"""Modifies the Android SDK to build Android Scripting Environment.

This script compiles android.os.Exec from the Android source and adds the
class to the Android SDK android.jar. In addition, it copies the source files
into the SDK so that they can be browsed from Eclipse.

In order to use this script, you must have download the Android source and
installed the Android SDK.
