This example shows 3 defect entries with 2 classifica- tion categories. You may choose classification categories and their individual entries in whichever way suits you, just use them consistently. You must not vary the number of classification categories within one input file. All events that are started must be ended. Interruptions must end before any other entry.
New phases can only start when all previous phases, defects and interruptions are ended.
Only defect entries may be nested. Display about one screenfull of options, then exit. Errors are missing or unrecognized tags, for example. Print no warnings or errors at all. Print warnings on severe errors only.
