//          ROD Mezzanine  Silk Only  Geometry
//         ------------------------------------
//
//   The purpose of this  Silk Only  FPGA Mezzanine  geometry
//   is to reserve space on the HTM Module layout for the FPGA
//   Mezzanine card   and
//
//   this geometry provides the real mounting screw holes for
//   the standoffs that support the FPGA Mezzanine.
//
//   - Recall that the  FPGA Mezz  is  85.0 mm in  by  85.0 mm.
//
//   - I will make the  0,0  of this geometry in its Center.
//
//   - This geometry has a minimal Component Outline in its Center.
//
//   - This geom has pins for only the 4 mounting screw holes.
//
//   - For now these mounting screw holes are for M2.5 screws.
//
//   - This component has the  Not in BOM  attribute.
//
//   - This component is used with 3 of the Samtec connectors
//     in a  Relatively Positioned Component Set  to make the
//     overall footprint for the FPGA Mezzanine card.
