!****p* Program/H5test_kind
!
! NAME
!  Executable: H5test_kind
!
! FILE
!  fortran/src/H5test_kind.f90
!
! PURPOSE
!  This stand alone program is used at build time to generate the program
!  H5fortran_detect.f90. It cycles through all the available KIND parameters for
!  integers and reals. The appropriate program and subroutines are then generated
!  depending on which of the KIND values are found.
!
! NOTES
!  This program uses the Fortran 2008 intrinsic function STORAGE_SIZE or SIZEOF 
!  depending on availablity.It generates code that makes use of 
!  STORAGE_SIZE/SIZEOF in H5fortran_detect.f90. STORAGE_SIZE is standard
!  compliant and should always be chosen over SIZEOF.
!
!  The availability of STORAGE_SIZE/SIZEOF is checked at configure time and the TRUE/FALSE
!  condition is set in the configure variable "FORTRAN_HAVE_STORAGE_SIZE" or
!  "FORTRAN_HAVE_SIZEOF".
!
!  The use of C_SIZOF(X) is not used since the argument X must be an interoperable
!  data entity.
