-Run Regression Test Suite

 This module calls down into individual test cases via subprocess. It will
-forward all unrecognized arguments onto the individual test scripts, other
-than:
+forward all unrecognized arguments onto the individual test scripts.
 
-    - `-extended`: run the "extended" test suite in addition to the basic one.
-    - `-win`: signal that this is running in a Windows environment, and we
-      should run the tests.
-    - `--coverage`: this generates a basic coverage report for the RPC
-      interface.
+RPC tests are disabled on Windows by default. Use --force to run them anyway.
 
 For a description of arguments recognized by test scripts, see
