{
if (argc < 2)
errx(1, "not enough arguments");
Mapping mapping;
if (mapping.init(argv[1]) < 0)
err(1, "loading %s", argv[1]);
const struct hash_head *heads = mapping.get<hash_head>(0, NR_HASH_HEADS);
for (unsigned head_idx = 0; head_idx < NR_HASH_HEADS; head_idx++) {

}
for (unsigned x = 0; x < chain_length; x++)
printf("%d\n", x + 1);
}
