module Cachetastic # :nodoc:
# This class handles logging for the caches and their adapters.
# This class exists simply to supply the ability to write to
# multiple loggers simultaneously from a single call. It also
# creates a standardized message to write to those loggers.
#
# It is important that any logger type of class you decide to use
# reponds to the following methods:
# fatal(message)
# error(message)
# warn(message)
# info(message)
# debug(message)
class Logger
# An <tt>Array</tt> of 'real' loggers to write to.
attr_accessor :loggers
# The <tt>initialize</tt> method takes an <tt>Array</tt>
# of your favorite logger style classes to write to.
