So you want to add stuff to the beginning of a file? Well, as far as I 
know, you can't just add stuff to the beginning, you have to create a 
new file, add your stuff, then append the old stuff at the end of the 
new file.

new_file = File.new("your_new_file.txt", "w+")

new_file.write("I'm at the beginning\n")

IO.readlines("your_old_file.txt").each do |line|
  new_file.write(line)
end

new_file.close
