The goal of wmhdaps is to provide a tool
for configuration of the Harddisk Active Protection System (HDAPS)
found in some R/G/T thinkpad models. HDAPS is realized as 
an acceleration sensor mounted on systemboard and a 
userspace tool which detects based on acceleration values from sensor 
shocks and freezes the harddrive(s) until the "shock" is over.

In version 0.03 the algorithm to determine 
average velocity, velocity, and acceleration is adapted 
from the hdapsd demon. These values are visualized by 3 bars.
If you have the harddisk protection patch applied and the
hdapsd demon is running, it also will observe the protection 
status of the given drive (default: hda) and show a lock 
while the protection is active. Again: wmhdaps is only 
a nice looking monitoring tool. It doesn't do the
protection stuff by itself.

In Version 0.04 redraws only occur when something changed.
This helps to save power. As it doesn't redraw constantly 
it gives the notbook a chance to enter the power states C3/C4. 
Nathan Lay kindly contributed the port of wmhdaps for FreeBSD. 
Use Makefile.FreeBSD to compile on FreeBSD.
