Function extract_pkg_files

fn extract_pkg_files(
    pkg: &DirEntry,
    target_dir: &Path,
    repo_name: &str,
) -> Result<()>

Use tar to extract relevant package metadata and script files from packages files.

This function attempts to extract “.MTREE”, “.BUILDINFO”, “.PKGINFO” and “.INSTALL” files. Extracted files are placed in a directory structure that reflects the package’s association with a package repository.

Note

Since some files are optional, we have to take a look at the files in that tarball to determine which of the files need to be actually extracted.
