V0.9 - initial revision

V0.91:
Added time zone arithmetics
fixed bug in ipacsum: no input files and -r
added CHANGES file
corrected documentation

V0.93:
Improved -t time frame syntax
Added graph support
Added -f filter option

V0.94:
Fix: no longer produce readdir() warning
-s and -e can take relative times, too
minor fixes

V0.95:
Added official distribution site
Added -d option to ipacsum
Avoided warnings

V0.96:
- ipacsum:
        better handle corrupt data file content
- ipacset + fetchipac:
        be more robust about missing permissions or RUNFILE
        don't call fetchipac on initial call at boot time
        handle all lock file cases correctly

V0.97:
- subst.c: fixed compile error under libc6 / RedHat 5.1
- ipacsum: fixed (nearly) endless loop when no start time was given and -g

V0.98 (98/07/14):
- changed default lock file directory from /tmp to /var/lock (security)
- ipacset: discovered ipfwadm may add more than one line to the kernel
	tables with one call - this happens when a host name resolves to
	more than one ip address. As a result, all gathered data were 
	messed up. Fixed ipacset to handle this properly.
These changes to ipacset were done by Friedrich Lobenstock 
<fl@fl.priv.at> [FL], thanks!:
  - Fixed a bug if there exist empty lines in /etc/ipac.conf
  - Added some basic syntax checking (empty parameters)
  - Added command line option '-D' for debugging
  - Not really added support for bidirectional rules.
	Just say 'io'(or 'both' as in ipfwadm(8)) instead of
	'in' or 'out' in /etc/ipac.conf
- README: Added hint to mailing list
- support for long option names

V0.99 (98/07/29)
- added man pages
- corrected many spelling errors (discovered ispell). Changed "--intervall"
	option of ipacsum to "--interval" :-). (Old version still works)
- added gif image creation (all options beginning with --gif)
- added --version

V1.00 
- improved ipacset error handling
- fixed order of week days in ipacsum
- added average value feature for gif pictures
- --gif-caption-in-index / show max and average values in html index file
- --show-run-progression / display a progression indicator while running
- added "Resolution:" in index.html
- support for empty interface spec in ipac.conf for "any interface"
- --gif-asis, HTTP Expires: header lines and HTML META tags
- can now define two or more rules with the same name. ipac shows the
	sum in its outputs

V1.01
- fixed 'Illegal division by zero at /usr/local/bin/ipacsum line 763.'
- minor sub-pixel fix in gif creation (probably never visible)

V1.03 (1999/05/10)
- fixed bugs in ipacset and fetchipac which appeared with some shells
- added handling of cases when something deletes some or all of ipac's
	settings in the kernel (ipacset --fix-chains, fetchipac corrupted
	kernel settings detection, "BUGS" section in ipacset(8))

V1.04 (1999/05/31)
- bug fix concerning ipchains option --fix-chains (still had problems with
	firewall scripts)
