You can include the module, but keep reading below....

  require 'cgi'
  include CGI::Html3
  cgi = CGI.new("html3")
  puts html { h1 { "hi" } }

For reasons I haven't fully looked into, this doesn't print the
DOCTYPE declaration; it just prints:

  <HTML><H1>hi</H1></HTML>

so it's probably treading where it shouldn't.  But maybe it could
point you in the right direction (if there is one :-)
