/*
	Very useful program to remove root path dir.
	Root path dir is bad because filenames are very long
	and you only get two columns of display in nccnav.

	Sample Usage:
find . -name \*.nccout | xargs cat | pathremover /mnt/sources/hacks/linux-2.40.2/ > Code.map

	the path argument must end in '/' to do it right.
