Well they set the browscap setting to 'extra/browscap.ini', which isn't in my own path, so I can't modify (and update) the file.
The browscap.ini is just a normal .ini file so you can in principle use php functions to parse one yourself (php.net has some sample scripts for this).
At the moment I'm using it to detect robots in some visitor-counters, and to hide some parts of my
website hosting from them.
