detail about copies of cells before PBC enforced

[vasp_user]

I acknowledge that what I'm about to say is discussed in solid state text books. I also want to acknowledge that periodic boundary conditions appear in the "Pseudopotentials I" lecture from the the VASP workshop lectures which appear on the VASP website. I also did a search through the PDF version of the VASP manual.

So here is what I'm wondering: you know how in solid state physics books it imagines that you have a large number of copies of the unit cell in real space creating a macroscopic crystal... and then they explain how the k index becomes continuous etc. etc. (think big "L" in real space before the wrap around). Well where can I look up how VASP does this behind the scenes. How do the numerics go for "building the macroscopic cell" or, if it is bypassed, then where can I read about that etc.

Thanks!!!
