Twittering with Arduino+Ethernet Shield

Sorry, here is the code:

#include <SPI.h> // needed in Arduino 0019 or later
#include <Ethernet.h>
#include <Twitter.h>

// Ethernet Shield Settings
byte mac[] = { 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX };

// If you don't specify the IP address, DHCP is used(only in Arduino 1.0 or later).
byte ip[] = { xx, xx, xx, xx };

// Your Token to Tweet (get it from http://arduino-tweet.appspot.com/)
Twitter twitter("XXXXXXXXXXXXXXXXXX");

// Message to post
char msg[] = "Hello, World! I'm Arduino!";

void setup()
{
delay(1000);
Ethernet.begin(mac, ip);
// or you can use DHCP for autoomatic IP address configuration.
// Ethernet.begin(mac);
Serial.begin(9600);

Serial.println("connecting ...");
if (twitter.post(msg)) {
// Specify &Serial to output received response to Serial.
// If no output is required, you can just omit the argument, e.g.
// int status = twitter.wait();
int status = twitter.wait();

if (status == 200) {
Serial.println("OK.");
} else {
Serial.print("failed : code ");
Serial.println(status);
}

} else {
Serial.println("connection failed.");
}
}

void loop()
{
}
