use File::Find;

=head1 SYNOPSIS

B<dh_installudev> [S<I<debhelper options>>] [B<-n>] [B<--name=>I<name>] [B<--priority=>I<priority>]

=head1 DESCRIPTION

B<dh_installudev> is a debhelper program that is responsible for
installing B<udev> rules files.

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

=head1 FILES

=over 4

=item debian/I<package>.udev

Installed into F<lib/udev/rules.d/> in the package build directory.

=back

=head1 OPTIONS

=over 4

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

When this parameter is used, B<dh_installudev> looks for and
installs files named debian/I<package>.I<name>.udev instead of the usual
debian/I<package>.udev.

=item B<--priority=>I<priority>

Sets the priority the file. Default is 60.

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

Do not modify F<preinst>/F<postinst> scripts.

=back

=head1 NOTES

Note that this command is not idempotent. L<dh_prep(1)> should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
