Changes: Added ability for Linux 2.2 to use /proc for
gathering stats, which allows monitoring any device that
reports bytes in/out to /proc/net/dev including ppp, eth, plip,
lo, etc... without any special accounting rules, fixed unsigned
"negative" number rate problem, rewrote back-end to be more
modular, added a -nochart option (labels only) and removed
fallback geometry.
Changes: Fixed some X errors that happened under Solaris concerning
zero sized widgets, added user customizable scales, changed rate
labels to show b/s, k/s, M/s dependant on magnitude, added horizontal
orientation option.
