Warning: the disk image will be deleted in the process. Make a copy!
1) Run main on an macOS install image (iso or dmg or pkg) which combines the following two steps:
a) `iso-deep-unpack` extracts all package-like formats and repeats the process for all nested packages.
b) `rsrc-to-icns.py` will find all `.icns` files inside Resource Forks and extract them inplace. See Resource Fork disclaimer in [collection-extracted/README.md](/icns-analysis/collection-extracted/).
analyze.py will create (or update) the extracted.db database (see results) and then run an automated evaluation on it.
