Package-specific debug options

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I needed a version of CUPS with more debugging enabled.
Is there a standard policy on how to call such debug options?
I did the following:

First question: should the first option be called "debug" or "cups-debug".
The second option is probably CUPS-specific enough to be called 
"cups-debug-printf"

Second question: Is that trivial patch of mine useful enough for other people 
so that someone could commit it?
