Could someone please explain what this "dbl" mode is supposed to do and how it works. The instructions in the dbl.el file don't say enough, and I can't make sense of what happens if I start it up. Is it supposed to be able to step through Lisp code, somehow? Why does it shart up a shell? When it asks for a program on startup, what program is that? The Lisp system? Some Lisp source file? Yours in confusion, JD
