log messages to console, depending on verbose level
|
|
|
|
Use -d to get more verbose output. The more -v you add, the
|
|
more verbose the output becomes.
|
|
|
|
Details about the running of the program go to <stderr>.
|
|
Details about scan results go to <stdout>, so that they can easily
|
|
be redirected to a file.
