+Packet builder modules 
+=======================
+
+The packet builder module objective is to build a template packet for a stream and to create a Field engine program to change fields in the packet.
+
+**Some examples for what can be done:**
+
+* Build a IP/UDP/DNS packet and create a range of src_ip = 10.0.0.1-10.0.0.255
+* Build a IP/UDP packets in IMIX sizes 
+
+
+for example this snippet will create SYN Attack::
+
+    # create attack from random src_ip from 16.0.0.0-18.0.0.254 and random src_port 1025-65000    
+    # attack 48.0.0.1 server 
+        
+    def create_stream (self):
+
+        
+        # TCP SYN
+        base_pkt  = Ether()/IP(dst="48.0.0.1")/TCP(dport=80,flags="S")
+
+        pkt = STLPktBuilder(pkt = base_pkt)
+
+        return STLStream(packet = pkt,    #<<<<< set packet builder inside the stream 
+                         mode = STLTXCont())
