+	  Simplified modutils.

+	  With this option modprobe does not use or require
+	  modules.dep or /etc/modules.conf files.
+	  It scans module files in /lib/modules/`uname -r` and
+	  determines dependencies and module alias names on the fly.
+	  This may make module loading slower, most notably
+	  when one needs to load module by alias (this requires
+	  scanning through module _bodies_).
+
+	  Additional module parameters can be stored in
+	  /etc/modules/$module_name files.
+
+	  Apart from modprobe, other utilities are also provided:
+	  - insmod is an alias to modprobe
+	  - rmmod is an alias to modprobe -r
+	  - depmod is provided but does nothing
+
+	  As of 2008-07, this code is experimental. It it 15kb smaller
