Easily export X,Y placement data for automated PCB assembly within EAGLE.
The "Screaming Circuits" ULP that ships with EAGLE is in inches. What if you want mils or mm? What if you want to deliberately ignore parts marked as DNP?
Simply run export_centroid_mils.ulp or export_centroid_mm.ulp. To mark a part as NOPOP, create an attribute with name "BOM_DNP" and value "DNP". The export ULP will ignore it when creating the placement file.
