Feature: Usage with RSpec metadata VCR provides easy integration with RSpec using metadata. To set this up, call `configure_rspec_metadata!` in your `VCR.configure` block. Once you've done that, you can have an example group or example use VCR by passing `:vcr` as an additional argument after the description string. It will set the cassette name based on the example's full description. If you need to override the cassette name or options, you can pass a hash (`:vcr => { ... }`).
