[R] svyglm fit method?

[Corey Sparks]

Dear list,
I am using svyglm in the survey library to fit a binomial logistic  
regression accounting for sample design.  The documentation says the  
models are not fit by maximum likelihood, so my question is what is  
the fitting method?  Pseudo likelihood?  Generalized least squares?   
Thanks for any insight.
Best,
Corey
