-// The test uses an array to compare against values written to the database.
-// Keys written to the array are in 1:1 correspondence to the actual values in
-// the database according to the formula in the function GenerateValue.
-
-// Space is reserved in the array from 0 to FLAGS_max_key and values are
-// randomly written/deleted/read from those positions. During verification we
-// compare all the positions in the array. To shorten/elongate the running
-// time, you could change the settings: FLAGS_max_key, FLAGS_ops_per_thread,
-// (sometimes also FLAGS_threads).
-//
-// NOTE that if FLAGS_test_batches_snapshots is set, the test will have
-// different behavior. See comment of the flag for details.
