+/**
+ * A virtual machine compiler-runtime interface (CRI).
+ * <p>
+ * Specifically, this package defines an interface between the compiler and the runtime system of a virtual machine for
+ * the instruction set defined in {@link com.sun.cri.bytecode.Bytecodes}. The interface has three components:
+ * <ol>
+ * <li>the {@link com.sun.cri.ci compiler-provided interface} that must be used by the runtime.
+ * <li>the {@link com.sun.cri.ri runtime-provided interface} that must be used by the compiler.
+ * <li>the {@link com.sun.cri.xir XIR interface} for translating object operations.
+ * </ol>
+ *
+ * The interface is independent of any particular compiler or runtime implementation.
+ * <p>
+ * For more details see <a href="http://wikis.sun.com/download/attachments/173802383/vee2010.pdf">Improving Compiler-Runtime Separation with XIR</a>.
