In reference to : http://osdoc.cogsci.nl/3.1/manual/logging/
It says there : In general, you should create only one logger item, and reuse that logger at different locations in your experiment if necessary. If you create multiple loggers (rather than using a single logger multiple times), they will all write to the same log file, and the result will be a mess!
Question: Can someone explain what to do in order to 're-use a logger' ?
The tutorials just show how to 'add a logger'.
