=======================
What is

X:\>bogoutil.exe -v
bogoutil: Exactly one of the -C, -d, -f, -F, -P, -l, -R or -w flags must 
be present.
But from Usage string it follows that  we can use "bogoutil.exe -v"

X:\>bogoutil.exe -m
X:\bogoutil.exe: option requires an argument -- m
Option -m requires an argument.

There is no "m" in usage string and there is no argument to "m" in 
online help

May be there are also some other  inaccuracies in BogoUtil -h
