DESCRIPTION

18       Print  OpenSlide  quickhash-1  checksums  for one or more virtual slide
19       files, in a format similar to sha256sum(1).
20
21       quickhash-1 is a non-cryptographic, 256-bit  hash  of  a  subset  of  a
22       slide's  data.   It uniquely identifies a particular virtual slide, but
23       cannot be used to detect corruption or modification of the slide file.

42       be printed.
