+			   Extended ODBC class for Sybase SQLAnywhere.
+   1) Added support to retrieve the last row insert ID on tables with
+	  primary key column using autoincrement function.
+
+   2) Added blob support.  Usage:
+		 a) create blob variable on db server:
+
+		$dbconn->create_blobvar($blobVarName);
+
+	  b) load blob var from file.  $filename must be complete path
+
+	  $dbcon->load_blobvar_from_file($blobVarName, $filename);
+
+	  c) Use the $blobVarName in SQL insert or update statement in the values
+	  clause:
+
+		$recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
+		.
+	   'VALUES (\'test\', ' . $blobVarName . ')');
+
+	 instead of loading blob from a file, you can also load from
+	  an unformatted (raw) blob variable:
+	  $dbcon->load_blobvar_from_var($blobVarName, $varName);
+
+	  d) drop blob variable on db server to free up resources:
+	  $dbconn->drop_blobvar($blobVarName);
+
+  Sybase_SQLAnywhere data driver. Requires ODBC.
