-- Adds capability for OpenBSD APM info in ion3 statusbar.
--
-- Originally written by Greg Steuck and released into the Public Domain
-- 2006-10-28 modified by Darrin Chandler <dwchandler@stilyagin.com>
-- to work with OpenBSD 4.0 apm output.
--
-- To install:
-- Save this file as ~/.ion3/statusd_apm.lua,
-- Change ~/.ion3/cfg_statusbar.lua like so:
-- Add "apm={}," to mod_statusbar.launch_statusd,
-- Modify "template" to include %apm_ variables
-- e.g. template="[ %date || load:% %>load || bat: %apm_pct%%, A/C %apm_ac ],"
--
-- Available variables:
-- %apm_state high, low, critical
-- %apm_pct battery life (in percent)
-- %apm_estimate battery life (in minutes)
-- %apm_ac External A/C charger state
-- %apm_mode Adjustment mode (manual, auto, cool running)
-- %apm_speed CPU speed
