i think this should do it...
def convert_from_textile_to_s5(fin)
File.read('fin').scan(/h1\..[^\n]*\n(?:\*[^\n]*\n)*/m).map{|s| RedCloth.new(s).to_html}
end

Looks like Pandoc is a solution for the problem, but I'd still like to know how to efficiently do this in Ruby... http://johnmacfarlane.net/pandoc/#downloads
I'd like to take a bunch of textile and turn it into an s5 file.
I was trying to use rubular to isolate blocks of text, but couldn't get just the seperate blocks isolated... Went to looping and ended up with this monstrosity.
There has to be a better way.
example regex trial over at http://www.rubular.com/regexes/4983
closer, but eliminate any more special characters and you get chaos

Remember - the point is to output s5, not just redcloth html. each "h1." block needs to be surrounded by a <div class="slide">redcloth html</div> Then we can drop our text into an s5 html file and voila!! http://meyerweb.com/eric/tools/s5/primer.html
