// The LogDiagnosticCommand represents the 'VM.log' DCMD
// that allows configuration of the logging at runtime.
// It can be used to view or modify the current log configuration.
// VM.log without additional arguments prints the usage description.
// The 'list' argument will list all available log tags,
// levels, decorators and currently configured log outputs.
// Specifying 'disable' will disable logging completely.
// The remaining arguments are used to set a log output to log everything
// with the specified tags and levels using the given decorators.
