How do you get this?  Is that by running the scripts in the admin/
directory, like make-manuals?  Those scripts are for generating
manuals we upload to the GNU Software Documentation site, they are not
for users to generate HTML docs.  For the latter purpose, you are
supposed to say

  $ cd doc/emacs && make emacs.html HTML_OPTS='--html --split=node'

It is part of the Emacs "webpages" repository, which you can browse
here:

  http://web.cvs.savannah.gnu.org/viewvc/emacs/emacs/

I don't see a need to include this in the Emacs Git repository.  The
stuff related to the Web documentation is maintained in a separate
repository for a reason.

The way these scripts are used is described in admin/make-tarball.txt.
You will see there that the produced HTML manuals are moved to the
separate webpages repository and sent upstream from there; the file
manual.css is part of that repository.  So there's no need to mix this
with the Emacs sources, because Emacs users are not supposed to
produce manuals in the format used for the GNU Documentation web site.
