// tell express to use the bodyParser middleware                                                 
// and set upload directory                                                                      
app.use(express.bodyParser({ keepExtensions: true, uploadDir: "uploads" }));                     
app.engine('jade', require('jade').__express);                                                   

app.post("/upload", function (request, response) {                                               
    // request.files will contain the uploaded file(s),                                          
    // keyed by the input name (in this case, "file")                                            

    // show the uploaded file name                                                               
    console.log("file name", request.files.file.name);                                           
    console.log("file path", request.files.file.path);                                           

    response.end("upload complete");

// render file upload form                                                                       
app.get("/", function (request, response) {                                                      
    response.render("upload_form.jade");
