+ "Calculate a pfff-value which functions as 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.")
