A script to enable laptop power saving features for #! & Debian GNU+linux.
Generally speaking, this script should automatically switch powertop's 
"Tunables" which proved to make significant impact in power consumption 
while running on battery.

Adjusted to own needs and github'ed by Dawid Lorenz / [email protected]

To make this script run each time laptop's power adapter is plugged in/out:
sudo cp powersave /etc/pm/power.d/
sudo chmod +x /etc/pm/power.d/powersave

To run script manually:
./powersave true|false

Tested on Fedora 15, please review script and run it manually before putting
under /etc/pm/power.d/
