=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
B<dh_installmodules> is a debhelper program that is responsible for
registering kernel modules.
Kernel modules are searched for in the package build directory and if
found, F<preinst>, F<postinst> and F<postrm> commands are automatically generated to
run B<depmod> and register the modules when the package is installed.
These commands are inserted into the maintainer scripts by
L<dh_installdeb(1)>.
=head1 FILES
=over 4
=item debian/I<package>.modprobe
Installed to etc/modprobe.d/I<package>.conf in the package build directory.
=item debian/I<package>.modules
These files were installed for use by modutils, but are now not used
and B<dh_installmodules> will warn if these files are present.
=back
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify F<preinst>/F<postinst>/F<postrm> scripts.
=item B<--name=>I<name>
When this parameter is used, B<dh_installmodules> looks for and
installs files named debian/I<package>.I<name>.modprobe instead
of the usual debian/I<package>.modprobe
=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.
