+# Because of Sparkle.framework weirdness, "XScreenSaverUpdater.app" is
+# in the DMG as a compressed tar file instead of an app, and we unpack
+# it when installing. Without this, auto-updates won't work: If there's
+# an .app there, Sparkle thinks that "XScreenSaverUpdater.app" is the
+# thing it should be updating instead of "Install Everything.pkg".
