-        `data_dict` is a dict containing field names as
-        keys. `context` is an object or string.
-
-        `data_dict` gives the values to set on an object where the
-        dict contains the attribute names as keys and values to set as
-        values. Values and keys have to be strings.
-
-        If `context` is a string, this is understood as a factory name
-        and we will try to create a proper object calling
-        ``createObject()``. If it is an object then we will update
-        this object.
-
-        `form_fields` are by default (``None``) buildt from the given
-        `iface` but can also be passed in to override the
-        default. This might be handy if you want to omit or select
-        certains fields from the interface.

-        happened), ``INV_ERR_LIST`` is a list of invariant errors
-        happened (errors that apply to several fields), and ``OBJ`` is
-        the created/updated object.

+
+        `data_dict` is a mapping (dict) from field names to values
+        represented as strings.

+        The fields (keys) to convert can be given in optional

+        example created by :class:`grok.AutoFields`.
+
+        If no `form_fields` are given, a default is computed from the
