-Thanks to the work of [Tom Harrington](http://atomicbird.com/), Sparkle now supports optionally sending anonymous information about the user's system with their update. Developers can use this information to better decide what platforms and hardware to support.

 First, you've got to tell Sparkle you want this data to be sent. You can do this by adding a `SUEnableSystemProfiling` key to your app's Info.plist and setting its value to YES.
 
-Next, you've got to put something up server-side to collate and display the submitted information in a useful way. Tom Harrington has written a PHP-based backend; you can [download it here](/files/php_sparkle_stats_server.zip). Backends based on other server-side languages would be very welcome, though!
