module Output
# Create a new output based on the environment.
#
# The environment variable `CONSOLE_OUTPUT` can be used to specify a list of output classes to wrap around the output. If not specified the {Default} output is used.
#
# The output argument is deliberately unders-specified but can be an IO object or an instance of {Output}.
#
# @parameter output [Console::Output] The output to wrap OR an IO object.
# @parameter env [Hash] The environment to read configuration from.
# @parameter options [Hash] Additional options to customize the output.
# @returns [Console::Output] The output instance.
