predict.coxph

Is there anywhere to find more detail on the different types of 
predictions ("lp", "risk", "terms") in predict.coxph?  I would like to 
create a summary risk score after fitting a multivariable model with 
time-varying covariates.  If it makes a difference, 0 will be a 
substantively meaningful value for all of the covariates considered.
