I'm tired of the complications that tools like bundler and rvm inject into my system and my workflow. I don't want 4 billion gems installed globally. I don't want to have `rake` slow down for no good reason. I don't want rvm to regress on undefined variables over and over and over (and I don't want to report it anymore when it does). I want as much simplicity as I can afford and still be able to get my job done. I've found pretty good balance using rbenv (only when needed) and by using this 45 line shell function `ohmygems` (aliased to `omg`, of course). I still have my system-level gems as my previous GEM_HOME gets moved into GEM_PATH so things like minitest and autotest are always available. But now I have private gems that are incredibly easy to switch around and only rely on simple environment variables to manage. To go back to normal, simply run `omg reset`.
