Bad link finder
Crawls a mirrored site and checks that all links either return a successful response or redirect to somewhere that does.
Set environment variables:
MIRROR_DIR, to the location of your mirrored site. Local files will be read in alphabetical order.
REPORT_OUTPUT_FILE, to the location you'd like the CSV saved to.
SITE_HOST, to the full host of the live site you'd like to test against, including protocol. For example,
START_FROM, optional, specify a file on disk from which to start, e.g.
example-folder/example.html. Will check this file and all following files. Useful for restarting aborted runs.
