brian,

Thank you for using rvm. I hope that it makes your work easier and more enjoyable.
If you have any questions, issues and/or ideas for improvement please hop in #rvm on irc.freenode.net and let me know.
My irc nickname is 'wayneeseguin' and I hang out from ~09:00-17:00EST and again from ~21:00EST-~00:00EST.
If I do not respond right away, please hang around after asking your question, I will respond as soon as I am back.
Be sure to get head often as rvm development happens fast, you can do this by typing 'rvm update --head'.
  w⦿‿⦿t!

Upgrade Notes

  * 'rvm notes' tells you OS dependency packages for installing rubies.
  * If you encounter any issues with a ruby your best bet is to 'rvm remove X ; rvm install X' 
  * 1.8.7 default patchlevel is p174, override ~/.rvm/config/db in ~/.rvm/config/user
  * Gemset separator is '@' and will remain unless any rubies error using it.


Upgrade of RVM in /home/brian/.rvm/ is complete.
