Selenium, Rspec in ruby. Start selenium server in code

I got it to work in ruby, but I have to start the selenium servver
manualy before I runn the program. That is unesesary mutch work and
complicated. Is there a way to start the selenium server inside the code
and stop it at the end?

Here is a code example i got to work… it is a bit messy

require 'rubygems'

gem ‘thoughtbot-shoulda’
require ‘shoulda’

require ‘spec’
require ‘spec/story’

require ‘test/unit’
require “rubygems”
gem “selenium-client”, “>=1.2.15”
require “selenium/client”
require “selenium”

describe "test" do

  before :all do
    @browser = Selenium::Client::Driver.new \
      :host => "localhost",
      :port => 4444,
      :browser => "*firefox",
      :url => "http://www.google.com",
      :timeout_in_second => 60
  end
  after :all do
    @browser.close_current_browser_session
  end


  it "test1" do
    @browser.start_new_browser_session
    @browser.open "/"
    @browser.type "q", "Selenium seleniumhq.org"
    @browser.click "btnG", :wait_for => :page
    assert @browser.text?("seleniumhq.org")
  end
end

What do I need to add to get it to start the selenium server automaticly
and stop it at the end?
