+ * res_config_mysql.c <mysql plugin for RealTime configuration engine>
+ *
+ * v2.0   - (10-07-05) - mutex_lock fixes (bug #4973, comment #0034602)
+ *
+ * v1.9   - (08-19-05) - Added support to correctly honor the family database specified
+ *                       in extconfig.conf (bug #4973)
+ *
+ * v1.8   - (04-21-05) - Modified return values of update_mysql to better indicate
+ *                       what really happened.
+ *
+ * v1.7   - (01-28-05) - Fixed non-initialization of ast_category struct
+ *                       in realtime_multi_mysql function which caused segfault. 
+ *
+ * v1.6   - (00-00-00) - Skipped to bring comments into sync with version number in CVS.
+ *
+ * v1.5.1 - (01-26-05) - Added better(?) locking stuff
+ *
+ * v1.5   - (01-26-05) - Brought up to date with new config.h changes (bug #3406)
+ *                     - Added in extra locking provided by georg (bug #3248)
+ *
+ * v1.4   - (12-02-04) - Added realtime_multi_mysql function
+ *                        This function will return an ast_config with categories,
+ *                        unlike standard realtime_mysql which only returns
+ *                        a linked list of ast_variables
+ *
+ * v1.3   - (12-01-04) - Added support other operators
+ *                       Ex: =, !=, LIKE, NOT LIKE, RLIKE, etc...
+ *
+ * v1.2   - (11-DD-04) - Added reload. Updated load and unload.
+ *                       Code beautification (doc/CODING-GUIDELINES)
