 * The "SDK Launcher" is for Windows only.
 * This simple .exe will sit at the root of the Windows SDK
 * and currently simply executes tools\android.bat.
 * Eventually it should simply replace the batch file.
 *
 * TODO:
 * - detect that java is installed; error dialog if not, explaning where to get it.
 * - create temp dir, always copy *.jar there, exec android.jar
 * - get jars to copy from some file
 * - use a version number to copy jars only if needed (tools.revision?)
