  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.

  42 installs files named debian/package.name.udev instead of the usual
  43 debian/package.udev.

  52
  53 Note that this command is not idempotent. "dh_clean -k" should be called
  54 between invocations of this command. Otherwise, it may cause multiple
  55 instances of the same text to be added to maintainer scripts.
