module FactoryGirl
  module Syntax

    # Extends ActiveRecord::Base to provide a make class method, which is an
    # alternate syntax for defining factories.
    #
    # Usage:
    #
    #   require 'factory_girl/syntax/blueprint'
    #
    #   User.blueprint do
    #     name  { 'Billy Bob'             }
    #     email { 'billy@bob.example.com' }
    #   end
    #
    #   FactoryGirl.create(:user, name: 'Johnny')
    #
    # This syntax was derived from Pete Yandell's machinist.
