#Platform: ALT Linux (Mandrake-based optional)
#Language: GNU C
#Desription:
It is VERY powerfull program, which includes: packet creator + packet sender, 
packet sniffer, portscanner. So, you can do almost everything with this one 
program. Only shortcoming of this software, that it can be used by people expe-
rienced in internetwork protocol.
#How to use:
Params are:
 mkip - creates IP header
 mk_i - creates ICMP header
 mk_u - creates UDP header
 mk_t - creates TCP header
 mksm - fills packet with symbol
 snrp - sniffes packets, but do not decodes anything
 snip - sniffes packets, decodes only IP header
 snap - sniffes packets, decodes everything
 sdpk - sends packet
 scpr - scans ports
Detailed params are:
