def do_configuration(args)
  Gem.configuration = @config_file_class.new(args)
  Gem.use_paths Gem.configuration[:gemhome], Gem.configuration[:gempath]
  Gem::Command.extra_args = Gem.configuration[:gem]
end

validate_encoding (args)

def validate_encoding(args)
  invalid_arg = args.find {|arg| !arg.valid_encoding? }

  if invalid_arg
