====== Eee PC Customizations ======

Some Eee PC customizations via shell script
  * Disable suspend to ram when AC adapter is plugged in and the lid is closed.
    * 30 minute timeout, after which the computer is suspended anyways
  * If the lid is closed and the AC adapter is unplugged, then suspend to ram is run.
  * Lock the screen if the lid is closed unless you're at home (checked via wireless connection)
  * Lock the screen if the screen blanking button is pressed unless you're at home
