+  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.....
