Revision 8898

Added by Aaron Marcuse-Kubitza about 11 years ago

lib/util.sh: verbose output: use just one var ($verbosity) instead of two ($verbosity and $log_level), to track log level, for simplicity. $verbosity would now be subtracted from to alter the log level instead of $log_level being added to.
