+// The Abseil Logging library supports the following command line flags to
+// configure logging behavior at runtime:
+//
+// --stderrthreshold=<value>
+// Log messages at or above this threshold level are copied to stderr.
+//
+// --minloglevel=<value>
+// Messages logged at a lower level than this are discarded and don't actually
+// get logged anywhere.
+//
+// --log_backtrace_at=<file:linenum>
+// Emit a backtrace (stack trace) when logging at file:linenum.
+//
+// To use these commandline flags, the //absl/log:flags library must be
+// explicitly linked, and absl::ParseCommandLine() must be called before the
+// call to absl::InitializeLog().
+//
+// To configure the Log library programmatically, use the interfaces defined in
+// absl/log/globals.h.
