       _s_._u_n_i_v_a_r   calculates  univariate  statistics  of  sites  lists.   This
       includes the number of sites, mean, standard deviation, coefficient  of
       variation,  mininum,  first quartile, median, third quartile, and maxi-
       mum.

       --aa     Use all sites found in the named _s_i_t_e_s file, rather than	limit-
	      ing  output  to  sites  falling  within  the  current geographic
	      region.

       --gg     Print  the  statistics  in  shell  script  style	 (similar   to
	      _g_._r_e_g_i_o_n).

       --ll     Use  site  descriptions  (category  labels) for z values.  Sites
	      must be in the (E|N|#n desc) format for this to  work.   Default
	      format  is  just	three  pipe-separated  floating  point numbers
	      (E|N|desc).

       --qq     Quiet. Cut out the chatter.

       Needs to do as many calculations as possible without storing individual
       site records (requires a lot of memory).
