+# 20140103 bernhard@intevation.de:
+#   started from 2013/getan-writeout-timesorted.py
+#   ported to python3. Removed the dependency for functions from worklog.py.
+#   the timesorted variant can be uncommented in the code for now
+# 20140109 bernhard@intevation.de:
+#   Total time output format improved.
+# 20140120 bernhard@intevation.de:
+#   added command line options, requires argparse module now (e.g. Python>=3.2)
+# 20141104 bernhard@intevation.de:
+#   migration to argparse complete, added -t option
+# TODO: 
+#  * use python v>=3.2 variants in the code where noted.
