+This option is only available on x86 systems.  This option takes the
+values x87, sse2, or auto, with auto being the default.  With the
+default value, CMUCL will check to see if the machine running CMUCL
+supports SSE2 or not.  If so, the SSE2 core file is automatically
+selected and used.  If not, the x87 core file is used.  With this
+option, the user can override the detection and select a core.  (Note
+that you cannot run the SSE2 core on a chip that doesn't not have
+SSE2.  But the x87 core can run on any machine.)
