[bug#73488] [PATCH 0/7] Add Jolly Good and some of its emulators

[Maxim Cournoyer]

This series adds the Jolly Good emulator API and reference user
interface (jgrf), and some core files (emulator plugins made to be used by
it). Currently I've packaged and tested their bsnes, nestopia and cega ports.


Maxim Cournoyer (7):
  gnu: bsnes: Remove input labels and use gexps.
  gnu: Add jg-api.
  gnu: Add jgrf.
  gnu: jgrf: Add search path mechanism.
  gnu: Add jg-bsnes.
  gnu: Add jg-nestopia.
  gnu: Add jg-cega.

I think we should write out "G-Expressions".  For the header, since we
do both style improvements, I'd just write "Use new package style",
though that one's a bit more controversial ;)

Content-wise LGTM.

I think both are acceptable; just like we can write sexps for
S-Expressions, gexps for G-Expressions seems to the point (and requires
less typing).

Yeah. That may not age too well if/when we have yet a newer package
style, haha!

Thanks for taking a look.
