Cooking my WM 6.1 ROM

[ElAguila]

It has been awhile since I cooked my custom rom. I have updated BuildOS and I remember how to buld the rom and then start the flash procedure. The one question I have is this. At the top of the BuildOS screen there is a bar with several things such as device, rev, os, ruu, and carrier. I have entered my carrier information and set the ruu to standard based on my bootloader version, the device is Apache, the os is WM6.1. The question that I have is what do I use for rev? Is this the same as the bootloader rev?
