Validation report will be written to `<asset_filename>.report.json`.
If <input> is a directory, validation reports will be recursively created for each *.gltf or *.glb asset.

Validation log will be printed to stderr.

Shell return code will be non-zero if at least one error was found.

-p, --[no-]absolute-path         Write absolute asset path to the validation report.
-m, --[no-]messages              Print issue messages to stderr. Otherwise, only total number of issues will be printed.
-a, --[no-]all                   Print all issue messages to stderr. Otherwise, only errors will be printed. Implies --messages.
-c, --config                     YAML configuration file with validation options. See docs/config-example.yaml for details.
-h, --threads                    The number of threads for directory validation. Set to 0 (default) for auto selection.
