Regarding output of pull_library.sh

[Anil-rayala]

Hi,
Can you please help clarify the below query.
After executing pull_library.sh , a directory named "vendor" is created.
Where should we copy this folder to, in our already synced android source code tree?
It is written in READ.md that we should copy this to root of the tree but I see there is already a vendor folder existing when code is synced from repo.
