+Summary: Standard screen saver collection shipped on most Linux and Unix systems
+Description: |
+    XScreenSaver has about 150 different live wallpapers (and now daydreams as well) to use on your screen - with more coming in future editions!  This is one of the best and most robust live wallpaper apps out there.
+
+    The Android port is fairly recent, some of the demos don't work yet.
+
+    If you are an Android developer and you'd like to help us finish it, source code is available at [https://www.jwz.org/xscreensaver/].

+
+MaintainerNotes: |
+    `make all` already does the gradle build. Running gradle standalone doesn't work as is afterwards beause of undefined env variables.
+    Disabling the preBuild tasks in the gradle file works around this issue.
