#   Application template generated by the rails_apps_composer gem.
#   Restrain your impulse to make changes to this file; instead,
#   make changes to the recipes in the rails_apps_composer gem.
#
#   For more information, see:
#   https://github.com/RailsApps/rails_apps_composer/
#
#   Thank you to Michael Bleigh for leading the way with the RailsWizard gem.

#   Primarily generated by file:
