Thank you Jamie, hello Test Kitchen.
This is a first-pass renaming of the Jamie project to test-kitchen. The
following are major breaking changes:
*
*
*
*
*
*
all constant references of `Jamie` have been renamed to `Kitchen`
the .jamie.yml file has been renamed to .kitchen.yml
the binary bin/jamie has been renamed to bin/kitchen
the Rake task namespace :jamie is now :kitchen
the Thor task namespace :jamie is now :kitchen
the `kitchen new_plugin` subcommand will create a 'kitchen-*' gem
project
