I think we should support the manuals on gnu.org, but the problem is
it's hard to do that without an explicit list of all of them, and that
list will then have to be continuously maintained to keep it
up-to-date.

So maybe just support all of the manuals that come with Emacs, and
provide a defcustom for users to extend the list by specifying
associations of the form (MANUAL-NAME . URL) ?

We don't begin our symbols with a slash.

This is not our style of nesting parentheses.

I think if we need to follow Texinfo, we should have here a more
specific pointer to where this encoding by Texinfo is documented.

Thanks.
