+The "generic_mips" product defines a MIPS based non-hardware-specific
+target without a kernel or bootloader.
+
+It can be used to build the entire user-level system, and
+will work with the emulator, though sound will not work
+(see the "emulator" product for that).
+
+It is not a product "base class"; no other products inherit
+from it or use it in any way.
