[Getdp] How to define Robin boundary conditions

Probably a simple question but I can't find the answer in the examples of
the wiki or searching the list.

I am trying to define a Robin type boundary condition for the Laplace
equation on a cube

dphi/dz+constant*phi=0 on one face

I think the weak form of this is
integral_over_face(test_function * trial_function*constant) =0

can someone point me to an example of how to write this in the .pro file?
thanks

and thanks to Christian for his public spiritedness over many years by the
look of the archives.
