		=head1 NAME

		depmod.pl - a cross platform script to generate kernel module dependency
		lists which can then be used by modprobe.

		=head1 SYNOPSIS

		depmod.pl [OPTION]... [basedir]...

		Example:

		depmod.pl -F linux/System.map target/lib/modules

		=head1 DESCRIPTION

		The purpose of this script is to automagically generate a list of of kernel
		module dependancies. This script produces dependancy lists that should be
		identical to the depmod program from the modutils package. Unlike the depmod
		binary, however, depmod.pl is designed to be run on your host system, not
		on your target system.

		This script was written by David Schleef <ds@schleef.org> to be used in
		conjunction with the BusyBox modprobe applet.

		=head1 OPTIONS

		=over 4

		=item B<-h --help>

		This displays the help message.

		=item B<-b --basedir>

		The base directory uner which the target's modules will be found. This
		defaults to the /lib/modules directory.

		=item B<-k --kernel>

		Kernel binary for the target. You must either supply a kernel binary
		or a kernel symbol file (using the -F option).

		=item B<-F --kernelsyms>

		Kernel symbol file for the target. You must supply either a kernel symbol file
		kernel binary for the target (using the -k option).

		=item B<-n --stdout>

		Write to stdout instead of modules.dep. This is currently hard coded...
		kernel binary for the target (using the -k option).

		=item B<--verbose>

		Be verbose (not implemented)
