Thanks!

I see there is the `ln` alias. So I tried to replace the following line
    file link   ${worksrcpath}/TestBitVector/BitVector.py ../BitVector.py 

 with
    ln ../BitVector.py  ${worksrcpath}/TestBitVector/BitVector.py 

The first works the second fails, so what is I understood wrong?

I did, but the result is exactly the same. I actually, had it like this before but added the mkdir as an experiment.

Here, it seems to be slightly different. I experimented with and without trailing `/` but nothing changes. For Unix `cp -R` this matter!
