        // description of your code here
I wrote a nice description of this issue, but snippets ate it.  

In short, this parses complicated form names into nice hashes, i.e. name[asd][asd] for multipart forms.

module Camping
module Base
 def initialize(r, e, m) #:nodoc:
      e = H[e.to_hash]
      @status, @method, @env, @headers, @root = 200, m.downcase, e,
          {'Content-Type'=>'text/html'}, e.SCRIPT_NAME.sub(/\/$/,'')
      @k = C.kp(e.HTTP_COOKIE)
      qs = C.qs_parse(e.QUERY_STRING)
      @in = r
      todo = []
      if %r|\Amultipart/form-data.*boundary=\"?([^\";,]+)|n.match(e.CONTENT_TYPE)
        b = /(?:\r?\n|\A)#{Regexp::quote("--#$1")}(?:--)?\r$/
        until @in.eof?
          fh=H[]
          for l in @in
            case l
            when Z: break
            when /^Content-Disposition: form-data;/
              fh.u H[*$'.scan(/(?:\s(\w+)="([^"]+)")/).flatten]
            when /^Content-Type: (.+?)(\r$|\Z)/m
              puts "=> fh[type] = #$1"
              fh[:type] = $1
            end
          end
          fn=fh[:name]
          o=if fh[:filename]
            o=fh[:tempfile]=Tempfile.new(:C)
            o.binmode
          else
            fh=""
          end
          while l=@in.read(16384)
            if l=~b
              o<<$`.chomp
              @in.seek(-$'.size,IO::SEEK_CUR)
              break
            end
            o<< l
          end
          if(fn)
            qs.merge!(C.qs_parse(fn + "=1"))
            parts = fn.split(/\[/)
            line = ""
            parts.each do |pp|
              pp = pp.gsub(/\]/,"")
              line += "['#{pp}']"
            end
            #p "line is:"
            #p line
            #p fh
            todo << ["qs#{line}", fh]
            #eval("qs#{line} = fh")
            #p qs
          end
          fh[:tempfile].rewind if fh.is_a?H
        end
      elsif @method == "post"
        qs.merge!(C.qs_parse(@in.read))
      end
      #post process vars
      todo.each do |n|
        eval("#{n.first} = n.last")
      end
      #p "END QUERY"
      #p qs
      #exit
      @cookies, @input = @k.dup, qs.dup
    end


end 
end
