Change 127722 by jb at jb_freebsd1 on 2007/10/18 21:33:21

	Add a release build tool which is designed to create
	a specified file with it's modification time set to
	the most recent modification time of the file/s in the
	directory trees it is asked to search.
	
	latest ${.OBJDIR}/woof /usr/src
	
	will look recursively through /usr/src for the most
	recently updated source file and ${.OBJDIR}/woof will
	have it's timestamp sent to match it.
	
	Obviously, if no source files have changed since the
	last buildworld, then it's a fair bet that another
	buildworld isn't required.
