module Util
# This module provides a `safe_puts` method which outputs to
# the given IO object, and rescues any broken pipe errors and
# ignores them. This is useful in cases where you're outputting
# to stdout, for example, and the stdout is closed, but you want to
# keep running.
module SafePuts
# Uses `puts` on the given IO object and safely ignores any
# Errno::EPIPE.
#
# @param [String] message Message to output.
# @param [Hash] opts Options hash.
