Register an ‘at_exit` hook that runs the suite when the process exits.

@note This is not generally needed. The ‘rspec` command takes care

of running examples for you without involving an `at_exit`
hook. This is only needed if you are running specs using
the `ruby` command, and even then, the normal way to invoke
this is by requiring `rspec/autorun`.
# File rspec-core/lib/rspec/core/runner.rb, line 16
def self.autorun
  if autorun_disabled?
    RSpec.deprecate("Requiring `rspec/autorun` when running RSpec via the `rspec` command")
    return
  elsif installed_at_exit? || running_in_drb?
    return
  end

  at_exit { perform_at_exit }
  @installed_at_exit = true

    $stderr.puts(

end

def self.perform_at_exit
  # Don't bother running any specs and just let the program terminate
  # if we got here due to an unrescued exception (anything other than
  # SystemExit, which is raised when somebody calls Kernel#exit).
  return unless $!.nil? || $!.is_a?(SystemExit)

  # We got here because either the end of the program was reached or
  # somebody called Kernel#exit. Run the specs and then override any
  # existing exit status with RSpec's exit status if any specs failed.
  invoke
end

Run a suite of RSpec examples. Does not exit.

This is used internally by RSpec to run a suite, but is available for use by any other automation tool.

If you want to run this multiple times in the same process, and you want files like ‘spec_helper.rb` to be reloaded, be sure to load `load` instead of `require`.
