// The recommended semantics of the log levels are as follows:
//
// INFO:
// Use for state changes or other major events, or to aid debugging.
// WARNING:
// Use for undesired but relatively expected events, which may indicate a
// problem
// ERROR:
// Use for undesired and unexpected events that the program can recover from.
// All ERRORs should be actionable - it should be appropriate to file a bug
// whenever an ERROR occurs in production.
// FATAL:
// Use for undesired and unexpected events that the program cannot recover
// from.
// Annoying stuff for windows -- makes sure clients can import these functions // Annoying stuff for windows -- makes sure clients can import these functions
