At a bare minimum, the docstring should explain precisely what one needs
to type to get a list of all valid colormaps. This could be included in a
docstring, so that when matplotlib changes the colormap options, the
docstring will suddenly break, and we will know to fix it.
Incidentally, right now one way to get a list of valid colormaps is to
just make a mistake with the cmap option, and a list of all valid options
is displayed.
{{{
sage: var('x,y')
sage: z = contour_plot(cos(x^2+y^2), (-4, 4), (-4, 4),cmap='foobar')
sage: z.save('a.png')
}}}
