dir ="path/to/files"
Dir.new(dir).entries.each { |e| 
  dirname = e.split(".")
  puts "wget -nd -k -r -P#{dirname[0]} http://localhost/path/to/dirs/#{e}"
}

output can be run as a shell script.  should be able to refactor this as a piped wget, i think

list directory and create wget calls to build standalone html dirs

Bash, html, links, images

Ruby
