# = Earth Distance Railtie
#
# Creates a new railtie for 2 reasons:
#
# * Initialize ActiveRecord properly
# * Add earthdistance:setup generator
class EarthDistance < Rails::Railtie
  # Creates the earthdistance:setup generator. This generator creates a migration that
  # adds earthdistance support for your database. If fact, it's just the sql from the
  # contrib inside a migration. But it' s handy, isn't it?
  #
  # To use your generator, simply run it in your project:
  #
  #   rails g earthdistance:setup
  class Setup < Rails::Generators::Base
    include Rails::Generators::Migration
