+Description: Marking some comments as raw string literals to avoid warnings with Python 3.12.
+ In Python 3.12 when using string literals as comments, they need to by syntactically valid,
+ otherwise a SyntaxWarning instead of the previous DeprecationWarning is shown.
+ .
+ Instead of string literals for comments, actual comments (#) should be used. To keep the
+ diff in Debian small and be less invasive to upstream, raw string literals can be used as
+ a workaround as escape sequences are not parsed.
