I do not need to generate a verilog netlist, they are already in
verilog, I need to combine circuits from differnt sources for the final
design and as gnetlist doesn't read verilog I need to get everything
into gscheme format. This is basically the path:

Circuit elements are coming from different sources, software, etc. The
common format we can all use is verilog so we are using that and use
icarus verilog for logic simulation. If we can get the verilog into
gscheme format files I can use gscheme to combine the blocks at the top
level (which also gives us a nice top level drawing) and run the design
through gnetlist to create a bdnet format netllist (I've got the
gnetlist backend mostly working to generate the bdnet format netlist).

I don't care what the schematics of the files created from the verilog
files looks like, I can create symbols for the top level and we never
need to decend into them. I do have a library of symbols for the
standard cells that will be used in the verilog files and can generate
flat verilog files so I was hoping someone had or had started a script
that can read in a flat verilog file, refer to a directory of symbols to
reference pin locations and create a gscheme file that is correct from a
netlist perspective. I could try to write this but am a h/w guy and only
fair at s/w (which is real obvious when you look at my gnetlist bdnet
backend).
