You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: run.rb
    path of file: ./repos/jruby/bench/mri
    
    the code of the file until where you have to start completion: #
# Ruby benchmark driver
#

require 'benchmark'
require 'rbconfig'

$matzrubyonly = false
$rubyonly = false

$results  = []

# prepare 'wc.input'
def prepare_wc_input
  wcinput = File.join(Fil
    
def prepare_wc_input
  wcinput = File.join(File.dirname($0), 'wc.input')
  wcbase  = File.join(File.dirname($0), 'wc.input.base')
  unless FileTest.exist?(wcinput)
    data = File.read(wcbase)
    13.times{
      data << data
    }
    open(wcinput, 'w'){|f| f.write data}
  end
