require 'delegate'

# A delegator that allows the size method to be used on the STDOUT object.
#
# The size of the content written to STDOUT cannot be measured normally. This
# class wraps the STDOUT object so the cumulative size of the content passed to
# the write method (while wrapped in this decorator) can be measured.
