+Web widget radio tree
+=====================
+
+This module allows to use input radio in a tree view inside a form, in order to ensure the user marks only one record.
+
+Example: You have a partner company from with many contacts. The contacts are shown in a tree and you want to specify only one as preferred.
+
+Usage
+=====
+
+In the view declaration, put widget='radio_tree' attribute in the field tag::
+
+    ...
+    <field name="arch" type="xml">
+        <form>
+            ...
+            <field name="name" />
+            <field name="contact_ids">
+                <tree string="View name">
+                    ...
+                    <field name="name"/>
+                    <field name="preferred" widget="radio_tree"/>
+                    ...
+                </tree>
+            </field>
+        </form>
+    </field>
+    ...
