5  * tdb2 - [[WORK IN PROGRESS!]] The trivial (64bit transactional) database
6  *
7  * The tdb2 module provides an efficient keyword data mapping (usually
8  * within a file).  It supports transactions, so the contents of the
9  * database is reliable even across crashes.

12  *      #include <ccan/tdb2/tdb2.h>
13  *      #include <ccan/str/str.h>
14  *      #include <err.h>
15  *      #include <stdio.h>

20  *                   "OR %s store <dbfile> <key> <data>", argv0, argv0);
21  *      }
