6 . Include consistency test for dtaus files. It is possible to check
7 all BLZ and KTO against some patterns. At ping.de some algorithms
8 were implemented. There's also a list of valid BLZs somewhere
10 . Add some nice GUI for control file creation
12 . Maybe add some plausibility tests for ``Ausfuehrung''
14 . Add some regression tests for automatic testing of patches
16 . In case of an error, pass the status error though the exit() routine.
18 . In case of an error, files are written half-way, ending with buggy
19 files. Maybe ftrunc() or unlink() them.
