+===================
+Permanent Lock Move
+===================
+
+This module extends the functionality of the basic "lock date"
+functionality in invoicing, in order to add a more definitive
+lock date (which does not allow to be set at a previous date,
+or emptied, and only accepts unposted moves)
+
+Configuration
+=============
+
+To configure this module, you need to:
+
+* Go to Invoicing -> Settings, and set the Permanent Lock Date.
