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.
