Identifying network devices at boot time.

Hi I boot linux off a USB stick on many different computers with different hardware. How can I determine in a script which devices eth0, eth1, wlan0 exist and which hardware devices they apply too? Sometimes a wireless card is wlan0, other times it is eth1 or even eth3! The proc/net/dev file does not inidicate which hardware is installed. Thanks, Robert Key
