Hi Max,

the logic for the code checkout should be something like this:

--

if cache directory exists:
  update cache directory from main repository
else:
  create cache directory by doing a clean checkout from main repository

copy cache directory into current working space
---

not a direct answer but I think it gets at your question -- does it?

cheers,
