Increasing log4j verbosity

To programmatically increase log4j verbosity, a simple code snippet does the trick:

final Logger rootLogger = Logger.getRootLogger();

        rootLogger.getLevel().toInt() + 1,

I use this to handle the -verbose command-line switch. Repeating the switch keeps increasing my program's verbosity.

Naturally there are wrinkles with a complex log4j configuration, but the idiom remains.
