+ (Mike Rose) Added calculations for 95th percentile and total data transfer.
  These are still being verified, and must be enabled in the routers.conf

v1.12
= (Pall Wiberg Joensen) Thanks for sending me some DVDs!
+ Modified summary so that you can have different sized graphs. (Now half width
  of your standard graph)

v1.11
! Small change to Javascript to fix problem with speedycgi race condition.
+ More NT-centric help to the INSTALL and PROBLEMS files. Finally I've managed
  to get Apache/ActivePerl/routers.cgi installed on an NT test box here!
! More changes to clean global variables in order to try and make it work with 
  speedycgi.
! Changed description of 4-hour graphs to 6-hour, more accurately reflecting
  their size (can't change graph width as we are already 1 pixel/data point)

v1.10
+ (Trey Valenta) Changed tarball to be in a subdirectory.
+ (Pall Wiberg Joensen) Added 'incoming' and 'outgoing' interface summaries.
+ (Pall Wiberg Joensen) Increased information on Summary page to show numbers.

v1.9
+ Added 'Bookmark' button on graphs pages to create a bookmarkable URL leading
  to this graph page.
! Various additional checks for undefined parameters in case things go amiss.

v1.8
+ Added a few more helpful error messages for misconfigured routers.conf and
  MRTG .cfg files.
! Put in a few more checks for undefined values to stop those web server log
  messages.
+ Added support for 4-hour graphs, if the Sample Interval < 5min.  Also 4hour
  option to routers.conf file.

v1.7
!(Manodj Bisoen) ActivePerl doesnt like %k and so X-axis labels weren't being
  printed on Daily graphs.  Replaced with %H on ActivePerl installations.
+ Make the script try and identify ActivePerl automatically and enable various
  compatibility options.
+ New 'NT' option in conf file to activate NT compatibility things.
! Used '$pathsep' in a URL when it should only be for filenames, this messed up
  NT support a bit.
+ Added legal jargon to more clearly assert GPL status of code

v1.6 15-12-0 NT Compatibility changes
! A number of changes in order to try and make it run more smoothly under NT.
+ A few additions to the PROBLEMS and other documentation files.
+ Split the path separator out into a separate variable to help with NT use.
+ Added 'dbdrive' option to allow NT users to specify which drive the RRDTool
  databases live on (you cant have a drive in the path in an RRDTool function)
  This is not fully tested as I dont have an NT Perl server to test it on.

v1.5b 23-11-0
! Interimn bugfix release
! Removed most (all?) of the constructs that confuse ActivePerl under NT

v1.5 16-11-0
+(Trey Valenta) Added 'png' option in [web] section of .conf file to make the
  system use PNGs instead of GIFs for the graphs.

v1.4a 6-11-0
+(Isaac Grover) Added new option 'maxima' to routers.conf.  This allows you to
  say 'no' and switch off the red 'Max Bandwidth' line, giving auto scaling.
+ Added the example graphstyle line to config file for feature added in v1.2

v1.4 3-11-0
+ Yet more error trapping and sanity checks for people who dont have my style
 of MRTG conf files
=(Isaac Grover) Added extra parsing to cope with user defined OIDs in conf file
!(Paul Joensen) Removed many uses of "$hash{opt}{opt}" which doesnt work well
  in ActivePerl under NT for some reason.  Replaced with string concatenation.

v1.3 1-11-0
+ Added more detailed error messages when parsing errors occur.
!(Scott Neitch, Daniel Szarowicz, Marcelo Rosa) Corrected a few other parsing
 problems affecting the Title and Target lines with non-alpha characters.

v1.2b - not for release.  Interim bugfix version.

v1.2a (bugfix) 19-10-0
!(Scott Shipley) Modified 'Short Name' calculations to take all non-space
 characters, rather than all alpha characters.  This may cause problems on
 some people's configurations.
! Oops, left the mainmenu-red.gif file out of the distro.  Now it's back.
!(Scott Shipley) Fixed reading of interface names to support interface names
 containing '/'.

v1.2
+(Andy Stranks) Added graph Styles options and defaults, for people with
 different sized screens.

v1.1
=(Andy Stranks) Added default interface option in .conf file, instead of
 having it always default to the first interface.

v1.0 21-Aug-2000
+Big modification.  System now takes configuration from a separate conf file,
 and not hardcoded into the script itself!  We've also gone 1.0 as it now has
 relative stability and configurability.  I think.

v0.13  16-Aug-2000
+Added extra code to work out short interface description in case the .ok file
 is not available
!Calculation of .ok file no longer assumes .conf suffix on conf file.
+Added links to web site and acknowledgement at bottom of page

v0.12  11-Aug-2000
