rvmrc file that controls the version of Ruby, the Gemset, Rubygems, and Bundler. Use this if you want to control this stuff in your development workflow.

.rvmrc

# Bare minimum Gems that are needed to keep a Ruby development environment in sync. This assumes
# that you use bundler in your workflow to control the installation of all other gems. If you need
# to bump the bundler or rubygem version across your team, change that here, then run bundler and
# and keep going.
