+ALTERNATE PYTHON IMPLEMENTATIONS
+--------------------------------
+The test suite restricts itself to largely Python 2.3-level constructs and
+standard library features, with the notable exception of decorators, which are
+used extensively throughout the suite.
+
+A source transformation tool is included that allows testing on Python 2.3 or
+any other Python implementation that lacks @decorator support.
+
+To use it:
+
+  $ python test/clone.py -c --filter=py23 test23
+
+This will copy the test/ directory structure into test23/, with @decorators in
+the source code transformed into 2.3-friendly syntax.
