/* wmnet -- X IP accounting monitor
* Copyright 1998 Jesse B. Off
* Copyright 2000 Katharine Osborne

* This software is released under the GNU Public License agreement.
* No warranties, whatever.... you know the usuals.... this is free
* software. if you use it, great... if you wanna make a change to it,
* great, but please send me the diff.
*
* CHANGELOG:
* 3/24/1998 -- First release, wrote this yesterday, so it may have
* some bugs.
* 3/25/1998 -- added logarithmic scaling.
* some touch ups on the updateSpeedometer() to be a
* little more helpful
* added a little more width to the speedometer display
* from a report that the text sometimes was drawn off
* the scale (couldnt confirm, is it fixed?)
* fixed prob for speeds > 9.9 megabytes per second (I
* think... I can't go that fast myself
* Made default maxspeed 6000 which I assume is better
* for modems.
* 5/11/1998 -- I witnessed the little problem with the speedometer
* going off into the main window so I set a clipmask
* Still don't understand how it could go off..I'm
* using a fixed size font...
* 5/13/1998 -- Modified the way it gets its stats from /proc/net/ip_acct
* You now have to give it explicit accounting rule numbers
* through the -T and -R options or else it defaults to the
* fist two in tx, rx order, best just to make sure
* you set the -T and -R options.
* 5/15/1998 -- Completed interface rewrite, definitely have more graphing
* space, but I dont know if I like it yet.
* 5/16/1998 -- Added shaded graphs, xload style. Its a lot prettier!
* 5/20/1998 -- Fixed afterstep wharfability problem... should also atleast
* display in other WM's
* 6/16/1998 -- Fixed handling of WM_DELETE_WINDOW, strtol() to strtoul(),
* and now uses getopt_long.
* 6/16/1998 -- Put in --withdrawn and --normalstate options to explicitly
* set the type. Still tries to auto-detect wmaker though.
* 6/16/1998 -- Put in --execute and --promisc options.
* 6/17/1998 -- Some code clean-ups.
* 6/18/1998 -- Implemented a labeling mechanism.
* 6/18/1998 -- Slowed down the speedometer display... it was getting annoying.
* 6/23/1998 -- Split up to wmnet.c and wmnet.h
* 8/5/1998 -- New options --device and --driver
* 5/4/2000 -- Support added for OpenBSD
