So what is the suggested command line?

Or should "-a" also be included.

where filename_raw.bin contains GBytes of data. It would be good if we
in the writeup about testing includes info about how much data is needed
for different tests.

I think FredrikT started to write something about at least entropy
sources and tests.

Thanks for the help, looking forward to see you again.
