The page hosting service like cdn and cf-pages server may need the standard exit code of the Python program to determine whether the web page is successfully built. If it is not successful, it needs to raise an exception or return a non-standard value.

Following enhancements:

• add standard exit code mappings.
• add custom exceptions.
• more environments for cdn services.
