sorter.sh

#!/bin/bash -e

#
#	Sorts out all built modules to module extensions, and a tarball for what goes in the base.
#
#	Before running, do a "make INSTALL_MOD_PATH=/tmp/somewhere/usr/local modules_install" and
#	any other preprocessing, like gzipping the modules and removing generated files in
#	lib/modules/KERNELVER.
#	Things will happen in the current directory.
#
#
#	Usage:		./sorter.sh KERNELVER PATH
#	Example:	./sorter.sh 2.6.33-tinycore /tmp/somewhere
