-          they have been replaced by functions in /sys.
-          The deprecated directories (and their replacements) include:
-	  /proc/acpi/battery/* (/sys/class/power_supply/*)
-	  /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
-	  This option has no effect on /proc/acpi/ directories
-	  and functions, which do not yet exist in /sys
-	  This option, together with the proc directories, will be
