12 : : * Command-line options can override these settings during argument parsing
13 : : *
14 : : * The function clears the shared `Config` object and then assigns explicit

16 : : * by libmem is prepared as string descriptors or descriptor arrays: `db_primary_file_path`,
17 : : * `db_file_name`, `roots`, and `db_file_paths`
18 : : *
19 : : * Normal scan roots are collected later in `config->roots`, while `--compare`
20 : : * database arguments are collected in `config->db_file_paths`
