title: install RVM offline completely
body: <p>I am planning to create an installer for a ruby script but I want to be able to ensure that the machine has RVM installed. Is there a way to install RVM completely offline and unobtrusive as well(by unobtrusive, as in create a script that can do everything instead of ask users to add something to their bash_profile or bashrc)</p>
  
  <p>I am not asking for the script itself, just a quick pointer as to how to go about this route(if it is even possible). We have also looked into this question which was helpful enough:</p>
  
  <p><a href="https://stackoverflow.com/questions/5447805/rvm-is-there-a-way-for-simple-offline-install">RVM - is there a way for simple offline install?</a></p>
  
  <p>but a bit misleading as the answer only shows us how to install a ruby in RVM offline. We need to be able to install RVM itself offline, and looking at the script </p>

  <p>do I just include this whole script and change the rvm_releases_url into something else? And is it safe to just append the rvm path to a user's bash_profile, or bashrc instead of asking them to do it?</p>
