# Exception notifier (rails3) only works as a rack middleware,
# but what if you need notifications inside a rake task or a script?
# This is a quick hack around that.
#
# Wrap your code inside an exception_notify block and you will be notified of exceptions
#
# exception_notify { clear_payments }
def exception_notify
  yield
rescue Exception => exception
