This defines the parameters for a delay pool.  Each delay pool has
	a number of "buckets" associated with it, as explained in the
	description of delay_class.  For a class 1 delay pool, the syntax is:

delay_parameters pool aggregate

	For a class 2 delay pool:

delay_parameters pool aggregate individual

	For a class 3 delay pool:

delay_parameters pool aggregate network individual

	The variables here are:

		pool		a pool number - ie, a number between 1 and the
				number specified in delay_pools as used in
				delay_class lines.

		aggregate	the "delay parameters" for the aggregate bucket
				(class 1, 2, 3).

		individual	the "delay parameters" for the individual
				buckets (class 2, 3).

		network		the "delay parameters" for the network buckets
				(class 3).

	A pair of delay parameters is written restore/maximum, where restore is
	the number of bytes (not bits - modem and network speeds are usually
	quoted in bits) per second placed into the bucket, and maximum is the
	maximum number of bytes which can be in the bucket at any time.

	For example, if delay pool number 1 is a class 2 delay pool as in the
	above example, and is being used to strictly limit each host to 64kbps
	(plus overheads), with no overall limit, the line is:

delay_parameters 1 -1/-1 8000/8000

	Note that the figure -1 is used to represent "unlimited".

	And, if delay pool number 2 is a class 3 delay pool as in the above
	example, and you want to limit it to a total of 256kbps (strict limit)
	with each 8-bit network permitted 64kbps (strict limit) and each
	individual host permitted 4800bps with a bucket maximum size of 64kb
	to permit a decent web page to be downloaded at a decent speed
	(if the network is not being limited due to overuse) but slow down
	large downloads more significantly:

delay_parameters 2 32000/32000 8000/8000 600/8000

	There must be one delay_parameters line for each delay pool.
