statusd_linuxbatt_sys.lua

-- statusd_linuxbatt.lua
--
-- Public domain
--
-- Uses the /proc/acpi interface to get battery percentage.
--
-- Use the key "linuxbatt" to get the battery percentage; use
-- "linuxbatt_state" to get a symbol indicating charging "+",
-- discharging "-", or charged " ".
--
-- Now uses lua functions instead of bash, awk, dc.  MUCH faster!
--
-- Hacked to make it work with new kernels (with interface moved to /sys)
-- Rename to statusd_linuxbatt.lua to use
--
-- The "bat" option to the statusd settings for linuxbatt modifies which
-- battery we look at.
