 * This plugin monitors battery usage on ACPI-enabled systems by reading the
 * battery information found in /sys/class/power_supply. The update interval
 * defaults to 9 second.
 *
 * The battery's remaining life is estimated from its current charge and current
 * rate of discharge. The user may configure an alarm command to be run when
 * their estimated remaining battery life reaches a certain level.
