# Convert arp.dat to ethers format
#
#	- sort on timestamp, newest first
#	- discard entries without simple hostnames
#	- discard all but first occurance of each ethernet address
#	- discard entires with raw ip addresses for simple names
#	- remove ip address and timestamp fields
#	- append "-ip" to hosts with decnet address too
#	- append "-old", "-old1", etc. as necessary
#	- sort
