	<p>
	If you are unable to install Ruby on Rails (e.g. because you do not have
	control over this server) then you could also <em>vendor</em> (bundle)
	your Rails version into your application by running <pre>rake vendor:rails</pre>
	in your application's source directory, and redeploying your application.
	Please search the Internet for "vendor rails" if you're not familiar with
	this technique.
