+
+	# search for a certain note

+        $db->use_crypt("passphrase", "CryptMethod");

+
+
+=head1 DESCRIPTION
+
+You can use this module for accessing a note database. This backend uses
+a text file for storage and Storable for accessing the file.
+
+Currently, NOTEDB module is only used by note itself. But feel free to use it
+within your own project! Perhaps someone want to implement a webinterface to
+note...
+
+=head1 USAGE
+
+please see the section SYNOPSIS, it says it all.
