+# SYNOPSIS
+#
+#   AX_LIB_HDF5([serial/parallel])
+#
+# DESCRIPTION
+#
+#   This macro provides tests of the availability of HDF5 library.
+#
+#   The optional macro argument should be either 'serial' or 'parallel'. The
+#   former only looks for serial HDF5 installations via h5cc. The latter
+#   only looks for parallel HDF5 installations via h5pcc. If the optional
+#   argument is omitted, serial installations will be preferred over
+#   parallel ones.
+#
+#   The macro adds a --with-hdf5 option accepting one of three values:
+#
+#     no   - do not check for the HDF5 library.
+#     yes  - do check for HDF5 library in standard locations.
+#     path - complete path to the HDF5 helper script h5cc or h5pcc.
+#
+#   If HDF5 is successfully found, this macro calls
+#
+#     AC_SUBST(HDF5_VERSION)
+#     AC_SUBST(HDF5_CC)
+#     AC_SUBST(HDF5_CFLAGS)
+#     AC_SUBST(HDF5_CPPFLAGS)
+#     AC_SUBST(HDF5_LDFLAGS)
+#     AC_SUBST(HDF5_LIBS)
+#     AC_SUBST(HDF5_FC)
+#     AC_SUBST(HDF5_FFLAGS)
+#     AC_SUBST(HDF5_FLIBS)
+#     AC_DEFINE(HAVE_HDF5)
+#
+#   and sets with_hdf5="yes".  Additionally, the macro sets
+#   with_hdf5_fortran="yes" if a matching Fortran wrapper script is found.
+#   Note that Autconf's Fortran support is not used to perform this check.
+#   H5CC and H5FC will contain the appropriate serial or parallel HDF5
+#   wrapper script locations.
+#
+#   If HDF5 is disabled or not found, this macros sets with_hdf5="no" and
+#   with_hdf5_fortran="no".
+#
+#   Your configuration script can test $with_hdf to take any further
+#   actions. HDF5_{C,CPP,LD}FLAGS may be used when building with C or C++.
+#   HDF5_F{FLAGS,LIBS} should be used when building Fortran applications.
+#
+#   To use the macro, one would code one of the following in "configure.ac"
+#   before AC_OUTPUT:
+#
+#     1) dnl Check for HDF5 support
+#        AX_LIB_HDF5()
+#
+#     2) dnl Check for serial HDF5 support
+#        AX_LIB_HDF5([serial])
+#
+#     3) dnl Check for parallel HDF5 support
+#        AX_LIB_HDF5([parallel])
+#
+#   One could test $with_hdf5 for the outcome or display it as follows
+#
+#     echo "HDF5 support:  $with_hdf5"
+#
+#   You could also for example, override the default CC in "configure.ac" to
+#   enforce compilation with the compiler that HDF5 uses:
+#
+#     AX_LIB_HDF5([parallel])
+#     if test "$with_hdf5" = "yes"; then
+#             CC="$HDF5_CC"
+#     else
+#             AC_MSG_ERROR([Unable to find HDF5, we need parallel HDF5.])
