"""
This script was originally based on
https://github.com/atiumcache/pure-recipe
but has been modified to remove functionality
that I consider extraneous.
What remains is only a basic wrapper for recipe_scrapers,
but out of an abundance of caution
I'm including pure-recipe's original license below.
