And a backtrace:

Consulting the EWW manual, I see nothing about configuring Emacs to
enable it to use `eww'.  I see only this cryptic statement:

  However a GNU Emacs with `libxml2' support is required.

Could that be the problem?  What does that even mean?  How does a
user tell whether `libxml2' support has been provided?  If it has
not, how does a user obtain it?  Etc. etc.

Non-geek Emacs users are likely to want to try using Emacs to browse
the web.  Unfortunately, they seem to have been hung out to dry.

The Emacs manual, node `EWW', says this:

  You can use EWW as the web browser for
  `browse-url', *note Browse-URL::.  For full details, *note EWW:
  (eww)Top.

However, unlike `eww', `browse-url' works fine, out of the box.
And I see no "full details" about using `eww' with `browse-url' in
the EWW manual.  In fact, "browse-url" does not even occur in the
EWW manual.
