+Web Option Auto Color
+=====================
+
+This module was written to offer a new autocolor attribute which can be used on
+field in trees view. Using this attribute causes an identical coloration for
+cells of the same value in a list view.
+
+Installation
+============
+
+To install this module, you need to:
+
+ * Click on install button
+ 
+ Usage
+ =====
+ 
+ In the view declaration, put autocolor="1" attribute in the field tag::
+
+    ...
+    <field name="arch" type="xml">
+        <tree string="View name">
+            ...
+            <field name="name"/>
+            <field name="name2" autocolor="1"/>
+            ...
+        </tree>
+    </field>
