+= Browser
+
+Do some browser detection with Ruby. Includes ActionController integration.
+
+== Installation
+
+  gem install browser
+
+== Usage
+
+  require "rubygems"
+  require "browser"
+
+  browser = Browser.new(:ua => "some string", :accept_language => "en-us")
+  browser.safari?
+  browser.opera?
+  browser.mobile?
+  browser.firefox?
+  browser.ie?
+  browser.ie6?        # this goes up to 9
+  browser.capable?    # supports some CSS 3
+  browser.platform    # return :mac, :windows, :linux or :other
+  browser.mac?
+  browser.windows?
+  browser.linux?
+  browser.meta        # an array with several attributes
+  browser.to_s        # the meta info joined by space
+
+See the tests for more examples.
+
+=== Rails integration
+
+Just add it to the Gemfile or `environment.rb`, depending of your Rails version.
+
+  gem "browser"         #=> Rails 3
+  config.gem "browser"  #=> Rails 2
+
+This adds a helper method called `browser`, that inspects your current user agent.
+
+  <% if browser.ie6? %>
+    <p class="disclaimer">Your're running an older IE version. Please update it!</p>
+  <% end %>
