+Howdy do neighbor!
+
+If you're reading this, then pour yourself a tasty beverage. The history of this was so that I could learn the basics of websockets.
+
+Firstly, lets get the licensing out of the way...

+In all cases for scripts, replace all instances of 'YOURSERVER' with your server's domainname, ip, or some other identifier. To make your life easier, just grep for this.
+
+server_alienfeeds-pcap.js : This is the modified version of their map code to connect to the server.
+server.pl : This is the server that handles "clients". mainly the injectors and nodejs instances. It acts akin to an IRC messaging system.
+client-pcap-inject.pl : This is the perl script to sniff and inject messages. Change the MTU and network interface to your suiting.
+client-pcapcolors-inject.pl : Pretty much the same as above, but *attempts* to add colors to the dots on the map.
+client-syslogpipe-injext.pl : This is the perl script to crudely parse IP info out of a syslog pipe provided by syslog-ng. Can be modified to read any syslog file.
