I changed main to main(WArg,HArg) ->
and this code:
W = WArg, %list_to_integer(atom_to_list(WArg)),
H = HArg, %list_to_integer(atom_to_list(HArg)),
MaxI = 255,
to just have single value and it works for testing. I'm still
wondering how to pass args in erl though - or is the [var1, var2]
always interpreted as command line args are expected?
