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 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.
