* Purpose: This program is run to generate an HDF5 data file with both
* empty and compact groups.
*
* To test compatibility between v1.6 and v1.7, compile and run
* this program, it will generate a file called "group_new.h5".
* You need to move it to the test directory in the HDF5 v1.6
* source tree. The test/stab.c program will read it.
