+# which are MAC addresses and hostnames of NICs to send a wakeup packet.
+# Broadcast is used to send the magic packets, so anybody can run the command.
+# Notice that many routers do NOT forward broadcasts automatically!!
+# Comments in the file start with #.

+# Or MAC addresses can be specified on the command line
+#
+# wakeup.pl aa.bb.cc.dd.ee.ff
+#
+# Or both can be used:

+# wakeup.pl -f addresses.cfg 11:22:33:44:55:66

+# Use option -b to specify broadcast mask.
