VOV: How do I increase tool verbosity?

Many commands offer the option -v to increase the verbosity. Some message require a higher verbosity level to be printed. The higher level can be invoked by specifying '-v' multiple times. For example:

nc run -v -v -v <command>

Another way to change the overall verbosity of a tool is to add the corresponding 'config.tcl' file:

set vovutils(verbose) 2
