+This is a script that will export many of the variables used in this
+script. It will allow you to compile parts of the build without having
+to rebuild the entire build (e.g. recompile only the Java part).
+
+To use it, include the script into your shell, like this:
+    source env.sh
+
+Now, you can use this command to build the Java portion:
+    make -e
+
+The file will be automatically regenerated by compile.sh, so if you change
+your NDK/SDK locations or any build configurations, just re-run this
+script (sh compile.sh) and it will automatically update the file.
