+ * Created:		Dec  5, 2012
+ *			
+ *
+ * Purpose:		This machine-generated source code contains
+ *			information about the various integer and
+ *			floating point numeric formats found on this
+ *			architecture.  The parameters below should be
+ *			checked carefully and errors reported to the
+ *			HDF5 maintainer.
+ *			
+ *			Each of the numeric formats listed below are
+ *			printed from most significant bit to least
+ *			significant bit even though the actual bytes
+ *			might be stored in a different order in
+ *			memory.	 The integers above each binary byte
+ *			indicate the relative order of the bytes in
+ *			memory; little-endian machines have
+ *			decreasing numbers while big-endian machines
+ *			have increasing numbers.
+ *			
+ *			The fields of the numbers are printed as
+ *			letters with `S' for the mantissa sign bit,
+ *			`M' for the mantissa magnitude, and `E' for
+ *			the exponent.  The exponent has an associated
+ *			bias which can be subtracted to find the
+ *			true exponent.	The radix point is assumed
+ *			to be before the first `M' bit.	 Any bit
+ *			of a floating-point value not falling into one
+ *			of these categories is printed as a question
+ *			mark.  Bits of integer types are printed as
+ *			`I' for 2's complement and `U' for magnitude.
+ *			
+ *			If the most significant bit of the normalized
+ *			mantissa (always a `1' except for `0.0') is
+ *			not stored then an `implicit=yes' appears
+ *			under the field description.  In thie case,
+ *			the radix point is still assumed to be
+ *			before the first `M' but after the implicit
+ *			bit.
+ *
+ * Modifications:

+ *	DO NOT MAKE MODIFICATIONS TO THIS FILE!
