I'm not sure of the exact details, but I'd have thought you could do this
with libgeda and some scheme. I'm not sure if there is am existing shell
(the "gaf" program?), or whether you'd have to use some C boilerplate too.
gnetlist would also be an obvious host to try starting from.

Fwiw, this utility might already exist (or I might have wanted it at some
point - was some years ago now so I don't fully recall). It is useful in a
project manager program context (or general workflow automation), as a kind
of "make depend" generator.

What I suspect we don't currently have is a good way to track exactly back
to the source symbol file. You'll likely be able to discern embedded vs.
not, and symbol name. You'll then likely be able to find out more about the
symbol by querying the name in the symbol library code.... But as I say,
it's been many years since I last had my head deep in the internals of
libgeda.
