A makefile isn't a workaround. It's a place to implement more flexibility.

gEDA is superior to those tools: it does not take away your flexibility 
the way they do. It even plays nicely with tools that aren't designed to 
play nicely.

Agreed. But you if you thing gEDA is restricted to generating flat 
netlists, you don't understand it. You can't improve what you don't 
understand.

You're wrong. Haven't you studied spice-sdb?
