Overview

The dumper is a specific Logger::Backend.

It react to method calls by writting in the output. The output must be acceded like that:

* Using the print method
* Using the puts method
* Using the << method

If you really need to access to the real outputs use each_output.

You can safely call flush in your methods because this method take care of closed and unflushable outputs.
