[MEncoder-users] No such thing as Turbo for -x264encopts?

[Bill Crockett]

With -x264encopts, there is no mention of the "turbo" option for 2 pass 
encoding in the manual (man) pages under General Options.  Yet, it is 
listed in the documentation pages to use with -x264encopts showing 
examples.  Then again, the x264 command line encoder from VideoLan 
(which MEncoder uses) does not mention "turbo" in its extensive help 
listing.

Was the turbo option ever part of the -x264encopts, or is this an error 
in the documentation?
