As odd as this sounds, you can't do what you want right now.  The
attributes for SPICE netlisting like "model", "file-name", and the like,
are not promoted from the symbol.  That means that if you embedd them
into the .sym file, they won't show up in the .sch file & you won't
get them into the netlist.  

I understand that Ales is working on changing this.  Meanwhile, use
gattrib to quickly set up and change your SPICE attribs after you draw
your schematic.
