+ * m_sql_log
+ *
+ * This module adds an additional target option to log{} blocks
+ * that allows logging Service's logs to SQL. To log to SQL, add
+ * the SQL service name to log:targets prefixed by sql_log:. For
+ * example:
+ *
+ * log
+ * {
+ *     targets = "services.log sql_log:mysql/main"
+ *     ...
+ * }
+ *
+ * By default this module logs to the table `logs`, and will create
+ * it if it doesn't exist. This module does not create any indexes (keys)
+ * on the table and it is recommended you add them yourself as necessary.
