[gdal-dev] Passing Python PixelFunctionArguments or kwargs from command line?

[Scott]

With a python pixel function in a .vrt file, is it possible to pass 
values from the command line?

Example:
gdal_translate ... -lco PixelFunctionArguments=? or -lco -kwargs=?

Basically I want to change the 'min' and 'max' values on the command line:
<PixelFunctionArguments min="0" max="100" />

Thanks!
Scott
