+
+This module adds a button on sale orders below pricelist that recalculates the
+prices of the order lines that contain a product in them.
+
+It is launched manually as a button to get the user decide if he/she wants to
+recalculate prices when pricelist is changed.
+
+Usage
+=====
+
+Inside a sale order, you can click in any moment a button called
+"(Recalculate prices)", that is next to the pricelist selection, to launch
+a recalculation of all the prices of the lines, losing previous custom prices.

+   :target: https://runbot.odoo-community.org/runbot/167/8.0
+
+Known issues / Roadmap
+======================
+
+* In a sale order with lot of lines, the recalculation may slow down, because
+  sale general data (amount untaxed, amount taxed...) are recalculated for
+  each line.
