I'm trying to find out how to update the GNU web site.  So far there's a
lot of discussion but no conclusions.

To build the HTML version, type "make html".  You will need to have the
texi2html package installed.

Info format, that comes pre-built with GNU make, is FAR better than HTML
format anyway, though.

Sorry, I still don't understand what you want to do.  Please provide a
more realistic example using actual filenames and describing the way you
want make to behave when it sees them.
