A socket server that listens on a host/port for connections and suggests tags for the incoming text
badtagger.js <port> <host>
This utility is provided as an example of using an external task that doesn't have any prior knowledge of
TiddlyWiki. Like many Unix utilities, it just reads and writes to a socket.
