Any documentation that exists is likely horribly out of date
considering how much the ratecontrol has changed over the years.

If you don't count things like macroblock-tree and adaptive
quantization, 1/2-pass mode are not very different from libavcodec's
ratecontrol, albeit VBV is completely different, as is CRF.

If you have specific questions, you can ask in #x264dev on Freenode.
