-                    In other words, packages are built so that they will run
-                    on the target you specify with the argument.
-                    This implies that you can build out ADT/SDK items that
-                    run on an architecture other than that of your build host.
-                    For example, you can use an x86_64-based build host to
-                    create packages that will run on an i686-based
-                    SDK Machine.
