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.
