 * be false for "make check" to succeed, but may be set to true at other
 * times for debugging purposes.
 *
 * Hence the following, somewhat odd set of #defines.
 *
 * NOTE: test/cache plays games with the f->shared->cache, and thus
 *       setting H5AC_DUMP_STATS_ON_CLOSE will generate constant,
 *       irrelevant data when run with that test program.  See
 *       comments on setup_cache() / takedown_cache() in test/cache_common.c.
 *       for details.
 *
 *     If you need to dump stats at file close in test/cache.c,
 *     use the dump_stats parameter to takedown_cache(), or call
 *     H5C_stats() directly.
 *                    JRM -- 4/12/15
 *
 * Added the H5AC_DUMP_IMAGE_STATS_ON_CLOSE #define, which works much
 * the same way as H5AC_DUMP_STATS_ON_CLOSE.  However, the set of stats
 * displayed is much smaller, and directed purely at the cache image feature.
