   -e EXTENSION [EXTENSION ...], --extension EXTENSION [EXTENSION ...]
                         extensions of the files that we're searching (separated by spaces) for. Do not prefix them with a dot (e.g. use "py" instead of ".py"). Leave empty if you want to search for all files regardless of their extension.
