	std2kern is used for updating your kernel-tree from within
	this directory.

	Options:

	-h	This Text.
	-d	Copy depends on file-compare instead on modification date.
	-k DIR	Kerneltree is in DIR instead of /usr/src/linux

	Without any files given, within the whole tree, the "right"
	files are copied. When any files are given in the commandline,
	only those are copied.
