+=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 <[e-mail]> 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...
+
+=item B<--verbose>
+
+Be verbose (not implemented)
