49 -d PATH, --dataset PATH
50 specify the dataset to add files to. If no dataset is given, an
51 attempt is made to identify the dataset based on the current

53 dataset. Constraints: Value must be a Dataset or a valid identi‐
54 fier of a Dataset (e.g. a path) or value must be NONE

56 -O PATH, --path PATH
57 target for download. If the path has a trailing separator, it is
58 treated as a directory, and each specified URL is downloaded un‐

60 trailing separator, the value specifies the name of the down‐
61 loaded file (file name extensions inferred from the URL may be
62 added to it, if they are not yet present) and only a single URL
63 should be given. In both cases, leading directories will be cre‐
64 ated if needed. This argument defaults to the current directory.
65 Constraints: value must be a string or value must be NONE
