    module Checks

      # This check reports classes with a Flog metric score that is higher than the threshold. The Flog metric is very similar to the cyclomatic complexity
      # measure but also takes Ruby specific statements into account. For example, calls to metaprogramming methods such as +define_method+ or
      # +class_eval+ are weighted higher than regular method calls.
      #
      # Excellent does not calculate the score exactly the same way as Flog does, so scores may vary. For Flog also see
      # http://github.com/seattlerb/flog.
