SYNOPSIS
openslide-quickhash1sum [--help] [--version] slide...
DESCRIPTION
Print OpenSlide quickhash-1 checksums for one or more virtual slide
files, in a format similar to sha256sum(1).
quickhash-1 is a non-cryptographic, 256-bit hash of a subset of a
slide's data. It uniquely identifies a particular virtual slide, but
cannot be used to detect corruption or modification of the slide file.
OPTIONS

EXIT STATUS
openslide-quickhash1sum returns 0 on success, 1 if a quickhash-1 could
not be calculated, or 2 if the arguments are invalid.
BUGS
quickhash-1 is not defined for all slide files supported by OpenSlide.
If a slide does not have a quickhash-1, "No quickhash-1 available" will
be printed.
