Assuming the generated program is named a.out:

	a.out [-inputspace=space] [-algorithmspace=space] colours [pamfile]

Parameters:

-inputspace, -is
	Colour space of the input image. Valid values are 'bt709' (default),
	'srgb', and 'linear'. Ignored if the image's data is not colour data.

-algorithmspace, -as
	Colour space to run the quantization algorithm in. Valid values are
	'oklab' (default) and 'linear'. Ignored if the image's data is not
	colour data.

colours
	Desired number of colours in the palette. Fewer colours may be
	output if: the image already has fewer colours, or different floating
	point values get rounded to the same integer values.

pamfile
	Input file in PAM or PNM format. Also accepts stdin.
