Include a postscript source file into Troff

[Stephen McIntosh]

Does anyone know of the command to include a postscript file into a troff
document.

I have tried the following command, but an error has occurred

	\X'code@/tmp/1' 

		where /tmp/1 is postscript source

	the following error occurs using the command: troff -mm troff_filesource

         	Unknown device control 'X'

Has anyone got any alternatives..

Thanks in Advance
