data LoggerDetails

A way to set more fined-grained configuration for specific log messages.

Name, package, and module are "selectors" that identify which messages should be configured. Any absent "selectors" match everything. Name and package have to match exactly. Module can either match exactly, or -- if the config specifies a module ending in an asterisk -- match a prefix.

loggerLevel is a "minimum priority". Messages that aren't at least as severe as this will not be logged.
