dnl The following variables are used to distinguish between building a

dnl
dnl    HAVE_PARALLEL	-- defined in H5config.h if we are building
dnl			   a parallel library even if configure wasn't
dnl			   able to find some header file or library that
dnl			   might be required. This is defined if the
dnl			   compiler looks like a parallel compiler (e.g.,
dnl			   mpicc or mpcc) or if the user explicitly states
dnl			   that a parallel library is being built by supplying
dnl			   the `--enable-parallel' configure switch.
dnl
dnl    PARALLEL		-- This variable is set to a non-null value if
dnl			   configure thinks we're compiling a parallel
dnl			   version of the library.
dnl
dnl    RUNSERIAL	-- This is a command which will be prepended to
dnl			   the executable name to run the executable using
dnl			   a single process. For serial versions of the
dnl			   library this will normally be empty. For parallel
dnl			   versions it might be something like `mpirun -np 1'.
dnl			   The value of this variable is substituted in *.in
dnl			   files.
dnl
dnl    RUNPARALLEL	-- This is a command which will be prepended to
dnl			   the executable name to run the executable on
dnl			   multiple processors. For the serial library the
dnl			   value will normally be the empty string. For
dnl			   parallel library it should be something like
dnl			   `mpi -np $$NPROCS' where NPROCS will eventually
dnl			   contain the number of processors on which to run
dnl			   the executable (the double dollarsigns are to
dnl			   protect the expansion until make executes the
dnl			   command).  The value of this variable is
dnl			   substituted in *.in files.
