[analog-help] Converting user agent strings

[David Gewirtz]

How does Analog process user agent strings? They're so inconsistent, it
doesn't seem algorithmically possible to identify browser and OS. Rather, my
guess is that it would be necessary to do some form of table lookup. But
with the new browsers out this month, do we need to update a specific table?
Does Analog get its information from a downloadable list? Is there such a
list that's updated regularly?

Thanks!
