%global _description %{expand:
TLSH is a fuzzy matching library. Given a byte stream with a minimum length of
256 bytes (and a minimum amount of randomness), TLSH generates a hash value
which can be used for similarity comparisons.  Similar objects will have similar
hash values which allows for the detection of similar objects by comparing their
hash values.}
