+/**
+ * A DataMapper client class that can load a cached SqlMapper. Give the configuration
+ * file, it looks for a .cache file containing serialized TSqlMapClient instance to
+ * load. Usage:
+ *
+ * <code>
+ * $client = new TSqlMapClient;
+ * $sqlmap = $client->configure($configFile, true); //load from cache.
+ * $products = $sqlMap->queryForList('statementName');
+ * </code>
+ *
+ * To save the TSqlMapper instance to cache for later usage, call
+ * cacheConfiguration().
