shaded relief maps in ferret?

[Lev Tarasov <lev@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi;
Has anybody put together a shaded colour relief routine for ferret
map projections? If so, could you please send me a script. If
not, any suggestions for another freely available package that
has this capability (though I'm really partial to ferret).

NB, dear ferret developers, this would be a great addition to the
next version of ferret. As far as I understand it, it just involves 
making the palette colour intensity/brightness a simple function of the
surface gradient.

thanks
