I have numerous gems that I use across all Rails projects, but that aren't part of the projects' Gems, for example powder for managing POW.
It would make sense to me to manage these with a global Gemfile, but I can't see any examples of this.
How should I manage global Gems that I don't want in my project gemfiles? It would be good to have a single point of install for when I set up a new machine etc.
I'm using chruby alongside ruby-install to manage my Ruby versions.
