R help - Aug 2010 - confidence Intervals for predictions in GLS

Hi everyone:

Is there a function in R to calculate the confidence intervals for the  
predictions of a GLS(Generalized Least Square) model?

The function "predict" gives confidence intervals for the predictions
of other types of models (lm, glm, etc) but not gls.

Any input will be much appreciated,

Best,

Camilo
