/**
 * tdb - The trivial (transactional) database
 *
 * The tdb module provides an efficient keyword data mapping (usually
 * within a file).  It supports transactions, so the contents of the
 * database is reliable even across crashes.
 *
 * Example:
 *	#include <ccan/tdb/tdb.h>
 *	#include <ccan/str/str.h>
 *	#include <err.h>
 *	#include <stdio.h>
 *	
 *	static void usage(void)
 *	{
 *		errx(1, "Usage: %s fetch <dbfile> <key>\n"
 *		     "OR %s store <dbfile> <key> <data>");
 *	}
 *	
 *	int main(int argc, char *argv[])
 *	{
 *		struct tdb_context *tdb;
 *		TDB_DATA key, value;
 *	
 *		if (argc < 4)
 *			usage();
 *	
 *		tdb = tdb_open(argv[2], 1024, TDB_DEFAULT, O_CREAT|O_RDWR,
 *				0600);
 *		if (!tdb)
 *			err(1, "Opening %s", argv[2]);
 *	
 *		key.dptr = (void *)argv[3];
 *		key.dsize = strlen(argv[3]);
 *	
 *		if (streq(argv[1], "fetch")) {
 *			if (argc != 4)
 *				usage();
 *			value = tdb_fetch(tdb, key);
 *			if (!value.dptr)
 *				errx(1, "fetch %s: %s",
 *				     argv[3], tdb_errorstr(tdb));
 *			printf("%.*s\n", value.dsize, (char *)value.dptr);
 *			free(value.dptr);
 *		} else if (streq(argv[1], "store")) {
 *			if (argc != 5)
 *				usage();
 *			value.dptr = (void *)argv[4];
 *			value.dsize = strlen(argv[4]);
 *			if (tdb_store(tdb, key, value, 0) != 0)
 *				errx(1, "store %s: %s",
 *				     argv[3], tdb_errorstr(tdb));
 *		} else
 *			usage();
 *	
 *		return 0;
