ARIMA model with seasonality

Hello:

I have a series of monthly data which alos has seasonality, and I was
trying to model it as a seasonal ARIMA model. I wasnt sure how to use
arima function in R to model a seasonal time series (in fact my
knowledge of ARMA model is quite rudimentary). Can someone help me in
this regard, or can point me to some example code or other R resources?
Another question: how far the forecasts from such a model make sense??

thanks
Swaroop
