Thanks for the response.
- I will need to probably read up on egg files and packaging.. I am
not too familiar in that area.
- Will also look up tools suggested by you.
-- Version set sound like the right way to do things. I am assuming

versions as a single unit. Is this something you can share ? Also is
Easterbunny something you wrote ? Could not spot it in my search.
