The amount of bug reports that lib would have gotten if it were 
off be default
would properly be very large.

To be frank, I would assume everybody replying to this thread, 
would have made
a better job implementing a logger than I did all that time back, 
would be able to
read the docs and insert a:

```D
void main() {
     globalLogLevel = LogLevel.off;
}
```

The docu is properly bad, but you can build hierarchies with 
MultiLogger.
