Purpose built to grab a Blade Runner thread before IMDB yanks the forum feature, as requested here.
YMMV.
A little janky. Sorry.
From the repo root:
python -m grabber <url to forum thread> -j -o <path/to/output_dir>
For example:
python -m grabber http://www.imdb.com/title/tt0083658/board/thread/117969472 -j -o ~/Desktop/imdb_output/
Again: YMMV. Not tested anywhere but OS X. Mobile links should work.
