+This module complements the mrp_multi_level module by allowing to set a
+date on the mrp.area records until which no attempt to rebuild safety
+stock will be attempted: the safety stock will be used, if the running
+stock get below zero, then a resupply will be created to bring back the
+stock to zero.
+
+The idea is that your area may be under tension at a given moment (maybe
+some workers are off, maybe there is high demand from customers) and you
+can barely keep up with the demand. In this case, you can set Safety
+stock rebuild lead date to a date in the future at which you anticipate
+that the situation will have been fixed.

+
+Usage
+=====
+
+When this module is installed, you get an additional parameter on the
+mrp.area records:
+
+- Safety stock lead date
+
+Until that date, the MRP Multi Level planner will consume the safety
+stock without attempting to rebuild it, and only resupply if the
+forecasted stock goes below zero.
+
+If the date is in the paste, nothing special happens.
