TUNE b [limit] lower limit on how different a block must be to be DCT coded

TUNE d [RateScale DistortionScale] Do a DCT in the P search, not just DIFF
TUNE k [breakpt end [slope]] Squash small lum values
TUNE l Figure out Laplacian distrib and use them to dequantize and do snr calc
TUNE n Dont consider DC differenece in DCT searches
TUNE q Do MSE for distortion measure, not MAD
TUNE s [Max] | [LumMax ChromMax] Squash small differences in successive frames
TUNE u disallow skip blocks in B frames
TUNE w filename [c] Write I block distortion numbers to file [with bit-rates]
TUNE z Zaps Intra blocks in P/B frames.
[ Note k and s make -snr numbers a lie, by playing with input ]
[ Note d n and q are contradictory (can only use one) ]
