The usage of Send Packet is pretty easy. As you can see, you can set
the default behavior of the program, that is, when no arguments are
passed to Send Packet in the file config.h.
However, you can modify, in any time you want, this options via the
command line options below:

-size <n>: Will specify the buffer length. That is, the maximum ammount of
	   octets in the packet.
-src <ip>: Source IP address of the packet to send.
-dst <ip>: Destiny IP address of the packet to send.	 
-sprt <n>: Source port of the packet to send. (Only applied to udp and
	   tcp packets).
-dprt <n>: Destiny port of the packet to send. (Only applied to udp and
	   tcp packets).
-sname <host>: Use this option instead of -src if you do know the source
	       hostname but not the IP address. Send Packet will try to
	       'guess' the IP address.
-dname <host>: Use this option instead of -dst if you do know the destiny
	       hostname but not the IP address. Send Packet will try to
	       'guess' the IP address.
-seq <n>: Send tcp packet with sequence number 'n'. Only for TCP.
-ack <n>: Send tcp packet with an ack sequence number of 'n'. Only for TCP.
-w <n>: Sets window size to 'n'. Only for TCP.
-f  <flag>: TCP flag. flag can be any of: "ack", "syn", "fin", "urg", "psh"
	    "rst". Only for TCP.
-ttl <n>: Send ip protocol with a time to live 'n'.
-proto <p>: Use protocol "p" as default. p can take any of the 
	    following values: "tcp", "udp", or "icmp" (without the quotes).
-msg <msg>: Send icmp message "msg". msg can be: "echo", "echoreply",
	    "destunreach", "srcquench", "redirect", "timexceeded", 
	    "parameterprob", "timestamp", "timestampreply", "inforequest",
	    "inforeply", "address", "addressreply". Only for ICMP.
-code <n>: n can be 0-12 and is used with msg types: "destunreach",
	   "srcquench", "redirect", "timexceeded". The meaning of n is
	   different for each kind of message. See <netinet/ip_icmp.h>
	   for details. Only for ICMP.
-to <ip>: IP address. i.e: Needed when sending a destination for an icmp 
	  redirect. Only for ICMP.
-host <ip>: Used with ICMP to specify wich host reported the msg or problem.
	    i.e: icmp redirect "host" to "to". 
-file <file>: Location of the file to be used as data-file.
-sendfile: sends the content of the data file too.
-h: Help, options, and copyright info.

NOTE: If you ommit any of the above options, Send Packet will use its
default values at the time of compiling.
