+=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.
+
+=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
+

+
+=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.
