With no FILE, or when FILE is -, read standard input.
The data are encoded as described for the base64 alphabet in RFC 3548.
When decoding, the input may contain newlines in addition to the bytes of
the formal base64 alphabet. Use --ignore-garbage to attempt to recover
from any other non-alphabet bytes in the encoded stream.
