+setup steps:
+
+* Run `ubuntu-setup.sh` to install required packages and setup the `/data/` folder (see below).
+
+* Install the Android SDK at `$HOME/lib/android-sdk`. Override this by setting the environment
+variable `$ANDROID_HOME` to point at another location.
+
+* Install the Android NDK, version r10e, at `$HOME/lib/android-ndk`. Override this by setting
+the environment variable `$NDK` to point at another location.
