$NAME:    $NAME
$NAME: 
$NAME:   Nmap is a utility for network exploration or security auditing. It
$NAME:   supports ping scanning (determine which hosts are up), many port 
$NAME:   scanning techniques (determine what services the hosts are offering),
$NAME:   and TCP/IP fingerprinting (remote host operating system ID). Nmap
$NAME:   also offers flexible target and port specification, decoy scanning,
$NAME:   determination of TCP sequence predictability characteristics, sunRPC
$NAME:   scanning, reverse-identd scanning and more. Not compiled with
$NAME:   nmapfe, but as the Makefile says: "GUIs are for wusses"
