[Bioperl-l] How to get rid of warnings

Well, the rule would be:

	1) if a local (instance) verbosity has been set, use it
	2) otherwise, if a global (class, static) verbosity has been set,  
use it
	3) otherwise, use a default value.

This would mean indeed that if you changed verbosity for a specific  
instance it will be unaffected by global changes of the verbosity level.

If that doesn't sound good, you would reverse rules 1) and 2).

Or am I missing something?
