+ "pfff is a tool for calculating a compact digital fingerprint of a file
+by sampling randomly from the file instead of reading it in full.
+Consequently, the computation has a flat performance characteristic,
+correlated with data variation rather than file size. pfff can be as reliable
+as existing hashing techniques, with provably negligible risk of collisions.")
