i have further questions regarding pvanal.

running pvanal without arguments i see this:

Options:
    -c 
    -b 
    -d 
    -n 
    -w  | -h 
    -g | -G 
    -v | -V 
    -H: use Hamming window instead of the default (Hanning)
    -K: use Kaiser window

1) i haven't found documentation explaining the -g/G and -v/V flags. what do
they mean?

2) is the kaiser window really implemented? what's the value of alpha? or is
it configurable, and how? 

is the kaiser window also implemented in the pvsanal opcode? if yes, what's
the value of iwintype for it?

best,

lj
