$0 [OPTION]

	Builds the kernel repeatedly in a loop.

	This has been known to cause crashes with unstable hardware
	or device drivers.

	-l numeric level
		1 - stop after make
		2 - stop after make modules_install
		3 - complete to make install
	   Default is 3, complete to make install.

	-c sparse level
		1 - sparse only for newly compiled sources
		2 - sparse for all sources

	-j number of cpu cores to use (default is all cores)
	-b build versioning string
	-v verbose make
	-h this help screen

	With no options, each make in the loop will build and install
	the kernel and kernel modules using all processors.

	The loop stops if the build fails.
