gopkg.in/go-dedup/simhash.v2 (go): simhash package implements Charikar's simhash algorithm to generate a 64-bit fingerprint of a given document.  simhash fingerprints have the property that similar documents will have a similar fingerprint. Therefore, the hamming distance between two fingerprints will be small if the documents are similar  for standalone test, change package to `main` and the next func def to, func main() {
