!****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 is depreciated in favor of H5test_kind_SIZEOF.f90 and is only
! used when the Fortran intrinsic function SIZEOF is not available. It generates
! code that does not make use of SIZEOF in H5fortran_detect.f90 which is less
! portable in comparison to using SIZEOF.
!
! The availability of SIZEOF is checked at configure time and the TRUE/FALSE
! condition is set in the configure variable "FORTRAN_HAVE_SIZEOF".
