Sample of my old custom stats file that adds spec_no_rails

my stats

if ENV['LOAD_RAILS'] == '1'
  task :stats => "ma:add_no_rails_dirs_to_stats"
  namespace :ma do
    desc "Report code statistics (KLOCs, etc) from the application"
    task :add_no_rails_dirs_to_stats do
      require 'rails/code_statistics'
      ::STATS_DIRECTORIES << %w(NoRails\ Lib\ specs spec_no_rails/lib) if File.exist?('spec_no_rails/lib')
      ::CodeStatistics::TEST_TYPES << "NoRails Lib specs" if File.exist?('spec_no_rails/lib')

      ::STATS_DIRECTORIES << %w(NoRails\ Model\ specs spec_no_rails/model) if File.exist?('spec_no_rails/model')
      ::CodeStatistics::TEST_TYPES << "NoRails Model specs" if File.exist?('spec_no_rails/model')
    end
  end
end

This is back when I was putting my code in lib/app_name. I put it in app/app_name now, so you can alter this, if you like.
