I always planned on moving the tool into another package than com.oracle.graal.aot before integrating.  com.oracle.graal.aot suggests that it is part of Graal but it’s just an application that is using Graal.

I think we should follow what javac has:  com.sun.tools.javac

So, maybe com.oracle.tools.jaotc.
