       [-c [-d max_depth] [-s min_support] [-r]] [-t]

	-i: use ./radar to produce an index
	-a: auto mine
	-m: limit memory usage to approximately this amount (in bytes)
	-f: use this as the prefix for the index name

	-p: prints the index
	-c: count all associations to max_depth, using min_support frequency, optionally restarting (-r) from an assoc given on stdin
	-t: tests an indexed database against an assoc file, read from stdin
