=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)
