1 The log module provides a simple interface for application logging. The 2 [[logger]] interface provides an abstraction that users may implement for custom 3 logging logic. We provide a simple logger implementation that prefixes each line 4 with the current timestamp; to initialize such a logger see [[new]]. 5 6 A global logger is also provided for simple applications to use, [[global]], 7 which is an instance of the standard logger that writes to [[os::stderr]] by 8 default. The user may configure a new global logger via [[setlogger]].
