How to get info into HAL?

[bsmith]

Hi
    I'm writing a battery driver for an ARM system and
I'd like HAL to keep the battery info.  HAL sees the /sys
entry but it needs the current_charge info.

- How do you get a property into HAL?
- Is is part of the configuration in one of the udi files?
- Does it need to be hard coded into a helper app?
- If the later, how does HAL tie to the helper app?
- Is there a programer's manual that describes all this?

thanks

udi = '/org/freedesktop/Hal/devices/platform_battery_0'
   info.udi = '/org/freedesktop/Hal/devices/platform_battery_0'  (string)
   linux.subsystem = 'platform'  (string)
   linux.hotplug_type = 1  (0x1)  (int)
   info.product = 'Platform Device (battery.0)'  (string)
   platform.id = 'battery.0'  (string)
   info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
   info.bus = 'platform'  (string)
   linux.sysfs_path_device = '/sys/devices/platform/battery.0'  (string)
   linux.sysfs_path = '/sys/devices/platform/battery.0'  (string)
