extracting posterior variances of random effects (lme vs. lmer)

List, 

I am having trouble locating documentation on how one extracts posterior 
variances of the random effects from an lme object.  I have found equivalent 
documentation for lmer(using ranef()), but nothing for lme.  Any help would be 
greatly appreciated!

Sam
