Some test with Node.js

Node Logger

  var sys = require('sys')

  var tail = process.createChildProcess("tail", ["-f", filename]);
  sys.puts("listening to file " + filename);

  var http = require("http");
  http.createServer(function(req,res){

    res.sendHeader(200,{"Content-Type": "text/plain"});
    res.sendBody("As soon as the log rotates, you'll see it here\n");    
    
    tail.addListener("output", function (data) {

    });
