arima time series in R

Hi

Could just anyone explain me the coefficients in the output of arima model
The person who wrote the help page already did, but that is hardly 'just 
anyone'.
timeseriesarima <- arima(series, order=c(1,1,2))
timeseriesarima
Series: series
ARIMA(1,1,2)

Coefficients:
          ar1      ma1     ma2
       0.9744  -1.7695  0.7873
s.e.  0.0310   0.0481  0.0426

sigma^2 estimated as 337.4:  log likelihood=-1096.03
AIC=2200.07   AICc=2200.23   BIC=2214.2
That is not from arima in package stats, so you need to follow the 
posting guide to tell us whose wrapper it is and hence which help page 
to read.  (Possibly package TSA.)
