-# ethers	This file contains 48 bit Ethernet addresses and their
-#		corresponding IP number or hostname. The two items are
-#		separated by any number of SPACE and/or TAB char acters.
-#		A at the beginning of a line starts a comment which extends
-#		to the end of the line. The Ethernet-address is written as
-#		x:x:x:x:x:x, where x is a hexadecimal number between 0 and
-#		ff which represents one byte of the address, which is in
-#		network byte order (bigendian). The IP-number may be a
-#		hostname which can be resolved by DNS or a dot separated
-#		number.
-#
-# Syntax:
-#	Ethernet-address	IP-number

-# netgroup      The netgroup file. Entries look like this:

-#               So for example a netgroup for powerusers could be:
