+ * @file   bh_log.h
+ * @date   Tue Nov  8 18:19:10 2011
+ *
+ * @brief This log system supports wrapping multiple outputs into one
+ * log message.  This is useful for outputting variable-length logs
+ * without additional memory overhead (the buffer for concatenating
+ * the message), e.g. exception stack trace, which cannot be printed
+ * by a single log calling without the help of an additional buffer.
+ * Avoiding additional memory buffer is useful for resource-constraint
+ * systems.  It can minimize the impact of log system on applications
+ * and logs can be printed even when no enough memory is available.
+ * Functions with prefix "_" are private functions.  Only macros that
+ * are not start with "_" are exposed and can be used.
