+ Mono has now gone through three different JIT engines, these
+ are:
+
+ * Original JIT engine: 2002, hard to port, hard to
+ implement optimizations.
+
+ * Second JIT engine, used up until Mono 2.0, very
+ portable, many new optimizations.
+
+ * Third JIT engine, replaced the code generation layer from
+ being based on a tree representation to be based on a linear
+ representation.
+
+ For more information on the code generation changes, see our
+ web site for the details on the Linear IL:
