Yes, thanks, right there on the top of the my screen is the old
evancz/elm-html. I should have paid more attention. Okay, found
elm-lang/elm-html. I knew it moved...going to have to stop using Google as
my entry into the documentation, as it will take the search giant a while
to make the top search result for "elm html package" to STOP pointing
to http://package.elm-lang.org/packages/evancz/elm-html/4.0.2/ and instead
go to http://package.elm-lang.org/packages/elm-lang/html/1.0.0/Html.
My bad, thanks again.
