+    'description': """
+Fields Validator
+================
+
+This module allows to set a regular expression as field validator.
+When the regular expresion is set, write and create operations on the involved
+field are blocked, if the regular expression is not satisfied.
+See demo and test data for an example with partner email.
+
+
+Configuration
+=============
+
+Open ir.model form (say res.partner) and add 'Validators' lines
+
+
+Known issues / Roadmap
+======================
+
+The module performs the check at server side. Client side check is also needed,
+to improve user experience and avoid server calls when unnecessary
