  === Alerting from TL Loading
  
  DSS allows running of custom alerts in some situations (eg : invalid TL signature, LOTL location change,...). Alert works with two concepts : detection and alert handler. After the download/parsing/validation and before the synchronization, the results are tested to detect events and launch alert(s).
