How can I get coordinates file with components in PCB?

 I am a geda user and I got a problem during using geda.
 I already finished the PCB board design, then I want to give the board and components to SMT factory. But the SMT factory said
 they need a coordinates file with components on the board. I don't know how to created coordinates file.
 I checked "Export Layout"meau, only bom, gcode, greber, nelma, png, ps and eps. So how can I get coordinates file with PCB??
