   FILE
   testhdf5.c - HDF5 testing framework main file.

   REMARKS
   General test wrapper for HDF5 base library test programs

   DESIGN
   Each test function should be implemented as function having no
   parameters and returning void (i.e. no return value).  They should be put
   into the list of InitTest() calls in main() below.  Functions which depend
   on other functionality should be placed below the InitTest() call for the
   base functionality testing.
   Each test module should include testhdf5.h and define a unique set of
   names for test files they create.

   BUGS/LIMITATIONS

   EXPORTED ROUTINES/VARIABLES:
   Two variables are exported: num_errs, and Verbosity.
