This article is a comparison of seven CPAN modules for extracting information out of the User-Agent string passed to web sites by browsers, spiders, and other software agents. These are useful when processing log files, to produce analytics, and other purposes. You may even use it to change your application's behaviour, but that sort of thing is frowned upon.
