[Gmsh] Variable thickness surface

I am using gmsh for modelling 2D components and I am trying to find out how
I can set a thickness to the plate/shell elements. First I was thinking
about assigning regions of different thicknesses to different physical
groups but by this approach I can specify only a constant value which is
not what I need.
According to this conversation from the mailing list it should be possible.

I checked the tutorial 7 he referred to. In my opionion this examples
controls the size of the elements by using a *.pos file and not controlling
the thickness. So my question is how I can assign a thickness for example
to a rectangle area as a linear function from 1 to 10 in x-direction and
constant in y-direction?
