+# This high quality math library is intended to run on either a VAX in
+# D_floating format or a machine that conforms to the IEEE standard 754
+# for double precision floating-point arithmetic.
+#
+# WARNING: On machines other than the ones mentioned above, run the original
+# Version 7 math library, if nothing better is available.
+#
+# MACHINE indicates the type of floating point hardware you are using; legal
+# values are:
+#
+# VAX          - for the VAX D_floating format, the default.
+# NATIONAL     - for those IEEE machines whose floating point implementation
+#                has similar byte ordering as the NATIONAL 32016 with 32081.
+# IEEE         - for other IEEE machines, we hope.
