Hi Alexei,
Thanks for your quick and informative reply. I will update this accordingly.
Best Regards,
Rahul

Thanks for challenging a task which may bring Harmony more interest
and customers.
BTW, I noticed that you mentioned getting feedback, testing,
publishing and implementing in your proposal. I would rather call
these items "process oriented" than "deliverable oriented". For me it
would be more interesting to hear that something works on Jikes +
Harmony, or even to know where to download a bundle capable of
launching "Hello, World". Also defining deliverables allows your
mentors to check if the project is successful.
Thanks.
