=46rom the ngspice manual:

"you may place a .TITLE <any title> line anywhere in your input deck. =
The first line of your input deck will be overridden by the contents of =
this line following the .TITLE statement.=E2=80=9D

This means that no special feature is required of a SPICE netlister =
here: all the gEDA SPICE netlisters have ways to insert arbitrary SPICE =
directives into the deck. I=E2=80=99m not a fan of adding special =
features that duplicate general capabilities.

> What bothers me is the usage of the "comment=3D" attribute:

I think that attributes specialized to a particular netlist format =
should use names unique to the format going forward. For spice-noqsi, =
there are spice-prolog=3D, spice-epilog=3D and spice-prototype=3D. =
Legacy attributes like file=3D are, of course, difficult to replace.
