"""write a daily report accessing a database from http://hg.intevation.de/getan 1.1dev3."""
# hastily done, written to learn the getan database format and its manipulation
# Free Software under GNU GPL v>=3
# 20130109 bernhard@intevation.de
# 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.
