I think what happened is that David A., the main PG developer, had a
conversion similar to yours (but in his case to eclipse rather than jedit).

I hope the "today" is not literal, but soon, Yes.  I am here to help.

By "classic" do you mean "TTY"?  So if the new work is successful PG
lives on?  Deal.  I have a reservation, though: will this fundamentally
change the feel of Isabelle/PG?  For instance, will it now start working
magically in the background instead of synchronously?

Now to return to my immediate problem, after I register the PG
component, do I still need the "emacs" script?  I think this might be
the case from reading the other thread.  If yes this would be a handy
bit of information to put in the NEWS file.
