A glance at the source code (utilities/logger.py) indicates to me that yt is using the Python logging package for output information, and that depending on the choice of the option stdoutStreamLogging, this can be directed to either stdout or stderr. Since there's a lot of information piped to stdout whenever a dataset is opened, and this can tend to overwhelm any other information that is being displayed to screen it would be nice if the logging output could be redirected to a file. This can be done when setting the basicConfig for the logger when setting it up, but that page indicates that this configuration cannot be overridden after it has initially been set. Is there a way to include an option in yt for the user to direct the logging output to a file of their choice?
