Re: My first nimble package

[Stefan_Salewski]

Well, this is the cleaned up version. We do check for dev packages on ubuntu, 
check if tmp dir already exists and delete tmp dir when done. Problem with mode 
= Whatif was that Whatif is a pure enum, issue is posted. The modules still 
import each other directly, without the gintro prefix. Seems to work fine, I 
hope that is indeed intended and desired.

I can install my local package fine with "nimble prepare", "nimble install".

I think I can not avoid that nimble prepare. But I am still not sure if "nimble 
prepare" will work for remote packages at all!
