     15 
     16       It is very common to use 2 spaces wide soft-tabs, but that is not a strict
     17       requirement and you can use hard-tabs if you like that better.
     18 
     19       While this is not necessarily a concern for the correctness of your code,
     20       you should use a consistent style throughout your codebase.
