+ARCHITECTURES SUPPORTED
+-----------------------
+
+Currently, x86 (i386, i486, i586, i686), x86 64-bit, PowerPC 32/64, S390, S390x
+and Sparc64 are supported. Only tested on Linux so far, but should
+theoretically work on other operating systems.

 	DEBUG_YIELD is used to add random delays in the code for testing
