• A CommonJS amd module which doesn't require _. This version will not have _ integration.
• A global-namespaced version that creates the GLOBAL.accessorize object. This version will look for a GLOBAL._ and use it if it exists to provide _ integration. It will also allow one to set accessorize._ if needed.
