Feature Request: Recursively open archives

[ivmeta]

Hello there!

Would it possible to have Scalibr recursively open (with a depth limit, to avoid pathological cases) archives (we're thinking python's subpar .par files, .rpms, .deb, .zip, tarballs, etc).

Ideally we're looking to extract executable binaries from it too.

Thanks!

Are you thinking of generic support for archive traversal in SCALIBR or extractor-specific logic for finding zipped files? e.g. for .jar files we do traverse the archive to find sub-packages. It'd definitely make sense to do something similar for .deb, .par, etc.

For .zip and tarballs I assume you'd be looking for any kind of package descriptor in them? So that wouldn't be extractor-specific behavior. While not all integrations might want to enable this it'd definitely make sense for SCALIBR support this if we also add a flag to enable/disable the feature.
