+JIT-specific configuration
+--------------------------
+
+A Just-In-Time (JIT) translation engine is available for x86. This is
+aimed at translating 68040 instructions to native equivalent code
+sequences, thus providing faster emulation speeds.
+
+  jit <"true" or "false">
+
+    Set this to "true" to enable the JIT compiler. Default value is
+    "true" if the JIT compiler was compiled in. Besides, this is
+    effective only if Basilisk II is configured to emulate a 68040.
+
+  jitfpu <"true" or "false">
+
+    Set this to "true" to enable translation of floating-point (FPU)
+    instructions. Default is "true".
+
+  jitcachesize <size>
+
+    Allocate "size" kilobytes of RAM for the translation cache. The
+    value given will be rounded down to the nearest multiple of a page
+    size. Minimal value is "2048" (2MB). Default value is "8192" (8MB).
+
+  jitlazyflush <"true" or "false">
+
+    Set this to "true" to enable lazy invalidation of the translation
+    cache. This is always recommended as it usually makes the system
+    more responsive and faster, especially while running MacOS
+    8.X. Default value is "true".
+
+  jitdebug <"true" or "false">
+
+    Set this to "true" to enable the JIT debugger. This requires a
+    build of Basilisk II with the cxmon debugger. Default is "false".
