+#### Dart CLI and Dart VM

+- The Dart CLI and Dart VM have been split into two seperate executables.
+
+  The Dart CLI tool has been split out of the VM into it's own embedder which
+  runs in AOT mode. The pure Dart VM executable is called `dartvm` and
+  has no Dart CLI functionality in it
+
+  The Dart CLI executable parses the CLI commands and invokes the rest
+  of the AOT tools in the same process, for the 'run' and 'test'
+  commands it execs a process which runs `dartvm`
+
+  `dart hello.dart` execs the `dartvm` process and runs 'hello.dart'
+
+  The Dart CLI is not generated for ia32 as we are not shipping a
+  Dart SDK for ia32 anymore (support to execute the `dartvm` for ia32
+  architecture is retained)
