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.
