The app is basically just a wrapper for a simple shell script. To use it, just double-click the application icon and it should clear all growl notifications and close. There is no interface, so it will appear that it's not doing anything at all unless you have some growl messages displayed.
To install it, simply clone it into your applications folder (or wherever you want, really) :
> cd /Applications > git clone git://github.com/recurser/ClearGrowl.app.git
If you come across any problems, please create a ticket and we'll try to get it fixed as soon as possible.
