C# Класс NVelocity.Runtime.Log.LogManager

This class is responsible for instantiating the correct LoggingSystem

The approach is :

• First try to see if the user is passing in a living object that is a LogSystem, allowing the app to give is living custom loggers.
• Next, run through the (possible) list of classes specified specified as loggers, taking the first one that appears to work. This is how we support finding either log4j or logkit, whichever is in the classpath, as both are listed as defaults.
• Finally, we turn to 'faith-based' logging, and hope that logkit is in the classpath, and try for an AvalonLogSystem as a final gasp. After that, there is nothing we can do.
