+// C/C++ logging functions. See the logging documentation for API details.
+//
+// We'd like these to be available from C code (in case we import some from
+// somewhere), so this has a C interface.
+//
+// The output will be correct when the log file is shared between multiple
+// threads and/or multiple processes so long as the operating system
+// supports O_APPEND. These calls have mutex-protected data structures
+// and so are NOT reentrant. Do not use LOG in a signal handler.
