Code required for recurrence relations

Hi all

I am running v. 6.03 and would like to know if anyone is aware of any code 
(or has a function) that will perform the following task

Take a generating function, such as 2*x/(1-x)^2, and use it to extract the 
recurrence relation from whence it came - in this case it just generates the 
even numbers

So the function will be something like f[2*x/(1-x)^2,u,n] and would output 
something like u[n]->u[n-1]+2

Many thanks

Ant
