concept2 utility batch mode

[coastline]

I would like to run the concept2 utility from a batch file, typically to upload the days
training data to the online logbook.

I can do it by automating the interaction by scripting, but it is a bit complicated due to
the announcements of available updates appearing at random times.

So, what I ask for is a way to start the utility program in a non-interactive mode, with
the actions given by supplied parameters or an input file. Error messages should be dumped to file.
