Ember CLI Legacy Blueprints

The `ember-cli-legacy-blueprints` package (version 0.2.1) is an Ember CLI addon developed to provide backward compatibility for older Ember CLI projects (specifically those targeting Ember CLI 2.0.0 or later) that continue to manage Ember and Ember Data dependencies using Bower.js. It reintroduces a comprehensive set of standard blueprints—such as `component`, `controller`, `route`, `model`, `service`, `adapter`, `serializer`, and `acceptance-test`—which, in contemporary Ember CLI configurations, are bundled directly with their respective library addons (e.g., `ember-source`, `ember-data`, `ember-cli-qunit`). This addon is exclusively relevant for legacy applications that have not yet transitioned their core dependencies from Bower to npm. Its primary function is to ensure that `ember generate` commands operate correctly in these aged environments, thereby preventing errors associated with missing blueprint definitions when utilizing outdated dependency management practices. New Ember projects or those that have successfully migrated their core dependencies to npm should neither require nor install this package.
