	Because the maximum length of the argument is 255 bytes, if you have a longer stream to decode, you can do it in pieces, where any piece is a multiple of 4 bytes long (3 bytes are evenly packed into 4 bytes of a base 64 encoding). For example, if you have a valid base 64 string which is the concatenation of items in a Sirius $list and you wish to print that string, possibly producing multiple lines of length 60, you can use the following approach:		Because the maximum length of the argument is 255 bytes, if you have a longer stream to decode, you can do it in pieces, where any piece is a multiple of 4 bytes long (3 bytes are evenly packed into 4 bytes of a base 64 encoding).
