I am not surprised. The DC part is ok. I had a lot of trouble
with the dynamic part. This experience was a big factor in
convincing me that the model strategy needed to change. I
don't want to port models. Gnucap needs to be able to use
models developed by others with no changes.
In the future there will be no built-in models. That's what
plugins are for.
