# You can use arbitrary logger which responds to #debug, #info, #error and #fatal methods, so for example the logger from standard library will work fine:
#
# AMQ::Client.logging = true
# AMQ::Client.logger = MyLogger.new(STDERR)
#
# AMQ::Client.logger defaults to a new instance of Ruby stdlib logger.
#
# If you want to be able to log messages just from specified classes or even instances, just make the instance respond to #logging and set it to desired value. So for example <tt>Queue.class_eval { def logging; true; end }</tt> will turn on logging for the whole Queue class whereas <tt>queue = Queue.new; def queue.logging; false; end</tt> will disable logging for given Queue instance.
