Re: gEDA-dev: Broken slotting

[Steve Meier <smeier-at-NOSPAMalchemyresearch_dot_com>]

I have been violating the rule "All pins must have a pinseq=# attribute
attached to the pin object. " regularily. I reason, that if a device has
only one gate then no slot list is needed. Now I wonder if the slot list
is needed for spice?

Thanks,
