+ * Revision 1.104 2007/12/18 09:08:18 hristov
+ * Splitting of the QA maker into simulation and reconstruction dependent parts (Yves)
+ *
+ * Revision 1.103 2007/11/07 11:25:06 schutz
+ * Comment out the QA checking before starting digitization
+ *
* Revision 1.102 2007/10/19 18:04:29 schutz
* The standalone QA data maker is called from AliSimulation and AliReconstruction outside the event loop; i.e. re-reading the data. The QA data making in the event loop has been commented out.
