v0.7
~~~~
The script is now updated to work with rrdtool v1.2.x. I'm not
sure if it still works with 1.0.x. Feel free to let me know if
it does/doesn't. There are no bugfixes in this release, so 
if you're still using 1.0.x, there's no compelling reason to
upgrade.
Added the '-E' option to the rrd command line to create more
'organic' looking graphs.
Added in a 3 year graph as some of my data has long since
scrolled off the 1 year graph.

v0.6.1
~~~~~~
Fixed a small bug that caused the script to output incorrect
html for one of the graphs when using the inverse option...
Whoops. Thanks goes to Gene Nazarov (genen at Ameripay dot com)
for pointing this out!

v0.6
~~~~
Added suport for different protocols (UDP/TCP) as if you're
balancing two different services on the same port, but with
different protocols, the script would try to update the same
file twice, likely with completely differnt data. This is Bad(tm).
This was submitted by Xavier (xavier at rootshell dot be). 
Thanks Xavier!
The update script will automatically change the filenames, so
you shouldn't have to do anything except clean up the old files 
(see the UPGRADE section in the README)

Added a line to the php page so the images are cached for up to 
5 minutes. A small change, but I might as well make use of the
php, right?

Added a verbose option to the graphing script.

v0.5
~~~~
Fixed a bug that caused systems with the same real servers
in more than one VIP to have all data equal the last VIP's data.
Thanks goes to Ryan Clark for pointing out this bug!

v0.4
~~~~
Added an option "-s" that outputs a separate graph (the 
second named with a "-I" just before the ".gif") for active
and inactive connections. This is useful for people with
lopsided data (ie: 7000 inactive and 5 active) which is common
w/ masq setups.

Some code cleanup. 

v0.3
~~~~
Changed the version naming scheme. Looks nicer.

Renamed the rrd files to accomodate more flexibility in graphing.

Renamed the rrd update script (easier to upgrade this way, plus
the new name makes more sense).

Added several command line options to allow more refined graphing,
instead of everything on one graph. 

Changed the lazy option to exit the script early on instead of leaving
it up to rrd's lazy option. Makes the option actually useful
in the case of this script.

Added an option to flip the graph for people with more inactive than 
active connections.

Lots of code cleanups and bug fixes.

Other things I can't remember.

~~~~~~~~
Added a command line argument so individual ports can be graphed
instead of everything in one graph.

Changed the way the colors are selected so that the users can
choose have the script add or subtract either red green and/or 
blue, or just set them to a specific value for all servers. 

Added a bunch of variables so that all sorts of other colors can 
be changed (such as the background, the canvas colors, the font 
color, etc etc etc.)
