Essentially, if you would normally have run something like rspec spec/my_spec.rb, and you want to use the gems specified in the Gemfile (5) and installed via bundle install (1), you should run bundle exec rspec spec/my_spec.rb.

Similarly, is there a shortcut to run bundle exec? Binstubs are a shortcut-or alternative- to always using bundle exec.

For example, if you run bundle binstubs rspec-core, Bundler will create the file bin/rspec.
In this manner, what's the difference between bundler and a binstub?
