       _r_g_b_._h_s_v_._s_h is a Bourne shell (sh(1)) program which converts RGB	values
       to  HSV	using _r_._m_a_p_c_a_l_c.  The Foley and Van Dam algorithm is the basis
       for the program.  Input must be three raster files - each file  supply-
       ing  the  RGB  values.  Three new raster files are created representing
       HSV.
