A really simple Jenkins build notification app for Windows. Keep an eye on your builds from the system tray!
Either Download and run the latest exe or open butler.sln in Visual Studio 2015 and press F5.
The settings screen will then ask for the HTTP path to your Jenkin's cc.xml e.g. http://jenkins/cc.xml. Settings are stored in a settings.ini alongside the exe.
The focus for this app is on minimal use of resources - the exe is 1.1MB and eats a whole 1.7MB of memory when running!
