# return_skeleton_generator.py takes JSON output from a module and
# and creates a starting point for the RETURNS section of a module.
# This can be provided as stdin or a file argument
#
# The easiest way to obtain the JSON output is to use hacking/test-module
#
# You will likely want to adjust this to remove sensitive data or
# ensure the `returns` value is correct, and to write a useful description
