2003/03/13	version 0.7

2003/03/12	aguri_tree.c:
		check if (thresh == 0) in leaf_reclaim().

2003/03/11	aguri.c, aguri_ip.c, aguri_pcap.[ch]:
		print pcapstat on SIGUSR1 for debug.

2003/02/28	aguri_tree.[ch]:
		improve the reclaim algorithm by combining the new subtree
		reduction method with the previous leaf_free method.
		the idea is that, when we select a victim leaf,
		 - if parent is larger than sibling's subtree, reduce
		   parent's subtree into a single node
		 - if sibling's subtree is larger, remove the victim and
		   the parent by leaf_free()
		as a by-product, tree_init() and tree_destroy() become
		simpler.

		aguri.c:
		change the default lru_size from 256 to 512.
		outputs become much better for backbone networks,
		and increased overhead is negligible.

		Makefile:
		xtree is for demo and not needed for the default installation.
		use -O2 for CFLAGS.

2003/02/24	aguri.c, aguri_pcap.[ch]:
		need to call pcap_compile() and pcap_setfilter() to set
		the snap length since bpf implements the snaplen by bpf code.
		add [-f filter_cmd] option as a by-product.

2003/02/20	scripts/makeimages.pl:
		create weekly images and 3D images as well.

		scripts/makeplot.pl:
		add "-3D" option to create 3D plot images
		the original work was done by Tsuji Naoya <n-tsuji@jaist.ac.jp>

2003/02/19	add scripts/makeimages.pl
		to create daily png plot images and index.html

		scripts/agurify.pl:
		add the <interface> directory under the log directory
		to support more than 2 interfaces.
		  change from <aguri.log>/<year>/<month>/<day>/
			 to   <aguri.log>/<ifname>/<year>/<month>/<day>/

		change the default output interval from 5 seconds to
		10 seconds, and the recommended HUP interval from 2
		minutes to 5 minutes.

2003/02/09	read_pcap.c:
		support OpenBSD pflog
		submitted by Jose Nazario <jose@monkey.org>

2002/10/23	internal release version 0.6

		aguri_plot.c:
		fix a bug for IPv6 in the plot mode.

2001/03/26	fix a bug in ipv6 option header chasing

2001/03/22	verion 0.5 (first public release)
