A really quick and simple rails log file parser. I just made it because I was board one day and felt like trying 
something out.

  logfile = Railsfile::Parser.new("#{ENV['HOME']}/Desktop/02_production.log")
  requests = logfile.requests
  [requests[0], requests[100]].each do |r|
    %w[request processing controller action ip_address occurred_at request_method 
      completion_time requests_per_second rendering_time db_time status_code url].each do |m|
      puts r.send(m)
    end
    puts ''
  end
  
Someday will be something like:
