=head1 NAME
dh_installmodules - register modules with modutils
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
use File::Find;
=head1 SYNOPSIS
B<dh_installmodules> [S<I<debhelper options>>] [B<-n>] [B<--name=>I<name>]
=head1 DESCRIPTION
dh_installmodules is a debhelper program that is responsible for
registering kernel modules with modutils.
Files named debian/package.modules will be installed as
etc/modutils/package in the package build directory. This is for use by
modutils. Files named debian/package.modprobe will be installed in
etc/modprobe.d/package in the package build directory, to be used by
module-init-tools's version of modprobe.
Then postinst and postrm commands are automatically generated to register
the modules when the package is installed. See L<dh_installdeb(1)> for an
explanation of how this works. Note that this will be done for any
package this program acts on which has either a package.modules file, or
has .o or .ko files in /lib/modules.
=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 modules file is installed in
etc/modutils/. When this parameter is used, dh_installmodules looks for and
installs files named debian/package.name.modules instead of the usual
debian/package.modules.
=back
=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.
