[Magic-dev] GDS output

I brought a gds file containing 7 layers into magic
that was provided by a customer.  I did this by
creating a technology file using the script to produce
gdstemp.tech.  I added a new layer (layer 1) to the
technology file.  Now I am trying to output a gds
file, but by using 'gds write' I only get a gds file
with the original 7 layers, not my new layer (which is
the only layer I really need in the file).  How can I
get my new layer to output?  The .tech file is below.
