This discussion is getting a bit out of hand. I said some time ago:

There were some suggestions and some discussion, and then David Sibley
pointed out:

I don't. But the whole discussion is boiling down to a matter of
personal preferences. Since I live most of the time within emacs, and
maintain it here, it is perhaps natural that I have become addicted to
info. On the other hand, I will retract my complaints about lack of
"good online documentation" (I had no intention of putting down ? and
??), and qualify it instead as a "lack of an online manual of the
kind *I* find convenient".

Now, perhaps I would have kept to myself about info, if it wasn't for
the circunstance that a hypertext version of GAP documentation had been
created, for another plataform. The source code for GAP shows that
emacs was a heavily used tool for development; maybe the developers of
GAP would have something to say on this matter.

Anyway, it is not such a big deal.
