+      XWinWrap is a small utility written a loooong time ago that allowed you to
+      stick most of the apps to your desktop background. What this meant was you
+      could use an animated screensaver (like glmatrix, electric sheep, etc) or
+      even a movie, and use it as your wallpaper. But only one version of this
+      app was ever released, and it had a few problems, like:
+
+      - Well, sticking didn’t work. So if you did a “minimize all” or “go to
+      desktop” kind of thing, your “wallpaper” got minimized as well.
+
+      - The geometry option didn’t work, so you could not create, e.g., a small
+      matrix window surrounded by your original wallpaper.
+
+      Seeing no-one picking it up, I decided to give it a bit of polish last
+      weekend by fixing the above problems and also add a few features. And here
+      it is, in its new avatar “Shantz XWinWrap”.
