_D_e_s_c_r_i_p_t_i_o_n:

     These functions provide information about the Burr distribution
     with location parameter equal to 'm', dispersion equal to 's', and
     family parameter equal to 'f': density, cumulative distribution,
     quantiles, log hazard, and random generation.

     The Burr distribution has density

             f(y) = f s (y/m)^(s-1)/(m (1+(y/m)^s)^(f+1))

     where m is the location parameter of the distribution, s is the
     dispersion, and f is the family parameter.
