Actually "debug" and "log" flags use to be confusing if the original
author didn't document the use case. Those can be either boolean
flags or integers level indicators.

For instance, in your example the "debug = 0" may have both meanings.
It's the "?" in the commentary that raises the bets towards boolean.

It's a very common practice to start with a boolean meaning and
"promote" it afterwards to a level parameter. I'm not judging that
practice here because I don't think it is a problem, it just works.
