=head1 NAME

dh_installudev - install udev rules files

=cut

use strict;
use Debian::Debhelper::Dh_Lib;
use File::Find;

=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 in
etc/udev/rules.d/ in the package build directory.

Code is added to the preinst and postinst to handle the upgrade from the
old udev rules file location.

=head1 OPTIONS

=over 4

=item B<--name=>I<name>

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.

=item B<-n>, B<--noscripts>

Do not modify postinst/postrm scripts.

=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.
