I could do this, but there is a snag: The -I flag is really meant to control the behavior of .model and .subckt cards. By default the contents of a .model or .subckt file gets dumped into the main SPICE deck *unless* you specify the -I flag. As a correlary, it will also control the behavior of the ".include" symbol. Therefore, I don't want to invert the logic of the -I flag without more thought since it impacts the behavior of things beyond the .include symbol. The problem is that ".include" is both a SPICE statement (command), and a gschem symbol. It is one of the only SPICE commands which also has a gschem symbol; most other SPICE commands are entered exclusively by manually sticking them into a SPICE-directive symbol. Since users see the .include symbol in the SPICE symbols lib, they assume that it generates a .include statement, but it instead embedds the named file. I probably exascerbated this by labeling the symbol ".include", when I really meant "embedd external file". Moving forward, here is another suggestion: 3. Borrowing a riff from you, Peter, I could make the default behavior of the .include symbol to just write out the string ".include foo.bar". Then I can add a gnetlist flag, say -e, which will force all .include symbols to embedd the external file into the SPICE deck. This creates the desired effect (i.e. stick a ".include foo.bar" into the netlist by default) while not messing around with spice-sdb's behavior with .model and .subckt cards. What do you think?
