I've really taken to the OpenSCAD grammar for building up 3D and 2D
objects, so I've decided to make a first cut at a python library that
allows one to do the same for creating PCB footprints. Its not
actually an OpenSCAD parser, but just a set of python functions made
to look like OpenSCAD.

small snippet:

silk(w=silk_w) & (
        square(courtyard, center=True) |

        translate([-courtyard[0] / D(2), -pitch * (n[1] - 1) / D(2)]) &
        left(silk_w * D(2)) &
        line([0, pitch * D(2)], center=True)
)

(a silk square is drawn and a small line representing pin 1)
