R help - Sep 2009 - define a new family (and a new link function) for gam in gam package

Dear R list,

is it possible to define a new family (and a new link function) for gam 
in gam package? How?

I read the help for gam, family, gam.model, make.link but I did not find 
a solution.

Regards

Wood provides an example for negbin with alternate links in package  
mgcv;

library(mgcv)
?negbin
negbin  # produces the code

Dear David,

I am using gam in gam package (not in mgcv) .... it is possible to force gam 
in mgcv to behave like gam in gam package?
