Rubyのrequireをファイル名だけ書けばOKにする

requiree.rb

$ruby_file_list = `find -name "**.rb"`.split("\n")
def requiree(filename)
  result_list = $ruby_file_list.select {|line| line.include?(filename)}
  if result_list.length == 0 then
    throw "file not found: #{filename}", 1
  end
  require(result_list[0])
end
