OOPPTTIIOONNSS _h_o_p_a_l_o_n_g accepts the following options: --wwiinnddooww Draw on a newly-created window. This is the default. --rroooott Draw on the root window. --mmoonnoo If on a color display, pretend we're on a monochrome display. --iinnssttaallll Install a private colormap for the window. --vviissuuaall _v_i_s_u_a_l Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --nnccoolloorrss _i_n_t_e_g_e_r How many colors should be used (if possible). Default 200. The colors used cycle through the hue, making N stops around the color wheel. --ccyycclleess _i_n_t_e_g_e_r How long to run each batch. Default 2500 pixels. --ccoouunntt _i_n_t_e_g_e_r How many pixels should be drawn before a color change. Default 1000. --jjoonngg _i_n_t_e_g_e_r --nnoo--jjoonngg _i_n_t_e_g_e_r Whether to use the Jong format (default is to choose randomly.)
