =item B<-n>, B<--noscripts>
  36
  37 Do not modify postinst/postrm scripts.
  38
  39 =item B<--name=>I<name>
  40
  41 Use "name" as the filename the rules file is installed in
  42 /etc/udev/. When this parameter is used, dh_installudev looks for and
  43 installs files named debian/package.name.udev instead of the usual
  44 debian/package.udev.
  45
  46 =item B<--priority=>I<priority>
  47
  48 Sets the priority string of the rules.d symlink. Default is z60.

  53
  54 Note that this command is not idempotent. "dh_clean -k" should be called
  55 between invocations of this command. Otherwise, it may cause multiple
  56 instances of the same text to be added to maintainer scripts.
