+Stock Reserve
+=============
+
+Allows to create stock reservations on products.
+
+Each reservation can have a validity date, once passed, the reservation
+is automatically lifted.
+
+The reserved products are substracted from the virtual stock. It means
+that if you reserved a quantity of products which bring the virtual
+stock below the minimum, the orderpoint will be triggered and new
+purchase orders will be generated. It also implies that the max may be
+exceeded if the reservations are canceled.

+Stock Reserve Sales
+===================
+
+Allows to create stock reservations for quotation lines before the
+confirmation of the quotation.  The reservations might have a validity
+date and in any case they are lifted when the quotation is canceled or
+confirmed.
+
+Reservations can be done only on "make to stock" and stockable products.
+
+The reserved products are substracted from the virtual stock. It means
+that if you reserved a quantity of products which bring the virtual
+stock below the minimum, the orderpoint will be triggered and new
+purchase orders will be generated. It also implies that the max may be
+exceeded if the reservations are canceled.
+
+If you want to prevent sales orders to be confirmed when the stock is
+insufficient at the order date, you may want to install the
+`sale_exception_nostock` module.
