Update xbmc library remotely

There are several solutions available for this, but all seems to call to the web interface of xbmc, you can make a script that uses curl to invoke the update library and call that with crontab/rtorrent/etc

I however settled with a simple bookmark in my browser on my workstation that leads to http://domain.something:8080/xbmcCmds/xbmcHttp?command=ExecBuiltIn&parameter=XBMC.updatelibrary(video)

You have to enable the webserver in your settings.
