-# Module 'testall'
-#
-# Python test set, should exercise:
-#	- all lexical and grammatical constructs
-#	- all opcodes from "opcode.h"
-#	- all operations on all object types
-#	- all builtin functions
-# Ideally also:
-#	- all builtin modules
-#	- all possible exception situations (Thank God we've got 'try')
-#	- all boundary cases
+# testall.py -- a regression test for the Python interpreter.
+# To run the tests, execute "import testall" in a clean interpreter.
+# It is a good idea to do this whenever you build a new interpreter.
+# Remember to add new tests when new features are added!
