Robust Logging Script

[David Bovill]

Anyone have any experience logging events for several days or more (an event
happens each second).... is it better to write them out as text files broken
up into a few hundred lines - or  write it to a text file using the append
syntax (not done this myself). It must be a common task that people have
done before, but as it would take a day or so to test whether I'd chosen the
most robust solution well hell thought I'd ask here :)

NB - I'll be logging geopositions and when I get the plotting code done
(thanks to all the help with the Shift Left operator guys) - i'll be able to
plot the paths on the map.
