/*
This script was originally created to iterate over all open
PRs to label and comment on specific PR errors (i.e. guide related
filename syntax and front-matter).

Since the first run which covered over 10,000+ PRs, it is currently
ran every couple of days for just the most recent PRs.

To run the script for a specific range (i.e. label and comment on
guide errors), run `node sweeper.js range startingPrNumber endingPrNumber`
