 In order to run Quake on the simulator and/or device, you must:

+        2) Build
+	3) Install

+	5) Uninstall Quake (this step is optional)
+
+Configure the Sources
+---------------------
+
+Edit src/com/android/quake/QuakeActivity.java to configure where and how Quake will obtain its data files. The
+configuration variables are:
+
+    private final static boolean USE_INTERNAL_FLASH = true;
+    private final static boolean USE_DOWNLOADER = false;
+
+If you set them to these values, then Quake will look for its files on the internal device flash, and will not
+attempt to download the files from an external web server. (Use the ./setupdevice.sh script, described below, to
+copy the data files from the Android source tree onto the device's internal flash.)
