"""diff_cluster 0.3.0: the cross-residence differential for tpc_cluster
0.3.0. Random rows, parameters and, in half the cases, a paired-SE table
(complete, or with one pair dropped, duplicated or negative); random
resolving_step inputs. Both residences run on the same inputs; 0
differences is the pass. Usage: python3 diff_cluster.py [seed] [cases]."""
