+ * Purpose: Create two datasets (one for version 1 and one for version 2 of
+ * the layout message), which should have dimensions too large to
+ * represent in version 1 & 2 of the storage layout message.
+ * This program is used to create the test file `tlayouto.h5' which
+ * has truncated dimension information and can be used to verify that the
+ * library has fixed up the storage size correctly.
+ * To build the test file, this program MUST be compiled and linked
+ * with version hdf5-1.6.2 or _earlier_ libraries and the generated test
+ * file must be put into the 'test' directory in the 1.7+ (or 1.6+) branch
+ * of the library.
