      This generator makes the following changes to your application:
       1. Generates blacklight:models
       2. Generates utilities for working with solr
       3. Creates a number of public assets, including images, stylesheets, and javascript
       4. Injects behavior into your user application_controller.rb
       5. Adds example configurations for dealing with MARC-like data
       6. Adds Blacklight routes to your ./config/routes.rb

      Thank you for Installing Blacklight.
