--   This script allows you to specify two lists of plugins: one to always enable during rendering,
--   and one to always disable. The original state of the plugins is restored after rendering.

-- Define the lists of plugins to force-enable/disable

    end
    for i, plugin in ipairs(disablePlugins) do
      file:write("disable:".. plugin.. "\n")
    end
    file:close()
  end
