Content type:	text/plain
Branch:	MAIN
Log Message:	Initial version. Only compiled on solaris - but seems to work. Makes use of efA flags, and also a 'o' flag for sorting.. ps -o cpu ps -o mem will sort by that type. Need to do the -n flag still (not look up names - although, is there much point to that?)
