+    Add contraints in the accounting module of OpenERP to avoid bad usage by users that lead
+    to corrupted datas. This is based on our experiences and legal state of the art in other
+    software.
+    
+    Summary of constraints are:
+      
+    * Add a constraint on account move: you cannot pickup a date that is not in the fiscal year of the concerned period
+    
+    * For manual entries when multicurrency: 
+      a - Validation on the use of the 'Currency' and 'Currency Amount' fields as it is possible to enter one without the other
+      b - Validation to prevent a Credit amount with a positive 'Currency Amount', or a Debit with a negative 'Currency Amount'
+    
+    * Add a check on entries that user cannot provide a secondary currency if the same than the company one.
