Doc written in timeout. Everything else in this file was done while
the timer was running.
I promised "Mark Kopecki" that writing the bin-to-intel-hex
converter would cost less than 15 minutes, and that it would be more
trouble to find a converter on the net than to write the converter
myself. I ended up spending over half an hour searching for
spec/converter/docs because of unreachable hosts on the internet. I
got a file with docs, after that it was 8 minutes.....
