It's documented on that page.
It says """The action names can be abbreviated as desired and the
interpreter will resolve them to the appropriate action name. For
example, -Wi is the same as -Wignore."", so "python -Wa" is the same as
"python -Walways".
It also says """-Werror # Convert to exceptions""", so "python
-Werror" (or "python -We") will convert all warnings to exceptions.
