How about doing it for gnucap?
Lots of people have written front-ends and wrappers for Spice.
Gnucap really needs something like that, and to provide the
functionality of "nutmeg".

Spice: no (to all). Spice is designed to load a circuit once,
then make only non-structural changes. For a serious topology
change, you need to start over.
Gnucap: yes (to all). It is designed so you can make arbitrary
changes to the circuit. It can even make some topology changes
dynamically as the simulation runs.

I think it is letters, numbers, and underscore. Mostly not case
sensitive. Actually, the rule is that it is not case
sensitive, but there are occasional surprises, like the FAT
file system. Model names are supposed to start with a letter,
but there are occasions where this is not enforced.
