- Takes a bunch of portable pixmap as input. Chooses _n_c_o_l_o_r_s
- colors to best represent all of the images, maps the
- existing colors to the new ones, and oooovvvveeeerrrrwwwwrrrriiiitttteeeessss tttthhhheeee iiiinnnnppppuuuutttt
- ffffiiiilllleeeessss with the new quantized versions.

- Verbose explanation: Let's say you've got a dozen pixmaps
- that you want to display on the screen all at the same time.
- Your screen can only display 256 different colors, but the
- pixmaps have a total of a thousand or so different colors.
- For a single pixmap you solve this problem with _p_p_m_q_u_a_n_t;
- this script solves it for multiple pixmaps. All it does is
- concatenate them together into one big pixmap, run _p_p_m_q_u_a_n_t
- on that, and then split it up into little pixmaps again.
-
- (Note that another way to solve this problem is to pre-
- select a set of colors and then use _p_p_m_q_u_a_n_t's ----mmmmaaaapppp option
- to separately quantize each pixmap to that set.)

- It's a csh script. Csh scripts are not portable to System
- V. Scripts in general are not portable to non-Unix
